I think b
Step-by-step explanation:
because 2x + 2x = 4x and 5 + 3 = 8
Answer:
Step-by-step explanation:
Given that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in. and a standard deviation of sigma equals 1.2 in.
We have to find values of x such that
and

a=2.33 and b =-2.33 as z values
Let us convert to X values

i.e. values below 19.304 and above 25.496
Hence for x below 19.304 and above 25.496 are significantly low and high.
24.2 length is not significantly high.
Answer:
D. a^2 - 6a - 16
Step-by-step explanation:
The product is found using the distributive property.
(a -8)(a +2) = a(a +2) -8(a +2)
= a^2 +2a -8a -16
= a^2 -6a -16 . . . . . matches choice D
