Step-by-step explanation:

The diameter of the circle is 3 miles.

Given that, a circle with circumference of 9.42 miles, we need to find diameter of the circle,

Circumference = π × diameter

9.42 = 3.14 × diameter

Diameter = 9.42 / 3.14

Diameter = 3

Hence, the diameter of the circle is 3 miles.

The height of the cone that has a volume of 100 cubic inches is calculated to the nearest tenth as: h ≈ 6.0 in.

To find the height of the cone, recall he formula for finding the volume of a cone which is expressed as:

Volume (V) = 1/3πr²h

Given the following:

Volume = 100 in.³

Radius (r) = 8/2 = 4 in.

Plug in the values:

100 = 1/3 * 3.14 * 4² * h

100 = 16.7 * h

Divide both sides by 16.7

100/16.7 = h [Division property of equality][

h ≈ 6.0 in.

On adding the provided equations, 4x +7y= 17 and 9x + 13y = 46 the resultant equation we will be getting is 13x + 20y = 63.

In order to perform addition of two equations together, we are needed to add the left-hand side of each equation and the right-hand side of each equation separately. This gives us:

(4x + 7y) + (9x + 13y) = 17 + 46

Combining like terms on both the sides, we will be getting ,

It's important to remember that using the binomial approximation assumes a large population size, which may not be the case here.

To answer your questions, we will use R commands to calculate the probabilities.

(a) To find the probability that exactly 6 of the students will be full-time, we can use the "dhyper" function in R. The parameters are x = 6, m = 30 (number of full-time students), n = 20 (number of part-time students), and k = 10 (sample size).

R command:
```R
dhyper(x = 6, m = 30, n = 20, k = 10)
```

(b) To find the probability that at most 8 of the students will be full-time, we can use the "phyper" function in R, which calculates the cumulative probability. We need to calculate P(X ≤ 8).

R command:
```R
phyper(q = 8, m = 30, n = 20, k = 10)
```

(c) To use the binomial approximation, we can use the "dbinom" function in R with p = 0.6 (probability of full-time student) and n = 10 (sample size). We want to calculate P(X = 6).

R command:
```R
dbinom(x = 6, size = 10, prob = 0.6)
```

Compare this result with the answer in part (a). If the difference is relatively small, it's appropriate to use the binomial approximation in this scenario.

The mass of African elephant is 30 times of Silverback gorilla, so, the value of m is found to be 30 which is an integer.

The mass of an African elephant is about 6 x 10⁶ grams. The mass of a silverback gorilla is about 2 x 10⁵ grams. Solution using unitary method,

Mass of elephant = 6 x 10⁶ grams

Mass of gorilla = 2 x 10⁵ grams

Let us say that m gorillas are weighting equal to one elephant. We need to find the value of m, such that,

6 x 10⁶ = m x 2 x 10⁵

Dividing both sides by 2 x 10⁵, we get:

m = 6 x 10⁶ / 2 x 10⁵

m  = 30

The dimensions of the new rectangle are 35 and 77.

The height of the ball after 4 seconds if it was kicked from the top of a 25 foot tall hill at 72 feet per second is 57 feet.

We are given that the height of the ball after t seconds is given by the polynomial −16[tex]t^{2}[/tex] + vt + h. We need to find the height of the ball after 4 seconds if it was kicked from the top of a 25 foot tall hill at 72 feet per second.

Substituting v = 72 and h = 25 in the given polynomial, we get:

-16[tex]t^{2}[/tex] + 72t + 25

To find the height of the ball after 4 seconds, we substitute t = 4 in the above polynomial:

-16[tex](4)^{2}[/tex] + 72(4) + 25 = -256 + 288 + 25 = 57

The probability that their first child will not roll its tongue and will have the normal number of fingers is 25%.

To determine the probability that their first child will not roll its tongue and will have the normal number of fingers, we need to know the probability of each event separately and then multiply them together.

Assuming that rolling the tongue is a dominant trait and the father is homozygous recessive for the finger trait, the probabilities are:

The probability that the first child will not roll its tongue is 25% (or 0.25), as both parents are heterozygous and carry the dominant allele.

The probability that the first child will have the normal number of fingers is 100% (or 1), as the father is homozygous recessive for the trait and will only pass on the normal allele.

Multiplying the two probabilities together, we get

0.25 x 1 = 0.25 or 25%

Therefore, there is probability of 25% that their first child will have the normal number of fingers and will not roll its tongue.

the statement that is true is that Desmond's aquarium has a higher concentration of chemical solution than Megan's aquarium, even though they added the same amount of water and chemical solution.

How to solve the question?

To compare the chemical concentration of the two aquariums, we need to convert the amount of chemical added to a common unit of measurement. Let's convert Megan's chemical solution to mL per 2 gallons, which is equivalent to 7.57 L per 3785.41 mL of water. This means that Megan added 7.57 mL of the chemical solution for every 2 gallons of water in her aquarium.

Desmond added 8 mL of the chemical solution for every 2 gallons of water in his aquarium. So, both Megan and Desmond added the same amount of chemical to their aquariums.

However, the concentration of the chemical in the water would be different since Megan added the chemical at a higher rate than Desmond. Megan added 7.57 mL of chemical per 2 gallons of water, while Desmond added 8 mL of chemical per 2 gallons of water. This means that the concentration of the chemical in Megan's aquarium would be lower than that in Desmond's aquarium.

Therefore, the statement that is true is that Desmond's aquarium has a higher concentration of chemical solution than Megan's aquarium, even though they added the same amount of water and chemical solution.

The boys sold 200 tickets and the girls sold 230 tickets.

Let's represent the number of tickets boys sold as x.

Then, the number of tickets girls sold would be 15% more than the number of tickets boys sold, which is 1.15x.

As per the percent rule:

Together, the total number of tickets sold is given as 430:

x + 1.15x = 430

Combining like terms, we get:

2.15x = 430

A box-and-whisker plot, also known as a box plot, is a graphical representation of a data set that shows the distribution of the data and provides information about its central tendency and variability.

To construct a box-and-whisker plot from the given line plot, we need to find the following five data points:

The minimum value, which is the smallest number of miles Habib hiked in the past 18 days.

The first quartile (Q1), which is  median of  lower half of  data set.

The third quartile (Q3), which is the median of the upper half of the data set.

The maximum value, which is the largest number of miles Habib hiked in the past 18 days.

Based on the line plot, we can estimate the five data points as follows:

The minimum value appears to be 1 miles.

The first quartile appears to be around 6 miles, which is the median of the data points from day 1 to day 9.

The median appears to be around 9 miles, which is the middle value of the entire data set.

Answer:

a. 1.26

b. 0.1038

Step-by-step explanation:

The p-value is 1.0000 (rounded to four decimal places). This means that we fail to reject the null hypothesis, which in this case would be that the population mean is equal to the sample mean of 26.2.

To find the test statistic, we need to use the formula:

test statistic = (sample mean - population mean) / (standard deviation / square root of sample size)

Since the population standard deviation is given as 6, we can plug in the values:

test statistic = (26.2 - population mean) / (6 / √40)

To find the population mean, we can use the fact that the sample mean is an unbiased estimator of the population mean, so:

population mean = sample mean = 26.2

Plugging in the values, we get:

test statistic = (26.2 - 26.2) / (6 / √40) = 0

The test statistic is 0.

To find the p-value, we need to use a t-distribution table or calculator. Since we have a sample size of 40, we can use the t-distribution with 39 degrees of freedom.

Using a calculator or table, we can find that the area to the right of 0 (since the test statistic is 0) is 0.5. Since this is a two-tailed test, we need to double this value to get the p-value:

p-value = 2 * 0.5 = 1.0000
