Suppose the number of residents within five miles of each of your stores is asymmetrically distributed with a mean of 20 thousand and a standard deviation of 11.7 thousand. What is the probability that the average number of residents within five miles of each store in ta sample of 45 stores will be more than 22.6 thousand? can someone help me solve?

the answer is the third / last answer

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

nope.   happens to me as well.
