Answer:
i use the two sided t-test.
Step-by-step explanation:
it would be nearly impossible to ascertain with certain the proposition above but we would rather guess using the parameters that were available at the time.
generally in statistics, we use a two sided t-test when an area of a distribution is two-sided and tests whether a particular given sample in question is greater than or less than a exact range of values.
the two sided t-test is mostly used in null-hypothesis testing and testing for statistical significance.

Answer:
It's choice B.
Step-by-step explanation:
Let's look the one you have chosen (A):
f(x) = x - 2/ 7 + 8
x-2 / 7 = f(x) - 8
x- 2 = 7(f(x) - 8)
x = 7(f(x) - 8) + 2
The inverse)= 7(x - 8) + 2
So it's not A.
B. f(x) = 5(x/4) - 3
5x / 4 = f(x) + 3
5x = 4(f(x) + 3)
x = 4(f(x) + 3 / 5
So the inverse is 4(x + 3) / 5
So it is B.
<span>3(7 + 4)2 − 14 ÷ 7
First do the parenthesis
7 + 4 = 11
so the question looks like: 3(11)2 - 14/7
Then multiply 3, 11, and 2 together
3 x 11 x 2 = 66
66 - 14/7
14/7 equals to 2
66 - 2
Then just simplify
66 - 2 = 64
64 is your answer
