Answer:
We conclude that the actual average cost per workbook is higher than $27.50.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $27.50
Sample mean, = $28.90
Sample size, n = 44
Alpha, α = 0.05
Population standard deviation, σ = $5.00
First, we design the null and the alternate hypothesis
We use one-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis.
Thus, we conclude that the actual average cost per workbook is higher than $27.50.

Step-by-step explanation:
The wording is all you need, you don't even need to do the math.
Yes they’re congruent as they have exactly the same angles and sides
The rule of reflection over x-axis ⇒⇒⇒ (x,y)→(x,-y)
The rule of reflection over y-axis ⇒⇒⇒ (x,y)→(-x,y)
The rule of reflection over y = x ⇒⇒⇒ (x,y)→(y,x)
=================================================
let the coordinate of any point of the <span>hexagon is (m,n)
</span>
<span>The correct sequence will make the same coordinates
</span>
<span>which mean start with (m,n) and the finish is also (m,n)
</span>
<span>=================================================

Check option a- x-axis, y=x, x-axis, y=x
(m,n) → (m,-n) → (-n,m) → (-n,-m) → (-m,-n)
Wrong set of reflections
====================================================
Check option b- y-axis, x-axis, y-axis
(m,n) → (-m,n) → (-m,-n) → (m,-n)
Wrong set of reflections
=======================================================
Check option c- x-axis, y-axis, y-axis
(m,n) → (m,-n) → (-m,-n) → (m,-n)
Wrong set of reflections
=======================================================
Check option d- y=x, x-axis, y=x, y-axis
(m,n) → (n,m) → (n,-m) → (-m,n) → (m,n)
The correct set of reflections
=======================================================
So, the correct option is <span>⇒⇒ d- y=x, x-axis, y=x, y-axis
</span>
