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




His jump was of 272.45 inches
Answer:
function a is linear and its equation is y=(5/3) x
The answer will be 587,328 whenever added!
Answer: 19,11,17 and 13,22,14
Step-by-step explanation:
The two smallest numbers (11, 17) added together must be a bigger number than the biggest number (19)...... 11 + 17 = 28
28> 19 :)
