A retail store served 669 customers in October, and there were 27 complaints during that month. What is the experimental probability that a customer complains? Give your answer as a percentage, rounded to the nearest whole percent.

Probability that a customer complains in percentage = 4% (Approx)

Step-by-step explanation:

Given:

Total number of customers = 669

Total number of complaints = 27

Find:

Probability that a customer complains

Computation:

Probability that a customer complains = 27 / 669

Probability that a customer complains in percentage = [27 / 669]100

Probability that a customer complains in percentage = [0.040358]100

Probability that a customer complains in percentage = 4.0358%

Probability that a customer complains in percentage = 4% (Approx)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
