Answer:
D. 68%
Step-by-step explanation:
38/56 = 0.678
Move the decimal over 2 spots to get 67.8
Round that up to 68
points-
(0,2)
(5,3)
(10,4)
I hope this is good enough:
first term (a) = 4
last term (b) = 9
Arithmetic mean (AM)
= ( a + b) / 2
= ( 4 + 9 ) / 2
= 13/2
= 6.5
Geometric mean (GM)
= √a *b
=√4 * 9
=√36
= 6
hope it helps :)
