The Median and IQR are most appropriate to describe the measures of center and variability of distribution. The histogram depicts the distribution of time is positively skewed. So, option(b) is right one.

We have a graph present in above figure, which showes the amount of time in hours spent on homework per week for a sample of students. We have to select correct measures of center and variability. The graph is a histogram. From the graph we can see that the data is positively skewed. Now for skewed distribution we prefer median over mean as mean is more sensitive to the outliers. As the data(time) is in ratio scale we can use any of the measures of dispersion; but for skewed distribution IQR is preferred because of its robustness. In a word both median and IQR can handle outliers. Thus the appropriate answer is Median and IQR, option (c).

Step-by-step explanation:

Approximately 17 students who took the optional class passed their driver's test.

Let's solve this problem step by step.

We are given the following information:

28 out of 75 students who took the optional class passed their driver's test.

8 out of 15 students overall passed their driver's test.

3 out of 5 students took the optional class.

To find the number of students who took the optional class and passed, we need to calculate the intersection of these two groups.

First, let's calculate the total number of students who took the optional class:

Total students who took the optional class = (3/5) \(\times\) Total number of students

Total students who took the optional class = (3/5) \(\times\) 75 = 45

Now, let's calculate the total number of students who passed their driver's test:

Total students who passed their driver's test = (8/15) \(\times\) Total number of students

Total students who passed their driver's test = (8/15) \(\times\) 75 = 40

Next, let's find the number of students who both took the optional class and passed their driver's test.

This can be found by taking the intersection of the two groups:

Number of students who took the optional class and passed = (28/75) \(\times\)Total students who took the optional class

Number of students who took the optional class and passed = (28/75) \(\times\)45 = 16.8 (approximated to the nearest whole number).

Therefore, approximately 17 students who took the optional class passed their driver's test.

It's important to note that since we're dealing with whole numbers, the approximated answer is 17, as we cannot have a fraction of a student.

The area of one of the bases of the hexagonal prism is approximately 7.39 units^2.

To solve this problem, we can use the formula for the volume of a hexagonal prism:

V = (3√3/2) * a^2 * h

where V is the volume, a is the length of one side of the hexagonal base, and h is the height of the prism.

We are given that the height of the prism is 4 units and the volume is 98 units^3. Plugging these values into the formula, we can solve for the length of one side of the base:

98 = (3√3/2) * a^2 * 4
a^2 = 98 / (12√3)
a ≈ 2.95

Now that we know the length of one side of the base, we can find the area of the hexagon by using the formula:

A = (3√3/2) * a^2

where A is the area of one of the bases. Plugging in the value we found for a, we get:

A = (3√3/2) * (2.95)^2
A ≈ 7.39

Therefore, the area of one of the bases of the hexagonal prism is approximately 7.39 units^2.

Answer:

y = 2/5 x - 3.1

Step-by-step explanation:

Slope of the line passing through the points (0, 2) and (5, 4) = (4-2)/(5 - 0) = 2/5

Since required line is parallel to the line passing through the points (0, 2) and (5, 4).

Therefore, slope of required line (m) = 2/5

Required line passes through the point ( 4, - 1.5)

Therefore equation of line in slope point form is given as.

y - (-1.5) = m(x-4)

y + 1.5 = 2/5(x - 4)

5y + 7.5 = 2x - 8

5y = 2x - 8 - 7.5

5y = 2x - 15.5

y = 2/5 x - 3.1

A scientist can use bootstrap analysis to estimate the strength of evidence that a particular node in a phylogeny exists.

Bootstrap analysis is a statistical method used to determine the reliability and robustness of phylogenetic trees' topologies. In bootstrap analysis, a series of random resampling with replacement is used to assess how well the observed data fit the phylogenetic hypothesis.

Bootstrap values range from 0 to 100 and reflect the proportion of times that a particular node or branch occurs in the bootstrap replicate trees. Bootstrap values greater than 70% are usually considered strong evidence that a particular node or branch exists in the phylogenetic tree.

Bootstrap analysis is an important tool for understanding the reliability of phylogenetic trees and the evolutionary relationships among organisms.

(a) X: -2 | -1 |  0 |  1 |  2 |  3 |  4 Y:  5  |  0 | -3 | -4 | -3 |  0 |  5 (b) The values of x when y = 1 are approximately x = -0.37 and x = 2.37.

For part (a), you have correctly filled in the missing values in the table for the function y = x^2 - 2x - 3. The completed table is as follows:

X: -2 | -1 |  0 |  1 |  2 |  3 |  4
Y:  5  |  0 | -3 | -4 | -3 |  0 |  5

For part (b) i), since I do not have access to the graphs, I cannot identify which of the three curves matches the function y = x^2 - 2x - 3. However, you can verify this yourself by looking for a curve that passes through the points listed in the table.

For part (b) ii), you have correctly estimated the value of y when x = 2.5 as -1.75.

Now, let's address part (b) iii). To find the values of x when y = 1, we need to solve the equation x^2 - 2x - 3 = 1. First, rewrite the equation as x^2 - 2x - 4 = 0. You can solve this quadratic equation using various methods such as factoring, completing the square, or using the quadratic formula. In this case, the quadratic formula is most convenient:

x = [-(-2) ± √((-2)^2 - 4(1)(-4))] / [2(1)]

x = [2 ± √(20)] / 2

x ≈ -0.37 or x ≈ 2.37

So, the values of x when y = 1 are approximately x = -0.37 and x = 2.37.

Answer:

It is $3.00 per hour

Step-by-step explanation:

Let C be the total charge and t be the rental time in hours.

C = ht + 43

Plugging the given values into the equation, we get:

64 = 7h + 43

7h = 21

h = 3

The hourly fee is $3.00 per hour.

The hourly fee for the rototiller is 3 dollars.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Given that, the rental company charged an initial fee of $43 with an additional fee per hour.

They paid $64 after renting the rototiller for 7 hours

Here, h represents the hourly fee

Now, 43+7h=64

7h=64-43

7h=21

h=$3

Therefore, the hourly fee for the rototiller is 3 dollars.

1 have only one real fifth root.And the root is 1

The fifth root of a number is the number that would have to be multiplied by itself 5 times to get the original number. For example, the fifth root of 243 is 3 as 3 x 3 x 3 x 3 x 3 is 243. Another example is fifth root of 32 which is 2. i.e 2×2×2×2×2 = 32

Unlike the even roots like square root fourth root and 6 root that has 2 real roots as solutions, e.g fourth root of 256 is ± 4. This mean multiplying -4 in four places and + 4 in four places will give 256, odd roots like fifth root, cube root only have one root.

A type I error refers to when we are are engaged in a hypothesis test and end up rejecting the Null hypothesis even though it is true.

If we are in hypothesis tests and the probability of a type 1 error decreases, then it means that the probability of us correctly rejecting the null hypothesis when it is false increases.

It also means that the probability of us correctly accepting the null hypothesis when it is true increases as well.

This can further be said as the probability of us accepting the null hypothsis when it is false, decreases. There are therefore less chances of us incorrectly accepting the null hypothesis.
