Answer:
45 degrees
Step-by-step explanation:
Using the normal distribution, it is found that 0.0329 = 3.29% of the population are considered to be potential leaders.
In a <em>normal distribution</em> with mean
and standard deviation
, the z-score of a measure X is given by:
- 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 is of 550, hence
.
- The standard deviation is of 125, hence
.
The proportion of the population considered to be potential leaders is <u>1 subtracted by the p-value of Z when X = 780</u>, hence:



has a p-value of 0.9671.
1 - 0.9671 = 0.0329
0.0329 = 3.29% of the population are considered to be potential leaders.

Answer:
1. (-3,2) and (-1,2)
Step-by-step explanation:
Reflection over x axis results in change y-coordinates to opposite sign and x-coordinates remain as is
<u>So the coordinates become:</u>
- A(-3, -2) → A'(-3, 2)
- B(-1, -2) → B'(-1, 2)
Correct option is the first one
If it’s giving you a chart you’ll have to use the inputs which are the x and then simplify each number and it will give you the answer of your outout
