In the simple linear regression model, the regression slope: (a) indicates by how many units y increases, given a one-unit increase in x.(b) when multiplied with the explanatory variable will give you the predicted y.(c) indicates by how many percent y increases, given a one percent increase in x.(d) represents the elasticity of y on x.

(A) indicates by how many units Y increases, given a one-unit increase in X.

Step-by-step explanation:

The form for simple linear regression model for outcome y which is a function of predictor x is:

y = β₀ + β₁x + ε  

For this model, β₀ is population parameter which corresponds to intercept and β₁ is the true population slope coefficient which is defined as predicted increase in the y for  a unit increase in the x.

Hence option (A) indicates by how many units Y increases, given a one-unit increase in X  is correct.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
