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.
Answer:
Look at the attached picture
Step-by-step explanation:
It is given that the center of the circle is (-3.2,2.1) and radius is 4.3.
3 13/20 yards.
Make 1 1/4 to 1 5/20
make 2 2/5 to 2 8/20
Add them together and get the answer!
Answer: He will walk 2 1/4 miles in an hour
Step-by-step explanation:
8x - 17° = 5x + 19° ( being corresponding angles)
8x - 5x = 19° + 17°
3x = 36°
x = 12°
