an inlet pipe on a swimming pool can be used to fill the pool in 26 hours. the drain pipe can be used to empty the pool in 30 hours. if the pool is 25 filled and then the inlet pipe and drain pipe are opened, how many more hours would it take to fill the pool? round your answer to two decimal places, if needed.

Answers

The total time required to fill the pool completely as per the inlet and drain pipe capacity is given by 146.25 hours.

Let's assume that the capacity of the pool is 1 unit .

The inlet pipe can fill the pool at a rate of 1/26 units per hour.

The drain pipe can empty it at a rate of 1/30 units per hour.

When both pipes are open,

The net rate of filling is the difference between the rate of filling and the rate of emptying,

Net rate = Rate of filling - Rate of emptying

⇒Net rate = 1/26 - 1/30

⇒Net rate = (30 -26 )/780

⇒Net rate = (4)/780

⇒Net rate = 1/195 units per hour

Since the pool is already 25% filled.

This implies,

It still needs to be filled by another 0.75 units.

The time required to fill the pool by 0.75 units at a net rate of 1/195 units per hour can be found using the formula,

Time = Amount of filling needed / Net rate

⇒Time = 0.75 / (1/195)

⇒Time = 146.25 hours

Therefore, the total time taken to fill the pool completely would take another 146.25 hours.

Suppose you have an outdoor vegetable garden with dimensions 2 mx2 m. A storm lasting 1 hr delivers 0.8 inches of rain. a. What is the storm rainfall flux? Express your answer using each of the following units: m 2
hr
kgliquid water m 2
hr
lb liquid water m 2
hr
liters liquid water m 2
hr
gallons liquid water b. How much liquid water fell on your garden? Express your answer using each of the following units:

Answers

The storm rainfall flux is 0.00127 m2/hr, 1.27 kg liquid water/m2hr, 2.8 lb liquid water/m2hr, 1.27 liters liquid water/m2hr, and 0.335 gallons liquid water/m2hr. The amount of liquid water fell on the garden is 80.6 L, 21.3 gallons.

Dimensions of outdoor vegetable garden = 2 m × 2 m

Storm rainfall = 0.8 inches of rain

Time of storm = 1 hr(

a) The rainfall flux is the amount of rainfall per unit area and unit time. It is given as:

Rainfall flux = (Amount of rainfall) / (Area × Time)

Given the area of the garden is 2 m × 2 m, and the time is 1 hr, the rainfall flux is:

Rainfall flux = (0.8 inches of rain) / (2 m × 2 m × 1 hr)

Converting inches to meters, we get:

1 inch = 0.0254 m

Therefore,

Rainfall flux = (0.8 × 0.0254 m) / (2 m × 2 m × 1 hr) = 0.00127 m/hr

Converting the rainfall flux to other units:

In kg/hr:

1 kg of water = 1000 g of water

Density of water = 1000 kg/m3

So, 1 m3 of water = 1000 kg of water

So, 1 m2 of water of depth 1 m = 1000 kg of water

Therefore, 1 m2 of water of depth 1 mm = 1 kg of water

Therefore, the rainfall flux in kg/hr = (0.00127 m/hr) × (1000 kg/m3) = 1.27 kg/m2hr

In lbs/hr:

1 lb of water = 453.592 g of water

So, the rainfall flux in lbs/hr = (0.00127 m/hr) × (1000 kg/m3) × (2.20462 lb/kg) = 2.8 lbs/m2hr

In liters/hr:

1 m3 of water = 1000 L of water

So, 1 m2 of water of depth 1 mm = 1 L of water

Therefore, the rainfall flux in L/hr = (0.00127 m/hr) × (1000 L/m3) = 1.27 L/m2hr

In gallons/hr:

1 gallon = 3.78541 L

So, the rainfall flux in gallons/hr = (0.00127 m/hr) × (1000 L/m3) × (1 gallon/3.78541 L) = 0.335 gallons/m2hr

(b) To calculate the amount of water that fell on the garden, we need to calculate the volume of water.

Volume = Area × Depth.

The area of the garden is 2 m × 2 m.

We need to convert the rainfall amount to meters.

1 inch = 0.0254 m

Therefore, 0.8 inches of rain = 0.8 × 0.0254 m = 0.02032 m

Volume of water = Area × Depth = (2 m × 2 m) × 0.02032 m = 0.0806 m3

Converting the volume to other units:

In liters:

1 m3 of water = 1000 L of water

Therefore, the volume of water in liters = 0.0806 m3 × 1000 L/m3 = 80.6 L

In gallons:

1 gallon = 3.78541 L

Therefore, the volume of water in gallons = 80.6 L / 3.78541 L/gallon = 21.3 gallons.

I believe this is talking about the vertical, and horizontal lines that are drawn to connect the diagonal line(the line by itself); for the rise, and run; or change in y over change in x. This forms right(90 degree) triangles with the change in y being the vertical part, the change in x being the horizontal part, and the diagonal part being the slope to connect the start, and finishing point.

From observing the graph, you can tell that the x axis counts by 1/2 every unit, and that the y axis counts by 1 every unit.

Since the y goes down 1 every unit and to the right 1 every unit with an x axis that counts by 1/2, and a y axis that counts by 1:

slope = change in y / change in x = -1 × 1 / 1 × 1/2 = -1 / 1/2 = -2 [this is the slope]

The philanthropic organization in Exercise 1 expects about a 5%success rate when they send fundraising letters to the people on their mailing list. In Exercise 1 you looked at the histograms showing distributions of sample proportions from 1000 simulated mailings for samples of size and The sample statistics from each simulation were as follows:a) According to the Central Limit Theorem, what should the theoretical mean and standard deviations be for these sample sizes?b) How close are those theoretical values to what was observed in these simulations?c) Looking at the histograms in Exercise at what sample size would you be comfortable using the Normal model as an approximation for the sampling distribution?d) What does the Success/Failure Condition say about the choice you made in part c?

Answers

The Normal model is a good approximation for the sampling distribution.

a) According to the Central Limit Theorem, the theoretical mean and standard deviation for a sample size of 20 should be 0.05 and 0.02, respectively. For a sample size of 100, the theoretical mean and standard deviation should be 0.05 and 0.01, respectively.

b) The observed mean and standard deviation for a sample size of 20 was 0.052 and 0.021, respectively. For a sample size of 100, the observed mean and standard deviation was 0.051 and 0.012, respectively. These values are fairly close to the theoretical values.

c) Looking at the histograms in Exercise 1, I would be comfortable using the Normal model as an approximation for the sampling distribution at a sample size of 100.

d) The Success/Failure Condition states that the sample size should be large enough for the sampling distribution of the sample proportions to be approximately normal. Since I chose a sample size of 100, which satisfied the condition, I can be confident that the Normal model is a good approximation for the sampling distribution.

The sample size of 100 is large enough for the sampling distribution of the sample proportions to be approximately normal, and the observed mean and standard deviation is close to the theoretical values. Therefore, the Normal model is a good approximation for the sampling distribution.

Find the hourly rate of pay for each of the following jobs: a) Tamara owns a salon and earns R1050 for 6 hours and 15 minutes of work. ​

Answers

Answer:

  ₹168 per hour

Step-by-step explanation:

The hourly rate at which Tamara is paid can be found by dividing her ₹1050 pay by the 6:15 hours that she worked.

Hours

We know there are 60 minutes in an hour, so the fraction of an hour represented by 15 minutes is ...

  (15 min)/(60 min/h) = (15/60) h = 1/4 h = 0.25 h

Added to the 6 whole hours Tamara worked, her pay is for 6.25 hours.

Hourly rate

The pay per hour is found by dividing pay by hours.

  ₹1050/(6.25 h) = ₹168/h

Tamara's hourly rate of pay is ₹168 per hour.

Answers

We can show that these data can be modeled using a linear function in the following manner:

a) We must compute the differences in the number of high school graduates in each year in order to model the data using a linear function. For instance, the difference between the 1993 and 1994 graduation rates is 5,479 - 5,410, or 69. This pattern of differences suggests that a linear function can be used to model the data.

The annual change in the number of graduates serves as the slope for the linear function. The slope, for instance, is 69 between 1993 and 1994 and 76 between 1994 and 1995. The slope for the linear function is, in general, the difference between the number of graduates in successive years, therefore it is the slope between graduates in consecutive years.

b) Y = mx + b, where y is the number of graduates, x is the year, m is the slope, and b is the y-intercept, is the formula for a linear function that represents the data. We need to know the values of m and b in order to calculate the formula for the linear function that describes the data.

We can use the slope between any two consecutive years to get the value of m. For instance, m = 69 since the slope from 1993 to 1994 is 69. The number of graduates in the first year of the data, which is the y-intercept, can be used to determine the value of b.

For instance, if the first year of the data is 1993 and that year had 5,479 graduates, then b = 5,479. Consequently, y = 69x + 5,479 is the equation for the linear function that models the data.

c) Functional notation can be used to indicate the number of high school graduates in 1994. The formula is y = 69x + 5,479, where x is the year and y is the total number of graduates. Therefore, y = 69(1994) + 5,479 = 137,123 is the total number of graduates in 1994. We may enter the numbers of x and b into the formula from section c to obtain y = 69 (1994) + 5,479 = 137,123.

Rank of a matrix can be defined as the maximum number of linearly independent rows (or columns) present in it. The rank of a matrix can be easily calculated using its determinant. Given below are the steps for finding the rank of a matrix using the determinant.

Step 1: Consider a matrix A of order m x n. For a square matrix, m = n.

Step 2: If the determinant of A is non-zero, i.e., |A| ≠ 0, then the rank of the matrix is maximum, i.e., rank of A = min(m, n).

Step 3: If the determinant of A is zero, i.e., |A| = 0, then the rank of the matrix is less than maximum, i.e., rank of A < min(m, n). In this case, the rank can be calculated by eliminating rows (or columns) of A until a non-zero determinant is obtained.

To show that the matrix A has rank 2, we need to show that only two rows or columns are linearly independent. For this, we will consider the determinant of the matrix A. The matrix A can be represented as:

$$\begin{bmatrix}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\end{bmatrix}$$

The determinant of A can be calculated as:

|A| = a11a22a13 + a12a23a21 - a21a12a13 - a11a23a22

If the rank of A is 2, then it implies that two of its rows or columns are linearly independent, which means that at least two of the above determinants must be non-zero. Hence, we can conclude that if one or more of the following determinants is nonzero, then the rank of A is 2:a11a21a12a22|a11a21a13a23a12a22|a12a22a13a23.

1. What is the volume of the solid bounded by the surfaces z = x ^ 3 and z = x ^ 2 + 2y ^ 2 lying directly over the
rectangle 0 lying directly over the rectangle 0≤x≤1,0≤y≤3 ?

Answers

The volume of the solid bounded by the surfaces of the given expression is 3.855 cubic units.

How to calculate volume of solid

To find the volume of the solid bounded by the surfaces

\(z = x^3 and z = x^2 + 2y^2\)

over the rectangle 0≤x≤1,0≤y≤3, set up a triple integral in terms of x, y, and z.

The boundaries of integration for x and y are given by the rectangle 0≤x≤1,0≤y≤3.

For z, the lower boundary is z = x^3 and the upper boundary is

\(z = x^2 + 2y^2\)

Therefore, the triple integral for the volume is:

V = ∫∫∫ dV

where the limits of integration are:

0 ≤ x ≤ 1

0 ≤ y ≤ 3

\(x^3 ≤ z ≤ x^2 + 2y^2\)

Write the volume element dV as dV = dzdydx. then substitute the limits of integration

V = ∫0^1 ∫0^3 ∫x^3^(x^2+2y^2) dzdydx

Integrating with respect to z,

\(V = ∫0^1 ∫0^3 [(x^2 + 2y^2) - x^3] dydx\)

with respect to y

\(V = ∫0^1 [2x^2y + (2/3)y^3 - x^3y]dydx\)

with respect to x,

\(V = ∫0^1 [x^2y^2 + (1/3)x^3y - (1/4)x^4]_0^3 dx\)

\(V = ∫0^1 [(9/4)x^2 + (27/4)x - (1/4)x^4] dx\)

\(V =[(9/5)x^5 + (27/8)x^4 - (1/20)x^5]_0^1\)

V = [(9/5) + (27/8) - (1/20)] - 0

V = 3.855 cubic units

Hence, the volume of the solid bounded by the surfaces is 3.855 cubic units.

\((16+3)-10\div5\times3^2\text{ = 1}\)

Here, we want to simplify the given expression

We shall use the order of simplification for this

The order is PEDMAS

We shall start with the terms in parentheses before we move to the exponents

We have;

\(\begin{gathered} (16+3)-10\div5\times3^2 \\ =\text{ 19-10}\div5\times3^2 \end{gathered}\)

Next is the exponent

\(=\text{ 19-10}\div5\times9\)

The next thing to do is to divide

\(=\text{ 19-}2\times9\)

The next thing to do is to multiply

\(=\text{ 19-18}\)

We then proceed to subtract;

\(=\text{ 19-18 = 1}\)

You are interested in returns to college education. You decide to use log (wage) as the dependent variable, and the main variable of interest is college education (a dummy variable, taking value 1 if an individual is college graduate, and 0, otherwise). (a) Suppose education and experience are important determinants of wage and you decide to add them in the regression. Propose a regression equation to examine the return to college education. Name variables as you wish. Be careful with notation in your answer; that is, be clear with whether you use the population regession function or the sample regression function (or fitted line) (b) Suppose you want to test whether graduates from top 10 universities fare better in the labor market. Propose a regression equation that allows a wage gap between top-10 University graduates (Group 1) and non-top-10 University graduates (Group 2). Define relevant variable(s). Write down the null and alternative hypotheses to test whether the mean log wages differ between the two groups. (c) Propose a regression equation that allows the return to college education to vary with experience. Write down the null and alternative hypotheses to test whether the return to college education vary with experience. (d) Propose a regression equation that allows the return to college education to vary with which university you graduate from (that is, whether one belongs to Group 1 or Group 2). Write down the null and alternative hypotheses to test whether the return to college education differ between the two groups.

Answers

a) Let’s assume the regression equation as follows: log(wage)i = β0 + β1College_edui + β2Experiencei + β3Experiencei^2 + ui

Where:• i is the index of individuals• College_edui is a dummy variable, taking value 1 if an individual is a college graduate, and 0, otherwise•

Experience i is the experience of i th individual• Experiencei^2 captures the squared effect of experience (i.e. the non-linear effect of experience on wage).

b) Let’s denote the variable Top10i to take value 1 if ith individual is graduated from a top 10 university, and 0 otherwise. Then, the regression equation becomes:

log(wage)i = β0 + β1College_edui + β2Top10i + β3(College_edui x Top10i) + ui

Here,β3 is the wage gap between top 10 university graduates (Group 1) and non-top 10 university graduates (Group 2).The null hypothesis (H0): β3 = 0.The alternative hypothesis (H1): β3 ≠ 0.

c) Let the regression equation be:

log(wage)i = β0 + β1College_edui + β2Experiencei + β3Experiencei^2 + β4(College_edui x Experiencei) + ui.

The null hypothesis (H0): β4 = 0 (i.e. the return to college education does not vary with experience).The alternative hypothesis (H1): β4 ≠ 0 (i.e. the return to college education varies with experience).

d) The regression equation allowing the return to college education to vary with which university you graduate from is:

log(wage)i = β0 + β1College_edui + β2Top10i + β3(College_edui x Top10i) + ui.

Here, β3 is the wage gap between the two groups (top 10 universities and non-top 10 universities).

The null hypothesis (H0): β3 = 0 (i.e. the return to college education does not differ between the two groups).

The alternative hypothesis (H1): β3 ≠ 0 (i.e. the return to college education differs between the two groups).

Step-by-step explanation:

The expression 3(-2m + 5) - 6(-4m - 2) can be written in the form am + b. What is the value of a + b?

Answers

Answer: 45

Step-by-step explanation:

3(-2m + 5) -6(-4m - 2) =

-6m + 15 + 24m + 12=

18m + 27

18= a 27= b 27 + 18= 45

The value of the expression a + b is 45.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

First, we can simplify the expression using the distributive property:

3(-2m + 5) - 6(-4m - 2) = -6m + 15 + 24m + 12

Combining like terms, we get:

18m + 27

So, a = 18 and b = 27, which means:

a + b = 18 + 27 = 45

Therefore,

The value of a + b is 45.
