Find the mean of the following data: 9, 15, 17, 18, 6, 20, 8, 5, 18, 18, 10, 5, 14, 12, 10,7 a. 15 b. 12 c. 11 d. 18

The answer is 12 (so the letter B)

Step-by-step explanation:

9+15+17+18+6+20+8+5+18+18+10+5+ 14+12+10+7=192

Then if you count the amount of numbers you find that there is 16 numbers.

You then do 192 ÷16 which gives you 12

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
