Answer:
84.13% of homes will have a monthly utility bill of more than $135
Step-by-step explanation:
When the distribution is normal, we use 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 question, we have that:
What percentage of homes will have a monthly utility bill of more than $135?
We have to find 1 subtracted by the pvalue of Z when X = 135.
has a pvalue of 0.1587
1 - 0.1587 = 0.8413
84.13% of homes will have a monthly utility bill of more than $135
Answer:
x = 22
Step-by-step explanation:
(x + 3)/25 = 1
Multiply both sides by 25
x + 3 = 25
-3 -3
x = 22
