Answer:
The score that separates the lower 5% of the class from the rest of the class is 55.6.
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 question:

Find the score that separates the lower 5% of the class from the rest of the class.
This score is the 5th percentile, which is X when Z has a pvalue of 0.05. So it is X when Z = -1.645.


The score that separates the lower 5% of the class from the rest of the class is 55.6.
Step-by-step explanation:
Beef = 12 * 8 (cause 25 * 8 = 200)
Beef = 96
Chicken = 8 * 8 (cause 25 * 8 = 200)
Chicken = 64
Pasta = 5 * 8 (cause 25 * 8 = 200)
Pasta = 40
Answer- C] There are 32 more students who want beef meal more than want a chicken meal
The original price would be 260 I think. Because if they paid 25% that should be 1/4 so add 65 three more times.
The angle with the largest measure is opposite the longest side. The longest side is 12. It is opposite angle B. The appropriate choice is ...
B. ∠B
