The number of days in which Meena would be able to complete the work alone is 24 days.
How to determine the required number of days?In order to determine the number of days in which Meena would be able to complete the work alone, we would have to assign variables to the amount of time taken by Mala, Meena, and Vinay, and then translate the word problem into an algebraic equation as follows;
Let the variable y represent the number of days taken by Mala.Let the variable x represent the number of days taken by Meena.Let the variable z represent the number of days taken by Vinjay.Note: Combined work rate = 1/x + 1/y + 1/z
Based on the information provided, we have the following equations that models the work rate by each person;
1/(x + y) = 10 ⇒ 1/10 = x + y ........equation 1.
1/(y + z) = 12 ⇒ 1/12 = y + z ........equation 2.
1/(x + z) = 15 ⇒ 1/15 = x + z ........equation 3.
x + y + y + z + x + z = 1/10 + 1/12 + 1/15
2(x + y + z) = 15/60
2(x + y + z) = 1/4
x + y + z = 1/8
From equation 2, we have:
x + (y + z) = 1/8
x + 1/12 = 1/8
x = 1/8 - 1/12
x = 1/24
x = 24 days.

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).

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.

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
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.
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 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.

m/EFH=
m/EFG =
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°.

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.

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.

- 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.

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

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.

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.

Mason subtracted 5 from each side instead of adding 5.
x - 5 < 11
x - 5 + 5 < 11 + 5
x < 16
The number line will have an open circle at 16 since it does not include
16. It will be shaded to the left from that open circle as it includes
all values less than 16.
Adriana opened a savings account 3 years ago. The account earns 7% interest, compounded quarterly. If the current balance is $300.00, how much did she deposit initially?
Answers
Answer: 243.617
Step-by-step explanation:
300 = [tex]x[/tex] x (1 + 7/100/4)^(4 x 3)
300 = [tex]x[/tex] x (1.0175)^12
300 = [tex]x[/tex] x 1.231
[tex]x[/tex] = 300/1.231
[tex]x[/tex] = 243.617
the price of a cup of coffee has risen to $2.75 today. yesterday's price was $2.40. find the percentage increase. round your answer to the nearest tenth of a percent.
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.
