Answer:
His jump was of 272.45 inches
Step-by-step explanation:
Problems of normally distributed samples are 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:
75th percentile
X when Z has a pvalue of 0.75. So X when Z = 0.675

Answer: The required number of ways is 25401600.
Step-by-step explanation: Given that seven men and seven women line up at a checkout counter in a store.
We are to find the number of ways in which they can line up, if the first person in line is a man , and the people in line alternate man, woman, man, woman and so on.
Since the first person is a man, so
for first position, we have 7 options.
There are alternate man and women in the line, so the second person must be a women.
That is, we have 7 options for the second position.
Similarly, for 3rd and 4th positions, we have 6 options for each, and so on.
Therefore, the number of ways in which the 14 persons can line up is
Thus, the required number of ways is 25401600.
