Answer: 5.37
Step-by-step explanation:
Let x = ACT scores.
Given: ACT scores have a mean of 20.8 and 9 percent of the scores are above 28. The scores have a distribution that is approximately normal.
i.e. P(X>28)=0.09 (i)
Now,
(ii)
One -tailed z value for p-value of 0.09 =1.3408 [By z-table]
From (i) and (ii)
Hence, the standard deviation = 5.37

Answer:
Infinite values of n.
Step-by-step explanation:
10 - 8n = 2(5 - 4n)

I think your question is missing key information and the one below is similar to yours. Hope it will find you well:
"Alex has a block of wood that is in the shape of a rectangular prism dimensions 70 cm by 50 cm by 30 cm. He cuts a 10-cm square hole through the center of the prism. What is the volume of the remaining solid?
Here is my answer:
The volume of the rectangular prism: 70∗50∗30=105000
The volume in the center (intersection of “square holes”): 10∗10∗10=1000
=> the volume of the remaining solid = The volume of the rectangular prism - The volume in the center = 105000 - 1000 = 104000
