Answer:
Step-by-step explanation:
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:
Perimeter of a rectangle = 2(L + W)
Step-by-step explanation:
L = length
W = width
In a rectangle, of the four sides, there are two equal length and 2 equal width
Length = 2 sides
Width = 2 sides
perimeter of a rectangle is the sum of the lenths of its four sides.
Perimeter of a rectangle = L + L + W + W
= 2L + 2W
Factorize
= 2(L + W)
Perimeter of a rectangle = 2(L + W)
This expression shows the relationship
The formula is
A=p (1+r)^t
A future value?
P present value 7
R interest rate 0.05
T time 9 years
A=7×(1+0.05)^(9)
A=10.86
B. (4,2)
G is 1 right and 1 up and point B is 1 right and 1 down
