Answer:
a)
b)
c) Mary's score was 241.25.
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:
a) Find the z-score of John who scored 190
b) Find the z-score of Bill who scored 270
c) If Mary had a score of 1.25, what was Mary’s score?
Mary's score was 241.25.

Answer:
D
Step-by-step explanation:
Answer:
area of the base (length times width) times the length of the prism (corner of the base matching to the top corner of the top base)
Step-by-step explanation:
I hope I explained it good: Length times width of one of the bases; then save that number and multiply it to the remaining length of the prism which usually is on the side (if the prism is upright on one of its bases in problem).
