One year, many college-bound high school seniors in the U.S. took the Scholastic Aptitude Test (SAT). For the verbal portion of

Using the normal distribution, it is found that 62.46% of students would be expected to score between 350 and 550.

<h3>Normal Probability Distribution</h3>

In a normal distribution 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, the mean and the standard deviation are respectively, given by: $\mu = 425, \sigma = 110$

The proportion of students that would be expected to score between 350 and 550 is the <u>p-value of Z when X = 550 subtracted by the p-value of Z when X = 350</u>, hence:

X = 550:

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

$Z = \frac{550 - 425}{110}$

$Z = 1.14$

$Z = 1.14$ has a p-value of 0.8729.

X = 350:

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

$Z = \frac{350 - 425}{110}$

$Z = -0.68$

$Z = -0.68$ has a p-value of 0.2483.

0.8729 - 0.2483 = 0.6246

62.46% of students would be expected to score between 350 and 550.

The grocery store is located at a point on a coordinate plane with the same y coordinate as the bank but with the opposite x coo

Cerrena [4.2K]

The vertical axis on a graph is the y-axis and the horizontal axis is the x-axis. Keeping this in mind, if they have the same y coordinate that means vertically they are on the same level but their x coordinates are opposite each other, this means 2 things:
1. they are not on the same level horizontally
2. you have to cross the vertical (y) axis to get from one point to the other.

So to answer your question, These two points are reflected across the y axis.

Hope this helps.
