Answer:
Yes, the constant of proportionality is 1.5
Step-by-step explanation:
Using the normal distribution, it is found that a production worker has to make $542.64 a week to be in the top 30% of wage earners.
<h3>Normal Probability Distribution</h3>
In a normal distribution 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
.
- The standard deviation is of
.
- The lower bound of the top 30% is the 70th percentile, which is X when Z has a p-value of 0.7, so <u>X when Z = 0.84.</u>

81a²-25 would be the answer I'm pretty sure. Hopefully I helped.
Answer:
y = 2x - 10
Step-by-step explanation:
The slope is 4 + 4 / 7 - 3 = 8 / 4 = 2
y = 2x + b
-4 = 6 + b
b = -10
