Answer:
negative reciprocals of each other
Answer:
The limit that 97.5% of the data points will be above is $912.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

Find the limit that 97.5% of the data points will be above.
This is the value of X when Z has a pvalue of 1-0.975 = 0.025. So it is X when Z = -1.96.
So




The limit that 97.5% of the data points will be above is $912.
Because Point Slope Form contains m, or slope, in itself, look at the number that is multiplying the parentheses.
-5/4 is m, or slope.
So all you need to do is subtract m from both sides.
Then you have your answer
m = 1

A y = x + 1
Step-by-step explanation:
The line starts at 1 on the y-axis so the u intercept will be 1
