Step-by-step explanation:
To solve this, you either need x or y. So x or y can be the missing values. The most you can do is simply move one of the terms to the other side.

Answer:
<em> 85% level of the confidence interval is</em>
<em>(26.337, 26.662)</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given the size of the sample 'n' = 295
Mean of the sample x⁻ = 26.5
The Standard deviation of the Population = 2.7
85% level of the confidence interval is determined by

Critical value Z₀.₁₅ = 1.036
<em> 85% level of the confidence interval is determined by</em>


( 26.5 - 0.1628 , 26.5+0.1628)
(26.3372,26.6628)
Answer:

Step-by-step explanation:
The inverse of a function is when the x and y are swapped. So the first step is to write f(x) as y and then swap the x and y
Original Equation:

write f(x) as y (since that's what it represents)

Swap x and y

Square both sides

Add 1 to both sides

So this gives you the equation:
