Fractions,rats, and percents all interconnect. For ext,50%=11/2 =1:2
Given:
μ = 70, the mean
σ = 10, the standard deviation
The random variable is x = 65.
Calculate the z-score.
z = (x - μ)/σ = (65 -70)/10 = - 0.5
From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.
Answer: 30th

Answer:
59 meters
Step-by-step explanation:
A=L*W
165=L*22
L=165/22=7.5
7.5=L
P=L+L+W+W
7.5+7.5+22+22=59
