Answer:
99.1 is the 90th percentile of these scores.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 85
Standard Deviation, σ = 11
We are given that the distribution of score is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.90
Calculation the value from standard normal z table, we have,

Putting values, we get,
Thus, 99.1 is the 90th percentile of these scores.

Answer: 1 pound per $2
Step-by-step explanation:
Imagine this problem as a ratio:
Pounds : Dollars
3 : 6
To simplify this ratio, we see that a common divisor(in fact the only common divisor) is 3.
3/3 : 6/3
1 : 2
Therefore, we get 1 pound per $2
Basically, you try to find 2 numbers that divide to 3/2. So, using trial and error, plug in numbers for x in this expression: x/24=3/2, and solve to find the number that makes it true. You end up getting 36/24=3/2. Hope that helps! :)
