Find the equation of a line with the given informatio f(-6) = 9 and f (20) = 5.

Answer: 16

Step-by-step explanation:

4*4 = 16

Thus, the parking space is longer than length of the truck by 42 inches.

The same attribute is expressed using a unit conversion, but in a different measurement equivalent. For instance, time can always be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or another type of measurement unit instead of miles.

Using conversion factors, existing units, and or the fact that a unit of measure cancels out another unit of measure, a unit cancellation table is created.

Given data:

Length of the parking space = 60 feet

Length of truck = 6 yard.

Convert yards in feet

1 yard = 3 feet

Multiply both side by 6.

6*1 yard = 6*3 feet

6 yard = 18 feet

Difference = 60 - 18 = 42 feet.

The parking space is longer than length of the truck by 42 inches.

If we take multiple samples of the same size and calculate their means, 90% of the resulting sample which is 69.3 means will fall within 9.02 units of the true population mean for standard deviation.

The following formula must be used to determine the margin of error for a 90% confidence interval for the population mean ():

Margin of error =  [tex]z * (/n)[/tex].

where is the population standard deviation, n is the sample size, and z is the critical value from the standard normal distribution with a 90% confidence level.

The matching z-value is 1.645 because a 90% confidence interval is what we are looking for. Thus, the margin of error can be determined as follows:

Margin of error: (50 / 77) / 1.645 = 9.02

This indicates that 90% of the sample means obtained when calculating the means of several samples of equal size will be within 9.02 units of the actual population mean.

It is significant to remember that the margin of error lowers with sample size and rises with confidence level. A bigger sample size in this situation would lead to a smaller margin of error, whereas a greater confidence level would lead to a larger margin of error.

Mr Leonard will receive a discount of £45.84 on his oil purchase.

We must first determine the entire amount of oil Mr. Leonard intends to buy in order to determine the discount he will receive.

There are currently 450 liters in the tank, which has a capacity of 1200 liters. Therefore, Mr. Leonard needs to buy an extra 750 liters (1200 - 450 = 750).

The total cost of the oil before the discount must then be determined.

With a litre costing 81.5p, the price for 750 liters of oil would be:

750 liters x 81.5 pence per liter = £611.25.

We must multiply the entire cost of the oil by the discount rate (7.5 percent, or 0.075), in order to determine the discount:

£611.25 x 0.075 = £45.84

Therefore, Mr Leonard will receive a discount of £45.84 on his oil purchase.

First, we need to pick two points from the line which would be ( 0, 5 ) and ( -5, 2 ).

To find the values of m (slope) and b (y-intercept) for a line with the given coordinates (0, 5) and (-5, 2), we can use the slope formula and the point-slope form of a linear equation.

Calculate the slope (m) using the slope formula:

m = (y2 - y1) / (x2 - x1)

m = (2 - 5) / (-5 - 0)

m = (-3) / (-5)

m = 3/5

Find the y-intercept (b) using the point-slope form. The y - intercept is the point where the line crosses the y axis. This means that the value of x at this point would be 0.

Step-by-step explanation:

As a salesperson at Trading Cards Unlimited, Justin receives a monthly base pay plus commission on all that he sells. If he sells $400 worth of merchandise in one month, he is paid $384. If he sells $700 of merchandise in one month, he is paid $447.

Answer:

Step-by-step explanation:

To solve this problem, we can set up a system of two equations with two variables. Let x be Justin's base pay for the month and y be the commission rate he receives for each dollar of merchandise sold. Then we have:

400y + x = 384 (equation 1)

700y + x = 447 (equation 2)

To solve for x and y, we can use the method of substitution. Solving equation 1 for x, we get:

x = 384 - 400y

Substituting this expression for x into equation 2, we get:

700y + (384 - 400y) = 447

Simplifying and solving for y, we get:

300y = 63

y = 0.21

Substituting this value of y into equation 1, we can solve for x:

400(0.21) + x = 384

x = 304.80

Therefore, Justin's base pay for the month is $304.80 and he receives a commission of 21% on all merchandise sold.

r = 0,5 × 16 = 8 cm

The circumference of the circle is equal to:

[tex]c = 2\pi \times r[/tex]

[tex]c = 2\pi \times 8 = 16\pi \: {cm}^{2} [/tex]

Therefore , the solution of the given problem of triangle comes out to be the triangle has a side c of 2.15 and angles A = 42.5°, B = 0°, and C = 40.3°.

If a polygon has at least one additional segment, it is a hexagon. Its structure is a simple rectangle. Something like this can only be distinguished from a regular triangular form by edges A and B. Euclidean geometry only creates a portion of the cube, despite the precise collinearity of the borders. A triangular has three sides and three angles.

Here,

The centers of the three circles must make an equilateral triangle because they are positioned so that they touch one another. Angles A and C are both 60 degrees, so we know this.

With lengths that are 5.4 and 4.4 in length, we can use the Law of Cosines to determine angle A:

=> cos(A) = (4.4² + 5.4² - 3.4²) / (2 * 4.4 * 5.4)

=> cos(A) = 0.731

=> A = cos⁻¹(0.731)

=>A ≈ 42.5°

We can apply the Law of Cosines once more to determine side b:

=> b² = 4.4² + 5.4^2 - 2 * 4.4 * 5.4 * cos(60)

=> b ≈ 2.15

Finally, we can apply the Law of Sines to determine angle C:

=> Sin(60) / 2.15 = sin(C) / 5.4 =

=> sin(C) ≈ 0.635

=> C ≈ sin⁻¹(0.635)

=> C ≈ 40.3°

As a result, the triangle has a side c of 2.15 and angles A = 42.5°, B = 0°, and C = 40.3°.

Selection bias occurs when the selection of the sample is not random and is instead influenced by factors that are not related to the study objective. Here are some examples of selection bias in a survey of brown-eyed people:

A survey that only includes brown-eyed people from a specific geographic location, such as a single city or state. This would not be representative of the entire population of brown-eyed people.

A survey that only includes brown-eyed people who are members of a particular organization or club. This would not be representative of the entire population of brown-eyed people, as it would exclude those who are not members of the organization or club.

A survey that only includes brown-eyed people who have a certain level of education or income. This would not be representative of the entire population of brown-eyed people, as it would exclude those with different levels of education or income.

A survey that only includes brown-eyed people who are willing to participate in the study. This could result in a biased sample, as those who are not willing to participate may have different characteristics than those who are willing to participate.

In general, any selection process that is not random and does not provide equal opportunity for all members of the population to be included in the study can result in selection bias.

Answer:

B) 102

Step-by-step explanation:

To find x, we need to simplify and solve the equation (5x+6)=(7x-12):

5x + 6 = 7x - 12 // distribute the 5 and 7

6 + 12 = 7x - 5x // group the x terms and constants

18 = 2x

Now, we can solve for x by dividing both sides by 2:

18/2 = x

9 = x

Therefore, x is 9.

To find the solution if x = 9, we can simply substitute 9 for x in the given expressions:

(5x+6) = (5(9) + 6) = 51

(7x-12) = (7(9) - 12) = 51

Therefore, both expressions are equal to 51 when x = 9.

The probability that the average sleeping time for a randomly selected sample of 36 students is more than 6 hours per night is 0.8413.

Probability is a branch of mathematics that deals with the measurement of the likelihood or chance of an event occurring. It is used to quantify uncertainty and make predictions based on incomplete information. In general, probability is defined as a number between 0 and 1, where 0 represents an event that is impossible, and 1 represents an event that is certain to occur.

The basic concept of probability is based on the ratio of the number of favorable outcomes to the total number of possible outcomes. For example, if we toss a fair coin, the probability of getting heads is 1/2 or 0.5, since there is one favorable outcome (heads) out of two possible outcomes (heads or tails).

We can use the central limit theorem to approximate the distribution of the sample mean, assuming that the sample size is large enough. Since the sample size is n=36, we can assume that the sample mean has a normal distribution with mean μ=6.1 and standard deviation σ/√n=0.6/√36=0.1.

Let X be the sample mean sleeping time per night. Then we need to find the probability P(X > 6), which can be transformed into a standard normal distribution using the formula:

Z = (X - μ) / (σ/√n)

where Z is the standard normal variable.

Substituting the given values, we get:

Z = (6 - 6.1) / (0.1) = -1

Now we need to find the probability that Z is greater than -1. Using a standard normal distribution table or calculator, we can find that the probability is approximately 0.8413.

Therefore, the probability that the average sleeping time for a randomly selected sample of 36 students is more than 6 hours per night is 0.8413.

What is mean?

In statistics, the mean (also known as the arithmetic mean or average) is a measure of central tendency that represents the sum of a set of numbers divided by the total number of numbers in the set.

To find the IQR for the mean of 15 pumpkins, we need to first find the standard error of the mean, which can be calculated using the formula:

SEM = σ / sqrt

where SEM is the standard error of the mean, σ is the standard deviation, and n is the sample size.

SEM = 1.68 / sqrt(15) = 0.433

The interquartile range (IQR) for the mean can be calculated as:

IQR = 1.35 * SEM

where 1.35 is the multiplier for the IQR based on the normal distribution.

Substituting the value of SEM, we get:

IQR = 1.35 * 0.433 = 0.585

There are 2500 Shaded squares and 7500 unshaded squares in the 100x100 square, based on the given sequence in the diagram.

1. First, analyze the given diagram and observe the pattern. Notice that there are alternating shaded and unshaded squares, with the shaded squares being on the main diagonal.

2. Next, identify the sequence in the pattern. It appears that there is a continuous increase of shaded squares, starting from 1 and increasing by 2 each time. This forms an arithmetic sequence: 1, 3, 5, 7, and so on.

3. To find the number of shaded squares in the 100x100 square, calculate the sum of the first 50 terms of the sequence (since there are 100 rows/columns and each shaded area covers 2 rows/columns). The formula for the sum of an arithmetic sequence is: Sn = n * (a1 + an) / 2, where Sn is the sum of the sequence, n is the number of terms, a1 is the first term, and an is the last term.

4. In our case, n = 50, a1 = 1, and an = 99 (the 50th term in the sequence). Plugging these values into the formula, we get: S50 = 50 * (1 + 99) / 2 = 50 * 100 / 2 = 2500.

5. Thus, there are 2500 shaded squares in the 100x100 square.

6. To find the number of unshaded squares, subtract the number of shaded squares from the total number of squares in the 100x100 square. The total number of squares is 100 * 100 = 10,000.

7. Now, calculate the number of unshaded squares: 10,000 - 2500 = 7500.

In conclusion, there are 2500 shaded squares and 7500 unshaded squares in the 100x100 square, based on the given sequence in the diagram.

Thus, the given side of triangle with lengths of 63 inches, 73 inches, and 98 inches does not form a right triangle.

A triangle is considered to be correct when one of its angles is 90 degrees. Moreover, a right angle is one that measures 90 degrees or more.

The non-right angle measurements of right triangles must add up to 90 degrees, which is a crucial condition. This results from the fact that a triangle's total number of angles equals 180 degrees.

In right triangle, the longest side is called hypotenuse.

Then,

hypotenuse H = 98 inches

Let Side S1 = 63 inches,

Let Side S2 = 73 inches,

Then, Pythagorean theorem must satisfy for right triangle

H² = (S1)² + (S2)²

98² = (63)² + (73)²

what is triangle ?

With three consecutive sides and three angles, a triangle is an enclosed plane shape. It is one of the fundamental geometric shapes and is frequently used in physics, maths, and engineering. A triangle's total angles are always 180 degrees. Triangles come in a variety of shapes, such as equilateral triangles, which have three equal sides and angles, isosceles triangles, which have two equal sides and angles, and scalene isosceles (all sides and angles are different).

To determine the type of triangle based on the given side lengths, we can use the following rules:

If all three sides are equal, it's an equilateral triangle.

If two sides are equal, it's an isosceles triangle.

If all three sides are different, it's a scalene triangle.

We can also use the Pythagorean theorem to determine if the triangle is a right triangle. According to this theorem, in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.

Let's check the sides of the given triangle using these rules:

The three sides are different, so it's a scalene triangle.

To check if it's a right triangle, we can find the longest side (53) and see if it satisfies the Pythagorean theorem with the other two sides. Using a calculator, we find that [tex]28^2 + 45^2 = 784 + 2025 = 2809[/tex], and [tex]53^2 = 2809.[/tex]Therefore, the triangle is a right triangle.

Therefore, the solution to fg(x) = gf(x) for the composite functions is x = -1/4.

A function is a mathematical rule that assigns a unique output for every input in a given set. In other words, it is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. A function can be represented using a formula, a graph, or a table of values. Functions are widely used in mathematics, science, engineering, economics, and many other fields to describe the relationship between variables and to make predictions based on data.

Here,

To solve fg(x) = gf(x), we need to find f(g(x)) and g(f(x)), and then set them equal to each other.

f(g(x)) = f(x + 1)

= 2(x + 1)²

= 2(x² + 2x + 1)

= 2x² + 4x + 2

g(f(x)) = g(2x²)

= 2x² + 1

Now we can set them equal to each other and solve for x:

2x² + 4x + 2 = 2x² + 1

Subtracting 2x² from both sides, we get:

4x + 2 = 1

Subtracting 2 from both sides, we get:

As a result, the system of equations has the following solution: x=-2,y=16,z=11.

In order to resolve the equation system:

x + y - z = 3

x - 3y - 2z = -28 and 4x - y + z = -13

The elimination strategy can be used to find the values of x, y, and z. In order to remove z, we can first add the first and second equations:

3 - 13x + y - z + 4x - y + z

A approach for solving systems of linear equations is the elimination method. The addition method is another name for it. We change an equation system so that one variable "cancels out" in order to solve it by elimination. In this approach, one of the variables is removed by adding or subtracting from the equations. After removing one variable, we can find a solution for the remaining one.

When we simplify this equation, we obtain:

5x = -10

When we multiply both sides by 5, we get:

x = -2

Knowing x now allows us to solve for y by substituting it into the first equation:

-2 + y - z = 3

When we simplify this equation, we obtain:

y - z = 5

In order to solve for z, we may now enter x and y into the third equation:

-2 - 3y + 2z = -28

When we simplify this equation, we obtain:

-3y + 2z = -26

by replacing  y - z = 5 to this equation gives us:

-3y + 2(y - 5) = -26

When we simplify this equation, we obtain:

-y - 10 = -26

To both sides of the equation, add 10, and we get:

-y = -16

Adding -1 to both sides gives us:

y = 16

Knowing x and y now allows us to solve for z by substituting them into the first equation:

-2 + 16 - z = 3

When we simplify this equation, we obtain:

z = 11
