F(-2) is the f(x) when x is -2. From the table, it is 1.
Answer:
He missed 14 questions
Step-by-step explanation:
Total = Right + Miss ⇒ t = r + m
Right = Miss + 12 ⇒ r = m + 12
t = 40
Since t = r + m and r = m + 12 then:
t = m + 12 + m
t = 2m + 12
40 = 2m + 12
28 = 2m
m = 14
90= 3x + 2x
90= 5x
x= 18
one measure = 3(18)= 54
the other one= 2(18)= 36
hope this helps!
Multiply 8.5 by 12, multiply 7.5 by 20, add them together to get 252, then divide that by 32 to get 7.875. 7.875 is the mean of all 32 measurements
Answer:
Aren't you just suppose to multiple the 24 and 20 to get 480
