X cannot be 6 or -2/5 because if they were the denominator would be zero
Answer: B
Step-by-step explanation: to find the mean you add all of the values and divide it by the number of values you added. so it would be (13+14+14+14+14+14+15+15+15+15+15+15+16+16+17)/15 which equals 14.8
I believe 3 is the correct answer
The answer is B, g(x)= (9x)^2
Solve this ratio:
5 40
--- = -----
8 x
Then 5x = 320, and x = 64. So, on a day on which there are 40 lunch customers, there are 64 dinner customers (answer).
