Since an integer is a whole number, the numbers closer to 0 on the number line are -2 and -1, so there are 2 options.
The answer is 2 choices, in short.
2800-2100=700
2800/700=4

since each block is 3/8 of a mile, then how many miles in 4½? well, it'd just be their product, but let's firstly convert the mixed fraction to improper.

Answer:
The z-score for the trainee is of 2.
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
The mean of the test scores is 72 with a standard deviation of 5.
This means that 
Find the z-score for a trainee, given a score of 82.
This is Z when X = 82. So



The z-score for the trainee is of 2.
