We have a negative relationship between number of drinks consumed and number of marks in a driving test. One individual scores 3 on number of drinks consumed, another individual scores 5 on number of drinks consumed. What will be their respective scores on the driving test if the intercept is 18 and the slope -3?

Driver 1 score: 9

Driver 2 score: 3

Step-by-step explanation:

We are given the following in the question:

The number of marks scored on a driving test are y(x) is a dependent variable and the number of drinks taken by the driver is the independent variable(x).

Slope, m = -3

y-intercept,c = 18

Then, we can write the regression equation as:

Driver 1 consumed 3 drinks.

We put x = 3 in the regression equation.

Thus, the predicted driving 1 score for driver 1 is

Driver 1 predicted score is 9.

Driver 2 consumed 5 drinks.

We put x = 5 in the regression equation.

Thus, the predicted driving 2 score for driver 2 is

Driver 2 predicted score is 3.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
