Answer:
1. option D
2. option A
Step-by-step explanation:
Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations. Thus, this sampling is independent. The sampling is independent because an individual selected for one sample does not dictate/affect which individual is to be in the second sample.
The variable is qualitative because it is an attribute classification. A qualitative variable are variables that are not numerical. It describes data that fits into categories (personality type).
In the fourth step, he didn’t put the “negative” sign for 4.

Answer:
A1.) 87 + 63 =150
180 - 150 = 30
all the As is the same formula....
B1.) 180 - 123 = 57
57 + 82 = 139
180 - 131 = 41
F(x)^-1 is asking for the inverse function of f(x).
The first step to finding the inverse is:
1) change f(x) to y
2) switch x and y
3) resolve the equation for y =
f(x) = 4x - 3
y = 4x - 3
x = 4y - 3
add 3 to both sides
x + 3 = 4y
divide both sides by 4
(x + 3)/4 = y
y = (x + 3)/4
