Correlation coefficients. if the formula were used to find the r-value of the following data, what would be the value of y?

a. 5
b. 9.
c. 7
d. 3

Step-by-step explanation:

According to the problem, we have to find which refers to the mean of y-values.

So, we just have to find the mean:

Therefore, the right answer is C.

Remember that the mean is defined as the quotient betwene the sum of all values, and the total number of them. In this case, the sum is 35 and the total number is 5.

i believe that the slope of the line is -5

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
