It’s 0 because it’s a horizontal line and doesn’t have any change.
Answer:
108 feet²
Step-by-step explanation:
Well we can just multiply the corresponding sides of Quadrilateral ABCD to fit Quadrilateral EFGH.
Line EF is 42 feet
Line FG is 18 feet
Line GH is 18 feet
Line HE is 30 feet
The perimeter of Quadrilateral EFGH is
30+18+18+42=
30+36+42=
66+42=
108 feet²

Answer:
7.64% probability that they spend less than $160 on back-to-college electronics
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:

Probability that they spend less than $160 on back-to-college electronics
This is the pvalue of Z when X = 160. So



has a pvalue of 0.0763
7.64% probability that they spend less than $160 on back-to-college electronics
11,000 or 10,000 or 11,200 or 11,230
