The marketing department of a sports supply store wants to estimate the percentage of adults in the town who belong to a gym. Wh
Oxana [17]

Since we want to estimate the percentage of adults in the town who belong to a gym. We should take a random sample from the town itself because a store’s adult customers, or their friends, or first 20 customers every day for one week, or adults at the local park might not represent better sample for survey.

Therefore, Take a random sample of adults in the town, and ask each person whether he or she belongs to a gym. Calculate the percentage of the total who say “yes.”

Hence, option D describes a method that will help the marketing department accurately estimate this percentage.

Answer:

x = - 1

Step-by-step explanation:

Given

4x = x^2 - 5               Transfer 4x to the right side.

Solution

x^2 - 4x - 5 = 0          Factor

(x - 5)(x + 1)

You want the negative solution. That means that the middle sign must be plus.

x + 1 = 0                   Subtract 10 from both sides

x = - 1                       Ten on the left disappears by the subtraction process.

Is that correct?

4x = x^2 - 5

x = - 10

4*(-1) = (-1)^2 - 5

-4  = ? 1 - 5

-4 = - 4

and it does work.
