Find 9/20 of 100

9/20 * 100 = 900/20 = 45

So 45 people voted to change the law, and that's not enough.

The picture is unclear so I cannot really help. I'm sure I could if it was clearer though.

Using the normal distribution, it is found that Sue will get a letter grade of B.

In a <em>normal distribution </em>with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.
After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem, Sue got a grade of 0.85, hence $z = 0.85$ .

Looking at the z-table, z = 0.85 has a p-value of 0.8023, hence she is approximately in the top 20%, which is below the top 15% but above the top 50%, hence she got a letter grade of B.
