Answer:

2x - 2y

Step-by-step explanation:

P = 7x + 2y

P =a + b + c

7x + 2y = 2x + y +3x - 5y + c

7x + 2y - 5x - 4y

= 2x - 2y

A city planner wants to estimate, with a 99% confidence level, the average monthly residential water usage in the city. Based on

torisob [31]

Answer: 82

Step-by-step explanation:

The formula to find the sample size is given by :-

$n= (\dfrac{z^*\cdot \sigma}{E})^2$

, where E = Margin of error.

$\sigma$ = Population standard deviation for the prior study.

As per given , we have

$\sigma=387.40$ gallons.

Margin of error : E= 110 gallons

Critical value for 99% confidence level = z* = 2.576

Then, the required sample size : $n= (\dfrac{(2.576)\cdot (387.40)}{110})^2$

$n= (9.07220363636)^2\approx82$ {Rounded to the nearest integer.}

Hence, the minimum sample size = 82
