If the formula in the picture below were used to find the r-value of the following data, what would be the value of ¥?

option C

ȳ = 9

Step-by-step explanation:

ȳ (yBar) is used to represent mean value of y

Mean, which is the average score of the population on a given variable

It is represented by = ( Σ Xi ) / N

There are two steps to calculate mean value

sum of all numbers = 3 + 7 + 8 + 11 + 16

                                = 45

    2. Divide by how number of ys (there are 5 numbers)

45 / 5 = 9

So ȳ = 9

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
