Answer:
A = 16
B = 14
C = 34
Step-by-step explanation:
If we start with trying to find A, then we would add these numbers together:
2+ 14 = 16
Now that we have the total for part A, we can add the bottom row:
16+18 = 34
Another way to find C is to first solve for the value of B which can be worked out as follows:
2+12 = 14
Then we would add all the totals on the right to get the grand total of men and women in the sample:
14+20 = 34
Hope this Helps!
12
note that (f + g)(x) = f(x) + g(x)
f(x) + g(x) = x + 2 + x² - 2 = x² + x
To evaluate (f + g)(- 4) substitute x = - 4 into f(x) + g(x)
(f + g)(- 4) = (- 4)² + (- 4) = 16 - 4 = 12
Answer: b) 160 c) 1500
Step-by-step explanation: b) 50 + 50 + 30 + 30 = 160 c) 50 x 30 = 1500
