Can Someone Please Explain And Answer This For Me Im So Lost

Answers

Answer 1

Answer:

[tex]\left(\begin{array}{cc}0&24\\13&27\end{array}\right)[/tex]

Step-by-step explanation:

I will attempt to explain using the following example. Let us consider the  product (multiplication) of the following matrices:

[tex]\left(\begin{array}{cc}a_{1,1}&a_{1,2}\\a_{2,1}&a_{2,2}\end{array}\right) \cdot \left(\begin{array}{cc}b_{1,1}&b_{1,2}\\b_{2,1}&b_{2,2}\end{array}\right) = \left(\begin{array}{cc}c_{1,1}=c_{1\times 1}&c_{1,2}=c_{1\times2}\\c_{2,1}=c_{2\times1}&c_{1,2}=c_{2\times2}\end{array}\right)[/tex]

Note that the first number in each coefficient refers to the row number, while the second number refers to the column number.

Then [tex]a_{2,1}[/tex] indicates the element in the second row and first column.

To calculate the product of two matrices, we need to multiply each row of the first matrix by each column of the second matrix.

Example:

[tex]c_{1,1}= (a_{1,1} \cdot b_{1,1} + a_{1,2} \cdot b_{2,1})[/tex]

Now, we can apply this to the original exercise:

[tex]\left(\begin{array}{cc}5&-2\\4&1\end{array}\right) \left(\begin{array}{cc}2&6\\5&3\end{array}\right) =\left(\begin{array}{cc}c_{1,1}&c_{1,2}\\c_{2,1}&c_{2,2}\end{array}\right)[/tex]

Next, we will calculate each value of c using the multiplication process we just discussed.

[tex]c_{1,1}= (5(2)+-2(5)) = 10-10 =0\\c_{1,2}= (5(6)+-2(3)) = 30-6 =24\\c_{2,1}= (4(2)+1(5)) = 8+5 =13\\c_{2,2}= (4(6)+1(3)) = 24+3 =27\\[/tex]

Thus, we have obtained the final result of the matrix product:

[tex]\left(\begin{array}{cc}5&-2\\4&1\end{array}\right) \left(\begin{array}{cc}2&6\\5&3\end{array}\right) =\left(\begin{array}{cc}0&24\\13&27\end{array}\right)[/tex]

suppose the time a child spends waiting at for the bus as a school bus stop is exponentially distributed with mean 6 minutes. determine the probability that the child must wait at least 9 minutes on the bus on a given morning.

Answers

The probability that the child must wait at least 9 minutes on a given morning is approximately 0.2231.

Let X be the waiting time at the bus stop. We know that X is exponentially distributed with mean 6 minutes. Therefore, the probability density function (PDF) of X is given by:

f(x) = 1/6 * e^(-x/6) for x >= 0

To find the probability that the child must wait at least 9 minutes, we need to calculate the following probability:

P(X >= 9) = integral of f(x) from 9 to infinity

= integral from 9 to infinity of (1/6 * e^(-x/6)) dx

Using integration by substitution, let u = x/6, du = 1/6 dx, so that:

P(X >= 9) = integral from 3/2 to infinity of e^(-u) du

= [e^(-u)] evaluated from 3/2 to infinity

= e^(-3/2)

≈ 0.2231

Which inequality is not true?

- 7/8 < -0. 60
- 7/8 > -0. 50
-7/8 > - 15/16
- 7/8 < - 1/4

Answers

7/8 is greater than -0.50, greater than -15/16, and less than -1/4. All of these inequalities are true except for 7/8 being less than -0.60.

To solve the inequality 7/8 < -0.60, we need to manipulate it to get it in the form of an equation. First, we can multiply both sides of the inequality by 8, to get 7 < -8(0.60). Next, we can distribute the negative sign on the right side to get 7 < -4.80. Finally, we can subtract 7 from both sides of the equation to get 0 < -4.80 - 7, which equals 0 < -11.80. This means that 7/8 is not less than -0.60, which is the answer to the inequality.

To confirm this answer, we can also solve the inequality 7/8 > -0.50. Again, we can multiply both sides of the inequality by 8 to get 7 > -8(0.50). We can then distribute the negative sign to get 7 > -4. Now, if we subtract 7 from both sides of the equation, we get 0 > -4 - 7, which equals 0 > -11. This means that 7/8 is indeed greater than -0.50.

To further confirm our answer, we can solve the inequality 7/8 > -15/16.

consider the sample of 1,400 past negligence cases. suppose you are willing to let the 67% estimate be within .025 (2.5%) of the true proportion. you are willing to assume a 95% confidence. a. is 1,400 an adequate sample size for the estimate of 67%? show why or why not\

Answers

We can be reasonably confident that our estimate adequate sample size of 67% is within 2.5% of the true proportion.

To determine if a sample size of 1,400 is adequate for estimating a proportion of 67%, we need to calculate the margin of error and compare it to the given tolerance level of 0.025.

We can use the following formula to calculate the margin of error:

[tex]E = z \sqrt{\frac{(p (1-p)}{n} )[/tex]

where:

E is the margin of errorz is the z-score corresponding to the desired confidence level (95% corresponds to a z-score of 1.96)p is the estimated proportion (67% or 0.67 as a decimal)n is the sample size (1,400)

Plugging in the values, we get:

[tex]E = 1.96 \sqrt{(0.67 (1-0.67)/1400)[/tex]

≈ 0.025

Thus, the error margin is around 0.025. This indicates that there is a 95% chance that the real percentage will be within 0.025 of the estimated proportion.

We may infer that a sample size of 1,400 is sufficient for predicting a proportion of 67% with the provided degree of confidence and tolerance as the computed margin of error is equal to the required tolerance level. As a result, we can say with some degree of assurance that our estimate of 67% is within 2.5% of the actual proportion.

Answers

To find the percentage increase in price from yesterday's price to today's price, we can use the following formula:

Percentage Increase = ((New Value - Old Value) / Old Value) x 100

Plugging in the given values, we get:

Percentage Increase = ((2.75 - 2.40) / 2.40) x 100

Percentage Increase = (0.35 / 2.40) x 100

Percentage Increase = 0.1458 x 100

Percentage Increase = 14.58%

Therefore, the percentage increase in price from yesterday's price to today's price is 14.58%, rounded to the nearest tenth of a percent.

Answers

m/EFH = 109° and m/EFG = 18°. Angles in a straight line sum to 180°. Since m/GFH is 71°, the remaining angle measures must add up to the remaining 109°. Therefore, m/EFH must be 109° and m/EFG must be 18°.

To find m/EFH and m/EFG, we need to use the fact that angles in a straight line sum to 180°. We can use this fact to work out the missing angle measures.

First, we note that m/GFH is 71°. This means that the remaining angles must add up to the remaining 109°.

We can then calculate m/EFH by subtracting m/GFH from 180°. m/EFH is therefore 180° - 71° = 109°.

Next, we can calculate m/EFG by subtracting m/EFH from 180°. m/EFG is therefore 180° - 109° = 18°.

Therefore, m/EFH = 109° and m/EFG = 18°.

what is the rate of change between 75 and 125 miles driven

Answers

The rate of change between 75 and 125 miles is calculated by dividing the difference between the fuel cost at 125 and 75 miles by the distance traveled. The fuel cost at 75 miles is $3.85, while the fuel cost at 125 is $6.35. The rate of change is $0.05 per mile.

What is the rate of change of the cost of fuel when the car travels from 75 miles to 125 miles?

To calculate the rate of change between 75 and 125 miles, subtract the fuel cost at 125 miles from the fuel cost at 75 miles and divide the difference by the distance travelled:

Rate of change = (fuel cost at 125 miles - fuel cost at 75 miles) / (125 - 75)

First, we need to find the fuel cost at 75 miles:

() = 0.1 + 0.05x

() = 0.1 + 0.05(75)

() = 3.85

The fuel cost at 75 miles is $3.85.

Next, we need to find the fuel cost at 125 miles:

() = 0.1 + 0.05x

() = 0.1 + 0.05(125)

() = 6.35

The fuel cost at 125 miles is $6.35.

Now we can substitute these values into the rate of change formula:

Rate of change = (6.35 - 3.85) / (125 - 75)

Rate of change = 2.5 / 50

Rate of change = 0.05

The rate of change of the cost of fuel when the car travels from 75 miles to 125 miles is $0.05 per mile.

The triangle ABC id mapped onto triangle A' B'C' with vertices A'(3,1) , B'(1,-2) , C'(1,2)
Under the translation T= (2/3)Find the vertices of triangle ABC. (No need to draw).

Answers

Step-by-step explanation:

To find the vertices of triangle ABC after the translation T = (2/3), we can use the following formula:

(x', y') = (x + 2/3, y + 2/3)

where (x, y) are the coordinates of the original point and (x', y') are the coordinates of the translated point.

Using this formula, we can translate each vertex of triangle A'B'C' back to its original position:

Vertex A:

x = 3 - 2/3 = 7/3

y = 1 - 2/3 = 1/3

Therefore, the coordinates of vertex A in triangle ABC are (7/3, 1/3).

Vertex B:

x = 1 - 2/3 = 1/3

y = -2 - 2/3 = -8/3

Therefore, the coordinates of vertex B in triangle ABC are (1/3, -8/3).

Vertex C:

x = 1 - 2/3 = 1/3

y = 2 - 2/3 = 4/3

Therefore, the coordinates of vertex C in triangle ABC are (1/3, 4/3).

Therefore, the vertices of triangle ABC are (7/3, 1/3), (1/3, -8/3), and (1/3, 4/3).

Answer:

Let A(x1, y1), B(x2, y2), and C(x3, y3) be the vertices of triangle ABC.

Under the translation T, each point (x, y) is mapped to the point (x + 2/3, y), which means that the new coordinates of A, B, and C will be:

A' = (x1 + 2/3, y1)

B' = (x2 + 2/3, y2)

C' = (x3 + 2/3, y3)

We are given the coordinates of A' (3, 1), B' (1, -2), and C' (1, 2), so we can set up a system of equations to solve for the coordinates of A, B, and C:

x1 + 2/3 = 3 => x1 = 2 1/3

y1 = 1

x2 + 2/3 = 1 => x2 = 1/3

y2 = -2

x3 + 2/3 = 1 => x3 = 1/3

y3 = 2

Therefore, the vertices of triangle ABC are A(2 1/3, 1), B(1/3, -2), and C(1/3, 2).

8: (8 - 1)/2 = 3.5 (not a natural number)

11: (11 - 1)/2 = 5

16: (16 - 1)/2 = 7.5 (not a natural number)

19: (19 - 1)/2 = 9

22: (22 - 1)/2 = 10.5 (not a natural number)

solve the system of inequalities for y+3x<5 and 1>2x-y ?

Answers

The shaded region is below both lines, and the boundary line y = 2x - 1 is dashed because the inequality is strict. The solution can be described as: y < 5 - 3x and y < 2x - 1.

What is inequality?

Inequality is a mathematical statement that compares two values or expressions. It uses symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to) to indicate the relationship between the two expressions. Inequalities are used to represent a range of possible values, rather than just a single value as in an equation.

Here,

We have the system of inequalities:

y + 3x < 5

2x - y > 1

To solve this system, we can start by isolating y in each inequality:

y < 5 - 3x

y < 2x - 1

Now we can graph each inequality on the coordinate plane and shade the region that satisfies both inequalities.

For the first inequality y < 5 - 3x, we can start by graphing the line y = 5 - 3x. This line has a y-intercept of 5 and a slope of -3. Since the inequality is y < 5 - 3x, we need to shade the region below the line.

For the second inequality y < 2x - 1, we can start by graphing the line y = 2x - 1. This line has a y-intercept of -1 and a slope of 2. Since the inequality is 2x - y > 1, we need to shade the region below the line.

The solution to the system is the region that is shaded by both inequalities. Here is a graph of the solution:

 5 |- - - -/---- - - - - - - -

Answers

The length of the best that is with the contact of rim of the pulley is (5/18)π cm.

The shaded region is 10√5 - (5/18)π cm.

How to calculate length of belt in a pulley?

To find the length of the belt that is in contact with the rim of the pulley, we need to find the length of the arc of the circle with radius 5 cm that is between the points O and P.

The circumference of a circle with radius 5 cm is 2πr = 10π cm. So the fraction of the circle between O and P is 10/360 = 1/36 of the total circumference. Therefore, the length of the arc OP is (1/36) x 10π = (5/18)π cm.

To find the shaded region, we need to subtract the length of the belt in contact with the pulley from the length of the belt pulled to point P.

The belt pulled to point P is the hypotenuse of a right triangle with legs 5 cm (the radius of the pulley) and 10 cm (the distance from the center of the pulley to point P). Using the Pythagorean theorem, we can find the length of the belt pulled to point P:

h² = 5² + 10²

h² = 125

h = √125 = 5√5 cm

So the length of the belt pulled to point P is 2(5√5) = 10√5 cm.

Therefore, the length of the shaded region is 10√5 - (5/18)π cm. This is the length of the part of the belt that is not in contact with the pulley.

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 12 feet and a height of 19 feet. Container B has a diameter of 16 feet and a height of 12 feet. Container A is full of water and the water is pumped into Container B until Container A is empty.

After the pumping is complete, what is the volume of water in Container B, to the nearest tenth of a cubic foot?

Answers

The volume of a cylinder is given by the formula V = πr^2h, where r is the radius of the base and h is the height.

For Container A, the radius is half the diameter, so r = 6 feet. The volume of water in Container A is V_A = π(6^2)(19) ≈ 2154.4 cubic feet.

After pumping all the water from Container A into Container B, the height of the water in Container B will be the same as the height of Container A, which is 19 feet. The radius of Container B is half the diameter, so r = 8 feet. The volume of water in Container B is therefore V_B = π(8^2)(19) ≈ 3831.0 cubic feet.

Subtracting the volume of water that was originally in Container A, we get:

V_B - V_A ≈ 3831.0 - 2154.4 ≈ 1676.6 cubic feet

Therefore, the volume of water in Container B after pumping is approximately 1676.6 cubic feet to the nearest tenth.

a bookstore took an inventory of the prices of its books and created a histogram to show the results. what shape does the distribution have?

Answers

The required shape of the attached histogram of the prices of the books is given as bell shaped.

General characteristics of histograms ,based on some general observations are,

If the histogram is roughly symmetric around its center, then the distribution is likely to be approximately normal (bell-shaped).

If the histogram has a peak on one side and a long tail on the other, then the distribution is likely to be skewed (either positively or negatively skewed).

If the histogram has multiple peaks or modes, then the distribution is likely to be multimodal.

Based on these observations,

The shape of the distribution in the bookstore's inventory is bell shaped.

As here in the attached histogram is symmetric around its center.

It is almost symmetric between 100 to 150 dollars.

Therefore, the shape of the distribution of the prices of books is bell shaped in the attached histogram.

Answers

The independent variable is the number of snacks purchased, denoted by "s", and the dependent variable is the total cost, denoted by "$". The relationship is linear, with $ = 3s + 15.

What is rate?

A rate is a measure of the amount of change of one quantity with respect to another quantity, often expressed as a ratio or a fraction. It tells us how much one quantity changes per unit of time or per unit of another quantity. Examples of rates include speed, velocity, acceleration, interest rate, and growth rate

According to the given information:

In the given table, the independent variable is the number of snacks purchased, denoted by "s", and the dependent variable is the total cost, denoted by "$".

The relationship between the number of snacks purchased and the total cost is a linear relationship, where the total cost increases by $3 for every additional snack purchased.

We can write the equation for the relationship between the two variables as:

$ = 3s + 15

Here, the constant term 15 represents the fixed cost or the cost of buying zero snacks. The coefficient 3 of the independent variable "s" represents the additional cost incurred for each additional snack purchased.

Therefore, The independent variable is the number of snacks purchased, denoted by "s", and the dependent variable is the total cost, denoted by "$". The relationship is linear, with $ = 3s + 15.

Find x and y . I don’t understand. Math help plsssss

Answers

Answer:

x = y = 5

Step-by-step explanation:

This triangle and its markings show that the acute angles are equal. Given that it is a right triangle, this is a 45-45-90 triangle. This also means that the values of x and y are equal. Note that for any triangle, if two angles are equal, then their corresponding side lengths are also equal. The side lengths for this type of triangle follow the pattern s - s - s√2 where the first two are side lengths and last value is the length of the hypotenuse. (s represents the length of a side)

We want to find x and y, so we need the value of s.

s√2 = 5√2
s = 5

Therefore, x = 5, y = 5.

The numbers of beads on 500 handcrafted bead necklaces follow a normal distribution whose mean is 24 beads and standard deviation is 4 beads. Which sentence most closely summarizes the data?

Answers

The statement which most closely summarizes the data is that about 80 necklaces have more than 28 beads. The solution has been obtained by using the standard deviation.

What is standard deviation?

The standard deviation measures how skewed the data are with respect to the mean. Data are said to be more densely grouped around the mean and more dispersed, respectively, when the standard deviation is low and large.

We are given that the mean for the normal distribution is 24 beads and the standard deviation is 4 beads.

Now,

⇒ P (X ≥ 28) = 1 - P (X < 28)

⇒ P (X ≥ 28) = 1 - P ([tex]\frac{X-24}{4}[/tex] < 1)

⇒ P (X ≥ 28) = 1 - P (Z < 1)

⇒ P (X ≥ 28) = 1 - 0.84

⇒ P (X ≥ 28) = 0.16

Now, since the total necklaces are 500, the necklaces which have more than 28 beads are as follows:

⇒ 500 * 0.16

⇒ 80 necklaces

Hence, the third option is the correct answer.

The allowable range for an objective function coefficient assumes that the original estimates for all the other coefficients are completely accurate so that this is the only one whose true value may differ from its original estimate.T/F

Answers

The given statement " The allowable range for an objective function coefficient assumes that the original estimates for all the other coefficients are completely accurate so that this is the only one whose true value may differ from its original estimate " is false because the allowable range for an objective function coefficient assumes that the original estimates for other coefficients are approximately correct

The allowable range for an objective function coefficient assumes that the original estimates for all the other coefficients are approximately correct, but not necessarily completely accurate. The allowable range takes into account the potential variability or uncertainty in the estimated values of the other coefficients, as well as the impact of any errors or discrepancies in the data used to estimate the model.

Therefore, the allowable range provides a range of values within which the objective function coefficient can vary while still producing a valid and useful model. It does not assume that the other coefficients are completely accurate or that this is the only coefficient whose true value may differ from its original estimate.
