Answer:

<h2> B. 0.65 </h2>

Step-by-step explanation:

The options to this question are

A. 0.55

B. 0.65

C. 0.35

D. 0.45

The correlation coefficient is a statistical measure of the realtionship between variables in a study, this measure is about how strong are realted those variables. The correlation could be strong or weak, could be negative or positive.

The range or interval where the correlation coefficent falls is from -1 to 1. If the coefficient is outside this interval, there's an error in the data set.

Now, if the coefficient is zero, it means there's no correlation between variables. But, if the coefficient is near to 1, it means the correlation is positive and strong.

Therefore, in this case, the right answer is B. 0.65, because it's the closest value to 1.

A. 0.55

B. 0.65

C. 0.35

D. 0.45

0.65  represents the strongest correlation.

Answer: Option B.

<u>Explanation:</u>

In statistics, correlation or dependence is any measurable relationship, regardless of whether causal or not, between two arbitrary factors or bivariate information. In the broadest sense connection is any measurable affiliation, however it normally alludes to how much a couple of factors are straightly related.

For two factors, a statistical correlation is estimated by the utilization of a Correlation Coefficient, spoke to by the image (r), which is a solitary number that depicts the level of connection between two factors.

A cylinder and a come have the same volume. The cylinder has a radius of 2 inches and a height of 3 inches. The cone has radius
MrRissso [65]

Answer: 4in

Step-by-step explanation:

Volume of a cylinder = πR²H

Volume of a cone = 1/3πr²h

πR²H = 1/3πr²h

π is very common so it could be cancelled, so the equation now becomes

R²H = 1/3r²h

3R²H = r²h

Now substitute for the values

h = 3 x 2² x 3

--------------

3²

= 9 x 4/9

= 4in.

Therefore, the height of the cone

h = 4in.

Use the elimination method to solve the system of equations. Choose the
IRINA_888 [86]

Answer: x=6

Y=6

Step-by-step explanation:

Using the elimination method

3x+5y=48.....equ1

-3x+5y=12......equ2

Add equation 1 &2

3x+5y=48

+

-3x+5y=12

Answer =

10y=60

Y=60/10

Y=6

Substitute for y in equation 1

3x+5y=48

3x+5(6)=48

3x+30=48

3x=48-30

3x=18

X=18/3

X=6

Therefore,

X= 6

Y= 6
