You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.

Given f(x) = x+2 and g(x) = x-4 solve for (fg)(x)

kirza4 [7]

Answer: f(g(x)) = x - 2

<u>Step-by-step explanation:</u>

f(x) = x + 2

g(x) = x - 4

f(g(x)) = f(x - 4) = (x - 4) + 2 <em>replaced x with x - 4</em>

= x - 2 <em>simplified</em>

Answer:

D

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here { a, b ] = [ - 1, 2 ], thus

f(b) = 4 ← from (2, 4 )

f(a) = $\frac{1}{2}$ ← from (- 1, $\frac{1}{2}$ ) , thus

average rate of change = $\frac{4-\frac{1}{2} }{2-(-1)}$ = $\frac{\frac{7}{2} }{3}$ = $\frac{7}{6}$ → D
