Answer:
(5.5,8.5)
Step-by-step explanation:
(8+3)÷2=5.5
(15+2)÷2=8.5
Yes because I just took the test
Answer:
A)
Step-by-step explanation:
Order the set first
27, 28, 35, 37, 43, 47
Median now is: 36 (which is the mean between 35 and 37, the two central numbers )
If you add A) 35,50 then you will still have to compute the mean between 35 and 37 in order to find the median, because you have:
27,28,35,35,37,43,47,50
f(x) =5-3x
g(x)=x²-1
f(g(x)) = f(x²-1)
replacing x by x²-1 in the function f(x) , we get
f(x²-1) = 5-3(x²-1) = 5-3x²+3 =8-3x²
f(g(x)) =8-3x²
now finding g(f(x))
g(5-3x)
replacing x by 5-3x in the function g(x)
g(5-3x) = (5-3x)²-1
g(5-3x) = 5²-30x +9x²-1 = 9x²-30x +24
g(f(x))= 9x²-30x +24
f(g(x)) =8-3x²
in option third the f(g(x)) is -3x³+8 which is incorrect
