1. r closest to 1: Figure 4

2. Least signs of linear relationship: Figure 1

3. r equal to -1: Figure 3

Step-by-step explanation:

Correlation is the link between two things or variables.

The scatter plots can be used to determine the correlation values for given sets of data.

If both values are increasing, then the correlation is positive

If one value is increasing and the other is decreasing then the correlation is negative

So,

In the given pictures

Figure 4 has the correlation coefficient closest to 1 as both values are increasing but the data points are not in a straight line so r will be close to 1.

Figure 3 has the correlation coefficient equal to one as one value is increasing and the other is decreasing. And the points are in a straight line so r will be equal to one.

As the data points in Figure 1 are more scattered so there will be no relationship between two quantities.

So, the answers are as follows

1. r closest to 1: Figure 4

2. Least signs of linear relationship: Figure 1

3. r equal to -1: Figure 3

How do you solve –5n + 2.75 = –28.75 with solving steps

Alexxandr [17]

Answer:

n = 6.30

Step-by-step explanation:

-5n+2.75 -2.75= -28.75 - 2.75

-5n =-31.50

divide both sides by -5

-5n/-5 = -31.50/ -5

the -5's cancel out . . .n = 6.30

when you divide a negative by a negative gives you a positive

5 over 4 n plus 5 equals 20

VashaNatasha [74]

1.) Exclude the restricted values of n
2.) Move constant to the right side and change its sign
3.) Subtract the numbers
4.) Simplify the equation using cross-multiplication
5.) To get the variable on the left side, switch the sides of the equation
6.) Divide both sides of the equation by 60
7.) Reduce the fraction with 5
8.) If any solution equals to the restricted value, exclude it
Your answer will be n=1over

 (6 pts) The average age of CEOs is 56 years. Assume the variable is normally distributed. If the SD is four years, find the pr

Alenkinab [10]

Answer:

The probability that the age of a randomly selected CEO will be between 50 and 55 years old is 0.334.

Step-by-step explanation:

We have a normal distribution with mean=56 years and s.d.=4 years.

We have to calculate the probability that a randomly selected CEO have an age between 50 and 55.

We have to calculate the z-value for 50 and 55.

For x=50:

$z=\frac{x-\mu}{\sigma}=\frac{50-56}{4}=\frac{-6}{4}= -1.5$

For x=55:

$z=\frac{x-\mu}{\sigma}=\frac{55-56}{4}=\frac{-1}{4}=-0.25$

The probability of being between 50 and 55 years is equal to the difference between the probability of being under 55 years and the probability of being under 50 years:

$P(50$
