All in all you would get the answer x+y=1.
Standard deviation=4.
let the mean be 12 and the score be 0 (therefore 12 point difference.)
0-12/s=-3 (s being standard deviation)
-12/4 = -3
If n is the first integer, then n+2 is the second one. The equation for the sum can be written as
n + (n+2) = 24 . . . . . . this equation can be used to solve the problem
2n = 22 . . . . . . . . . . . simplify, subtract 2
n = 11
The integers are 11 and 13.

I like to solve problems like this by looking at the average of the integers. Here, it is 24/2 = 12. The consecutive odd integers whose average is 12 are 11 and 13.
Answer:
8hours
Step-by-step explanation:
10000÷5=2000
so the restaurant earns 2000$ per hour
8×2000=16000
