Add 3 to both sides:

-x = 8

Multiply both sides by -1:

x = -8

The answer is:

(-8,3)

At a certain college, 28% of the students major in engineering, 18% play club sports, and 8% both major in engineering and play

Alex

Answers: 0.286

Explanation:

Let E → major in Engineering

Let S → Play club sports

P (E) = 28% = 0.28

P (S) = 18% = 0.18

P (E ∩ S ) = 8% = 0.08

Probability of student plays club sports given majoring in engineering,

P ( S | E ) = P (E ∩ S ) ÷ P (E) = 0.08 ÷ 0.28 = 0.286
