Answer:
350 ml
Step-by-step explanation:
70% of 500 ml = 0.7*500 ml = 350 ml
Cross multiply or just multiply both sides by 24
24x/6=36
4x=36
divide both sides by 4
x=9
Answer:
Step-by-step explanation:
Given that X - the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7 inches.
Height of male pilot = 74.2 inches
We have to find the percentile
X = 74.2
Corresponding Z score = 74.2-72.6 = 1.6
P(X<174.2) = P(Z<1.6) = 0.5-0.4452=0.0548=5.48%
i.e. only 5% are below him in height.
Thus the malepilot is in 5th percentile.
