a)   there is a strong positive correlation between the variables based on the given correlation coefficient and critical value

To interpret correlation values, the Table of Critical Values must be used. In this case, the correlation be reasonable to conclude that the data come from a r X. Table of critical values Sample Size, n Critical Value Sample Size, n Critical Value 5 0.880 16 0.941 6 0.888 17 0.944 7 0.898 18 0.946 8 0.906 19 0.949 9 0.912 20 0.951 10 0.918 21 0.952 11 0.923 22 0.954 12 0.928 23 0.956 13 0.932 24 0.957 14 0.935 25 0.959 15 0.939 30 0.960. The correlation coefficient is found between -1 and 1. Correlation values near 1 indicate a strong positive correlation, while those near -1 indicate a strong negative correlation. Correlation values near zero, on the other hand, indicate no correlation between the variables. In this case, we can interpret that the correlation is significant because it falls outside of the range of -0.880 and 0.880. We can see that the correlation value of 0.918 is higher than the critical value of 0.880 for the sample size of 10 from the given table of critical values. As a result, it can be concluded that there is a strong positive correlation between the variables based on the given correlation coefficient and critical value.

Step-by-step explanation:

Corsica adds 3/32 = 0.09375 ounces of water to the bucket per second.

To find how many ounces of water are added to the bucket per second, we need to rearrange the given equation to solve for the rate of change of the water, which is the change in the amount of water per unit of time.

Starting with:

3W = 32S

We can divide both sides by S:

3W/S = 32

Now we can see that the left-hand side represents the amount of water (in ounces) added per second, since W/S is the rate of change of the water with respect to time.

Therefore, we can conclude that Corsica adds 3/32 = 0.09375 ounces of water to the bucket per second.

The distance between the two points from the geometrical formula for that purpose is 6.2.

The distance between two points in geometry is the length of the straight line segment that connects the two points. It is calculated using the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two legs is equal to the square of the length of the hypotenuse.

Using the formula;

d= √(x2 - x1)^2 + (y2 - y1)^2

d = √(7.5 - 3)^2 + (6.25 - 2)^2

d = √20.25 + 18.06

It depends on the specific composite figure. In general, the perimeter of a composite figure is not always equal to the sum of the perimeters of the individual figures that make it up.

However, in some cases, it is possible to calculate the perimeter of a composite figure by adding the perimeters of the individual figures and subtracting the lengths of any shared sides.

For example, if a composite figure is made up of two rectangles that share a side, then the perimeter of the composite figure is equal to the sum of the perimeters of the two rectangles minus the length of the shared side.

In other cases, such as when a composite figure has curved sides or irregular shapes, the perimeter cannot be calculated simply by adding the perimeters of the individual figures.

Step-by-step explanation:

The probability that a red ball was selected more than 20 times when 25 balls are randomly selected from the jar with replacement is 0.037.

Given that a jar contains 30 red balls and 20 white balls. Also, 25 balls are randomly selected from the jar with replacements. We need to find the probability that a red ball was selected more than 20 times.

The binomial probability distribution function can be represented as follows:
[tex]P(X = k) = \ ^nC_k . p^k . q^{(n-k)}[/tex]
where n is the number of trials, k is the number of successes,

p is the probability of success,

q = 1 - p is the probability of failure.
Here, the probability of selecting a red ball is 30/50 = 3/5.

So, the probability of selecting a white ball is 2/5.
Here, we have n = 25 trials, p = 3/5, q = 2/5.

Let X be the number of times a red ball is selected. Then we need to find P(X > 20).
So, P(X > 20) = 1 - P(X ≤ 20)
= 1 - Σ P(X = k), k = 0 to 20
[tex]= 1 - \sum \ ^nC_k . p^k . q^{(n-k)}[/tex], k = 0 to 20
[tex]P(X = k) = \ ^nC_k . p^k . q^{(n-k)}[/tex]

[tex]P(X > 20) = 1 - \sum \ ^nC_k . p^k . q^{(n-k)}[/tex], k = 0 to 20

= [tex]1 - { \ ^nC_0 . p^0 . q^{(n-0)} + \ ^nC_1 . p^1 . q^{(n-1)} + \ ^nC_2 . p^2 . q^{(n-2)} + ... + \ ^nC_{20} . p^{20} . q^{(n-20)}}[/tex]
= 1 - {1 . (3/5)^0 . (2/5)^25 + 25 . (3/5)^1 . (2/5)^24 + 300 . (3/5)^2 . (2/5)^23 + ... + 1.623 x 10^10 . (3/5)^20 . (2/5)^5}
= 1 - 0.963
= 0.037

Therefore, the probability that a red ball was selected more than 20 times when 25 balls are randomly selected from the jar with replacement is 0.037.

I think it has an area of 4 and a perimeter of 8, i'm not totally sure but I thought I'd try to help

Answer:

area:4

perimeter:8ft

Step-by-step explanation:

when doing the area, you have to MULTIPLY the length by the width. For example, length:5ft width:7ft so to find the area you have to multiply both and get the answer of 35. so for the sum you have is 2 × 2 = 4

for perimeter, you have to ADD all the sides so if you have a square with all sides of 4 you add them all up which = 16. so for your sum, add them all up = 8ft

Answer:

37 customers preferred cake.

Step-by-step explanation:

A percentage is a ratio or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

To find out how many customers preferred cake, we need to multiply the total number of customers (105) by the percentage of customers who preferred cake (35%):

(35% = 0.35)

Rounding this to the nearest whole number gives us 37. Therefore, approximately 37 customers preferred cake.

Answer:

35% of 105 is 36.75. ( Rounded up 37). So 37 customers preferred cake the most

Answer:

identify a relationship among Tn,Sn and Sn-1 where n>1

The population of the town after 12 years Aand in 24 years will be approximately 34,461 and 79,171 respectively.

If the population doubles every 10 years, then we can use the formula for exponential growth to find the population after a certain number of years:

P = P₀ x 2^(t/T)

where:

P₀ = initial population = 15,000

P = population after t years

T = doubling time = 10 years

t = number of years

Using this formula, we can find the population after 12 years:

P = 15,000 × 2^(12/10)

P = 34,461

Therefore, the population of the town after 12 years will be approximately 34,461.

Similarly, we can find the population after 24 years:

P = 15,000 ×  2^(24/10)

P = 79,171

Therefore, the population of the town after 24 years will be approximately 79,171.

Answer: 10

Step-by-step explanation:

Let L be the length of the rectangle, and W be the width.

From the problem, we know that:

The perimeter of the rectangle is 72, which means that:

2(L + W) = 72

L + W = 36

The width is 4 less than 3 times the length:

W = 3L - 4

Substituting W = 3L - 4 into the first equation, we get:

L + 3L - 4 = 36

4L = 40

L = 10

Therefore, the length of the rectangle is 10. Answer:  10

The width of the rectangle is 3/2 cm and the length is 17 cm.

The formula for the area of a rectangle is A = L x W, where A is the area, L is the length, and W is the width. To solve this problem, we can rearrange the formula to solve for W: W = A / L. In this case, A = 6 cm and L = 2W + 11 cm. Substituting these values, we get W = 6 / (2W + 11). We can solve this equation by dividing both sides by 2W to get 1/W = 6 / (2W + 11) * 1/2W. Simplifying, we get 1/W = 3 / (11 + 2W). Subtracting 3/11 from both sides, we get -2/11 W = -3/11. Finally, we can solve for W by dividing both sides by -2/11 to get W = 3/2 cm.

Therefore, the width of the rectangle is 3/2 cm, and the length of the rectangle is 2W + 11 = 11 + 6 = 17 cm.

Answer: 0.2 square meters.

Step-by-step explanation:

We are given the equation:

3600b² = hw

We need to find the value of b, given that h = 168 cm and w = 60 kg.

First, we need to convert the height from centimeters to meters:

h = 168 cm = 1.68 m

Substituting the given values:

3600b² = (1.68)(60)

3600b² = 100.8

b² = 100.8/3600

b² = 0.028

Taking the square root of both sides:

b = √0.028

b ≈ 0.167

Rounding to the nearest tenth:

b ≈ 0.2

Therefore, the body surface area of a person who is 168 centimeters tall and weighs 60 kilograms is about 0.2 square meters.

Answer: The correct answer is:

The y-intercept is 3.79, which means a student with no absences is predicted to have a GPA of 3.79.

Explanation:

To determine the relationship between the number of absences and the GPA, the student can use linear regression analysis. The regression line can be obtained using software such as Excel or R. The y-intercept of the regression line represents the predicted value of the response variable (GPA) when the predictor variable (number of absences) is zero.

Using technology, the y-intercept for this data set is found to be 3.79. This means that a student with zero absences is predicted to have a GPA of 3.79. Therefore, the correct answer is that the y-intercept is 3.79 and it does make sense to interpret it in this context.

To find the multiplication equation that shows how the denominators of 3/4 and 1/2 are related, we can simply multiply the two denominators together:

3/4 x 1/2 = 3/8

Therefore, the denominators are related by the equation 4 x 2 = 8.

To write 1/2 as an equivalent fraction with a denominator of 4, we need to multiply both the numerator and denominator by the same factor that will transform the denominator of 2 to a denominator of 4.

Using the multiplication equation we found earlier, we can see that we need to multiply both the numerator and denominator of 1/2 by 2 (since 2 x 2 = 4). This gives us:

1/2 x 2/2 = 2/4

Therefore, 1/2 can be written as an equivalent fraction with a denominator of 4 as 2/4.
