To solve for P(QIR) we use the formula:
P(QIR)=[P(Q∩R)]/P(R)
But from the diagram:
P(Q∩R)=3/22
P(R)=7/22
hence
P(QIR)=3/22÷7/22=3/7

skad [1K]

Answer:

Input variable x: Number of classes he attends.

Output variable y: Monthly cost

Slope: Cost per class, of $2

y-intercept: Membership fee, of $25.

Function: y = 2x + 25

Step-by-step explanation:

This situation can be represented by a function is the following format:

y = mx + b

In which y is the monthly cost(output), m is the cost per class(slope), x is the number of classes he attends(input) and b is the membership fee(y-intercept).

We have that:

There is a membership fee of $25 per month and a fee of $2 per workout class he attends.

This means that b = 25, m = 2. So

y = 2x + 25
