Divide 10 by 2, gives you 5. multiply that by 5, 5*5= 25 then multiply that by 3.14. 25*3.14, gives you 78.5 hope this helped :D

If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²
Then you do r * π *r which would be 78.5. so C is your answer.

In one study, it was found that the correlation coefficient between two variables is -0.98. Which statement is true?
Vadim26 [7]

<u>Answer- </u>D. There is a strong negative association between the variables

<u>Solution-</u>

Properties of Correlation Coefficient

1-  Its value ranges between -1 and 1.

2- The greater the absolute value of correlation coefficient, the stronger is the linear relationship.

3- The weakest linear relationship is indicated by a correlation coefficient equal to 0.

4- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.

5- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.

As the given correlation coefficient is -0.98 (-ve), whose absolute value is 0.98 (closer to 1)

So there is a strong negative association between the variables.

Answer: ∠REA = 53°

Step-by-step explanation:

Since ∠BEA = 71°, set both angle measures equal to that.

2x + 5x + 8 = 71

Solve for x. First, combine like terms:

7x + 8 = 71

Then, subtract 8 from both sides:

7x = 63

Divide both sides by 7:

x = 9

Now, plug x into ∠REA:

∠REA = 5x + 8

∠REA = 5(9) + 8

∠REA = 45 + 8

∠REA = 53°

Hope this helps!
