Let X be the heights of adult men in America and Y that of women in America
X is N(69.8, 2.69) and Y is N(64.8,2.53)
a) Man is 6 feet 3 inches = 75 inches
Z score =
b) Prob = 0.5-0.4686 = 0.0314
3.14% are shorter than him
c) Y score = 5 ft 11 inches = 71 inches
Z=
d) Prob (Z>2.45) = 0.5-0.4929=0.0071
Nearly 0.71% people are taller than 5 ft 11 inches.
Answer:
<h2>The area of the parallelogram is 300 square meters. Its height (length) is 30 meters and its width is 10 meters.</h2>Step-by-step explanation:
Assuming that the parallelogram is a rectangle, its perimeter would be defined as
Where is the width and
is the length.
But, , so
Which means the sum of its dimensions is 40 meters.
Easily, its dimenions can be 10 meters and 30 meters.
So, its area would be
Therefore, the area of the parallelogram is 300 square meters. Its height (length) is 30 meters and its width is 10 meters.
