Step-by-step explanation:
−12x+14=−10x−8
Step 1: Add 10x to both sides.
−12x+14+10x=−10x−8+10x
−2x+14=−8
Step 2: Subtract 14 from both sides.
−2x+14−14=−8−14
−2x=−22
Step 3: Divide both sides by -2.
−2x
−2
=
−22

Answer:
A sample of 752 should be taken.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
The margin of error is of:
90% confidence level
So , z is the value of Z that has a p-value of , so .
No preliminary sample is taken
This means that
How large should the sample be to be 90% sure that the estimate is within .03 of the population proportion?
This is n for which M = 0.03. So
Rounding up:
A sample of 752 should be taken.
