Answer:

Step-by-step explanation:
Since the number of residents within five miles of each of your stores is asymmetrically distributed, the distribution of the sample means will be approximately normal with a mean of 25 thousand.
The standard deviation of the sample means is:


The z value is 
We plug in the values to get:

The area to the right of 1.87 is
.
The probability that the average number of residents within five miles of each store in a sample of 50 stores will be more than 27.8 thousand is 3.07%

Answer:
5x + 6y = -14
Step-by-step explanation:
Standard form means the x term will be on the farthest left, then the y term next, set equal to the constant (plain number) all by itself on the right.
Like this:
Ax + By = C
So you have
-5x - 14 = 6y
Add 14 to both sides.
-5x = 6y + 14
Subtract 6y from both sides.
-5x - 6y = 14
Also multiply both sides by -1, to make sure your A value (number next to the x) is positive.
5x + 6y = -14
