Determine whether the sample may be biased. Explain. An automobile dealer surveys its customers to determine their level of satisfaction with the services provided at the dealership. The sample is chosen from a list of customers who gave the dealership an e-mail address.
Select one:
a. The sample is not biased. It is a random sample.
b. The sample is biased. Not all customers of the automobile dealership have an e-mail address.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
