Let X denote the amount of time a book on two-hour reserve is actually checked out, and suppose the cdf is the following. F(x) = 0 x < 0 x2 49 0 ≤ x < 7 1 7 ≤ x Use the cdf to obtain the following. (If necessary, round your answer to four decimal places.) (a) Calculate P(X ≤ 5). (b) Calculate P(4.5 ≤ X ≤ 5). (c) Calculate P(X > 5.5). (d) What is the median checkout duration ? [solve 0.5 = F()]. (e) Obtain the density function f(x). (f) Calculate E(X). (g) Calculate V(X) and ????x. (h) If the borrower is charged an amount h(X) = X2 when checkout duration is X, compute the expected charge E[h(X)].
Using cdf the following results are obtained of the given function F(x) = 0 x < 0 x2 49 0 ≤ x < 7 1 7 ≤ x
P(X ≤ 5) = 0.7813
P(4.5 ≤ X ≤ 5) = 0.0977
P(X > 5.5) = 0.1211
Median checkout duration = 4.6904
f(x) = (2x/49) for 0 ≤ x < 7, and 0 elsewhere
E(X) = 3.5 hours
V(X) = 2.4231 hours^2, and σ_x = 1.5564 hours
E[h(X)] = 10.9375
(a) P(X ≤ 5) = F(5) - F(0) = (5^2/49) - 0 = 0.7813
(b) P(4.5 ≤ X ≤ 5) = F(5) - F(4.5) = (5^2/49) - (4.5^2/49) = 0.0977
(c) P(X > 5.5) = 1 - F(5.5) = 1 - 1 = 0
(d) Solve 0.5 = F(median) for median, which gives median = 4.6904
(e) f(x) = dF(x)/dx = (4x/49) for 0 ≤ x < 7, and 0 elsewhere
(f) E(X) = ∫x f(x) dx = 3.5 hours
(g) V(X) = ∫(x-E(X))^2 f(x) dx = 2.4231 hours^2, and σ_x = sqrt(V(X)) = 1.5564 hours
(h) E[h(X)] = ∫h(x) f(x) dx = 10.9375

The following are properties of the normal curve: A. The high point is located at the value of the mean, C. The total area under the normal curve is 1 (not just to the right), and F. The graph of a normal curve is symmetric.
Explanation:Based on the options provided, the following statements are properties of the normal curve:
A. The high point is located at the value of the mean: In a normal distribution, the high point, which is also the mode, is located at the mean (μ). C. The area under the normal curve to the right of the mean is 1: Possibility of this statement being true is incorrect. The total area under the normal curve, which signifies the total probability, is 1. However, the area to the right or left of the mean equals 0.5 each, achieving the total value of 1. F. The graph of a normal curve is symmetric: Normal distribution graphs are symmetric around the mean. If you draw a line through the mean, the two halves would be mirror images of each other.
Other options do not correctly describe the properties of a normal curve. For instance, normal curves are not skewed right, the high point does not correspond to the standard deviation, and the area under the curve to the right of the mean is not 0.5.

The makers of Brand Z paper towel claim that their brand is twice as strong as Brand X and they use this graph to support their claim. Paper Towel Strength A bar graph titled Paper Towel Strength has Brand on the x-axis, and strength (pounds per inches squared) on the y-axis, from 90 to 100 in increments of 5. Brand X, 100; brand Y, 105; brand z, 110. Do you agree with this claim? Why or why not? a. Yes, because the bar for Brand Z is twice as tall as the bar for Brand X. B. Yes, because the strength of Brand Z is twice that of Brand X. C. No, because paper towel brands are all alike. D. No, because the vertical scale exaggerates the differences between brands.
The correct answer is D. No, because the vertical scale exaggerates the differences between brands.
Step 1: Examine the information presented in the graph. The graph shows the strength of three paper towel brands: Brand X, Brand Y, and Brand Z. The strength values are represented on the y-axis, ranging from 90 to 100 with increments of 5.
Step 2: Compare the strength values of the brands. According to the graph, Brand X has a strength of 100, Brand Y has a strength of 105, and Brand Z has a strength of 110.
Step 3: Evaluate the claim made by the makers of Brand Z. They claim that Brand Z is twice as strong as Brand X.
Step 4: Assess the accuracy of the claim. Based on the actual strength values provided in the graph, Brand Z is not exactly twice as strong as Brand X. The difference in strength between the two brands is only 10 units.
Therefore, the claim made by the makers of Brand Z is not supported by the graph. The graph does not show a clear indication that Brand Z is twice as strong as Brand X. The vertical scale of the graph exaggerates the differences between the brands, leading to a potential misinterpretation of the data. Therefore, it is not valid to agree with the claim based solely on the information provided in the graph.

an auto dealer has 5 different cars and 6 different trucks. how many ways are there to select two vehicles?
The number of possible ways to select two vehicles = 55
Let m represents the number of cars and n represents the number of trucks.
An auto dealer has 5 different cars and 6 different trucks.
This means that m = 5 and n = 6
so, the total number of vehicles (t) would be,
t = m + n
t = 5 + 6
t = 11
Let us assume that p represents the number of possible ways to select two vehicles.
We use the combination formula.
\(^{n}C_r=\frac{n!}{r!(n-r)!}\)
here, n = 11 and r = 2
Using combination formula,
p = \(^{11}C_2\)
p = \(\frac{11!}{2!\times (11-2)!}\)

To generate a list of product names and unit prices ranked by unit price into three categories (1, 2, 3) based on price, you can use a SQL query with the RANK() function.
The highest-priced products will be marked with a 1, the second-highest-priced products with a 2, and so on.
In SQL, you can use the RANK() function along with the ORDER BY clause to rank the products based on their unit prices. The RANK() function assigns a rank to each row in the result set based on the specified ordering criteria. Here's an example SQL query to achieve this:
In this query, products is the name of the table containing the product information. We select the product_name and unit_price columns from the table. The RANK() OVER (ORDER BY unit_price DESC) part ranks the rows based on the unit_price column in descending order, with the highest prices receiving a rank of 1.
The result of this query will include the product names, unit prices, and the assigned price ranks. You can then filter the results based on the price ranks to categorize the products into three categories (1, 2, 3) based on their price rankings.

Two days later, Kelly surveyed the same 13 classmates and found that none of them had been given math homework since she last surveyed them. By how much does the mean of Kelly’s second data set change in comparison with the mean of the data set in her original survey? Explain how to determine the change in the means without calculating the mean of either data set.
Since none of the 13 classmates had been given math homework between the original survey and Kelly's second survey, the sum of the values in the second data set is the same as the sum of the values in the original data set. Therefore, the change in the means can be determined without calculating the mean of either data set by considering the number of data points in each set.
Since both data sets have the same number of data points, the change in the means will be zero. This is because the mean is calculated by dividing the sum of the values by the number of data points, and since the sum of the values is the same in both data sets, the means will also be the same.
In other words, if the mean of the first data set is x, then the sum of the values in the first data set is 13x (since there are 13 classmates), and the sum of the values in the second data set is also 13x (since none of the values have changed). Therefore, the mean of the second data set will also be x, and the change in the means will be zero.

Show that \( \vec{F}=\left(2 x y+z^{3}\right) i+x^{2} j+3 x z^{2} k \) is conservative, find its scalar potential and work done in moving an object in this field from \( (1,-2,1) \) to \( (3,1,4) \) S
A vector field is conservative if its curl is zero. The curl of the vector field F is zero, so F is conservative. The scalar potential of F is given by: f(x, y, z) = x^3 + 2xyz + z^4/4 + C. The work done in moving an object in this field from (1, -2, 1) to (3, 1, 4) is: W = f(3, 1, 4) - f(1, -2, 1) = 70
A vector field is conservative if its curl is zero. The curl of a vector field is a vector that describes how the vector field rotates. If the curl of a vector field is zero, then the vector field does not rotate, and it is said to be conservative.
The curl of the vector field F is given by: curl(F) = (3z^2 - 2y)i + (2x - 3z)j
The curl of F is zero, so F is conservative.
The scalar potential of a conservative vector field is a scalar function that has the property that its gradient is equal to the vector field. In other words, F = ∇f.
The scalar potential of F is given by:
f(x, y, z) = x^3 + 2xyz + z^4/4 + C
The work done in moving an object in a conservative field from one point to another is equal to the change in the scalar potential between the two points. In this case, the work done in moving an object from (1, -2, 1) to (3, 1, 4) is:
W = f(3, 1, 4) - f(1, -2, 1) = 70
