Mean = (14 + 16 + 7 + 9 + 11 + 13 + 8 + 10) ÷ 8 = 11
Variance =
[ (14-11)²+(16-11)²+(7-11)²+(9-11)²+(11-11)²+(13-11)²+(8-11)²+(10-11)² ]/7 = 9.71
Answer: 9.71
Answer:
-3fg
Step-by-step explanation:
I can't tell exactly what you're trying to say but if you're trying to say:
g x (f x (-3)), then here's how you do it:
g x (f x (-3))
Multiplying a positive and a negative equals a negative: (+) x (-) = (-), then use the commutative property to reorder the terms.
g x (-f x 3)
g x (-3f)
Multiplying a positive and a negative equals a negative: (+) x (-) = (-), the use the commutative property to reorder the terms.
-g x 3f
-3fg
I think its B even though they are not in the same order and form they are still the same just in different ranges
