Answer:
69.15% probability that a randomly selected customer spends less than $105 at this store
Step-by-step explanation:
Problems of normally distributed samples are 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:

What is the probability that a randomly selected customer spends less than $105 at this store?
This is the pvalue of Z when X = 105. So



has a pvalue of 0.6915
69.15% probability that a randomly selected customer spends less than $105 at this store

Step-by-step explanation:
Use the co‐interior rule, corresponding angle rule, alternate angle rule and vertical opposite angle rule to solve the question above.
angle G5 = angle K1 reason : corresponding angles
angle J1 = angle H3 reason: vertical opposite angles
angle J2 = angle K4 reason: vertical opposite angles
angle G5 = angle K4 reason: co‐ interior angles
angle F6 = angle K4 reason: alternate angle
Answer:
You need to find k, the constant of proportionality, by dividing y with its corresponding x.
You take (8x - 6) then add 80 =90 then solve for x
8x-6+80 =90
x= 2
