Stable cost reporting in a manufacturing setting is typically a sign that operations are running smoothly. The accounting department at Rockwell Collins, an avionics manufacturer, analyzes the variance of the weekly costs reported by two of its production departments. A sample of 16 cost reports for each of the two departments shows cost variances of 2.3 and 5.4, respectively. Is this sample sufficient to conclude that the two production departments differ in terms of unit cost variance? Use α = 0.10 (to 2 decimals).

Answer:
(a) 4 in²
Step-by-step explanation:
The volume of a rectangular prism is given by the formula ...
V = Bh
where B is the area of the base, and h is the height of the prism.
We can find the area of the base by solving for B.
B = V/h
B = (12 in³)/(3 in)
B = 4 in² . . . . . . . . . . matches the first choice

If f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (f o g)(x)?
Answer:
(f o g)(x) = 3x^2 + 5
Step-by-step explanation:
(f o g)(x) is a composite function in which g(x) = x^2 + 1 becomes the input to f(x) = 3x + 2.
Write out f(x) = 3x + 2 leaving a blank for each x:
f( ) = 3( ) + 2
Now insert g(x) into the first set of parentheses and x^2 + 1 into the second:
(f o g)(x) = 3(x^2 + 1) + 2, or, after simplification,
(f o g)(x) = 3x^2 + 5

A square picture frame with each side length represented by 3x -
5 has a perimeter of 52 inches. Which equation models this situation?
A. 3x - 5 + 4 = 52
B. 3x - 5 = 52
C. 4(3x + 5) = 52
D. 4(3x - 5) = 52
Answer:
D. 4(3x-5) = 52
Step-by-step explanation:
52 is equal the sum of one side multiplied by 4
So
4(3x-5) = 52
Is the right answer
Help meeee.. I’ll mark you brainlist and Uc you scam then i report lol but helpppp me
Answer:
70 units²
Step-by-step explanation:
Area of the figure = area of rectangle + area of triangle
= L*W + ½*bh
L = 10
W = 5
b = 5
h = 18 - 10 = 8
Substitute:
Area of the figure = 10*5 + ½*5*8
= 50 + 20
= 70 units²

Answer:
1. [tex]2^{3}[/tex]
2. It represents [tex]2*2*2*2*2[/tex] and [tex]2*2*2*2*2*2[/tex]
Step-by-step explanation:
1. it would have to be an exponent so 2*2*2 is 8 and 2^3 is also 8
2. it is an exponent so it would basically be multiplying the number times the number/amount of exponents so 2^5= 32 and 2^6=64
hope this helped :)
