Answer:
8 times 4= 32-7=25
Step-by-step explanation:
f(g(x)) means to plug the value of g(x) into every x you see in f(x) and do the math.
g(x) = 3x
f(3x) = 2(3x) - 1
f(3x) = 6x - 1
So, f(g(x)) = 6x - 1.
Understand?
h(f(x)) means to plug the value of f(x) into every x you see in h(x) and do the math.
h(x) = x^2 + 1
h(2x - 1) = (2x - 1)^2 + 1
h(2x - 1) = (2x - 1)(2x - 1) + 1
h(2x - 1) = 4x^2 - 4x + 1 + 1
h(2x - 1) = 4x^2 - 4x + 2
So, h(f(x)) = 4x^2 - 4x + 2

This is called COMPOSITION OF FUNCTIONS.
Answer:
$561.00
Step-by-step explanation:
Answer:
let s(13,7) be x1,y1
B(-2,-7) be x2,y2
we know
midpoint = [(x1+x2)/2, (y1+y2)/2]
(11/2,0)

<h2>
Answer with explanation:</h2>
As per given , we have
n= 88
Population standard deviation :
Critical value for 98% confidence interval : n
Margin of error :
98% confidence interval :
The 98% confidence interval (34.36, 38.64) found by normal distribution with the appropriate calculations for a standard deviation that is known is narrower than the interval (28.7,44.3) found by the t-distribution (population standard deviation is unknown) .
