Answer:

Follow the steps I did in the explanation.

Step-by-step explanation:

It says to evaluate the equation :-

3.2 = 4/5(b - 5)

3.2 = (4/5 × b) + (4/5 × -5)

3.2 = 4/5b - 4

3.2 + 4 = 4/5b

5/4 × 7.2 = b

9 = b

Hope this helps, thank you :) !!

3.2 = 4/5(b - 5)

3.2 = (4/5 × b) + (4/5 × -5)

3.2 = 4/5b - 4

3.2 + 4 = 4/5b

5/4 × 7.2 = b

9 = b

A researcher found a study relating the value of a car, y, to the age of the car, x. When researchers looked at the association

vredina [299]

Answer: c) About 16% of the variation in value of the car is explained by a linear relationship with the age of the car.

e) The correlation coefficient, r, is 0.397.

Step-by-step explanation:

Given that:

Coefficient of determination (r²) between two variables, age of car (x) and value of car (y) = 0.158

Correlation of determination (r²) of 0.158 = (0.158 × 100% = 15.8% of the variation between the two variables can be explained by the regression line). Hence, about 16% of the variation between age and value of car can be explained by the linear relationship.

Coefficient of correlation (r) = sqrt(r²) = sqrt(0.158) = 0.397

Translate this sentence into an equation. 128 is the product of Donnie's age and 8 . Use the variable d to represent Donnie's ag

Alina [70]

128 = 8d, because the product calls for multiplication to be performed.
