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.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
