Answer:
112.98 square units
Step-by-step explanation:
Let's work backwards:
Circumference = 2πr
(37.68)/2π = r
Area = π
Area = π *
Area = 112.983 square units
Solve the system of equations by the substitution method: 4x-y = 35 7x + 6y = 38

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
