Answer:
0.62% probability that a randomly selected person scores above 125 on the IQ test
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:
What is the probability that a randomly selected person scores above 125 on the IQ test
This is 1 subtracted by the pvalue of Z when X = 125. So
has a pvalue of 0.9938
1 - 0.9938 = 0.0062
0.62% probability that a randomly selected person scores above 125 on the IQ test
16 meters
because they went 8 down, then 8 up (even if it is -8).
8 + 8 = 16
So, they climbed 16 meters.

Yes because the last digit ends as an even number and 6 is also even, implying that it can be divisible by 6.
The answer would be 1,411,596 which of course is even.
Hope this helps.
