M(slope) = (Y2(13)-Y1(-5))/(X2(-7)-X1(3)
so your equation is M= (13-(-5))/(-7-3)
Answer:
Step-by-step explanation:
I'm guessing the repeating part is 89 at the end, so that
Then

An arguably quicker way without using geometric series:
Using the normal distribution, the z-score that separates the bottom 70% from the top 30% is z = 0.525.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The z-score that separates the bottom 70% from the top 30% is <u>z with a p-value of 0.7</u>, hence z = 0.525.
