Suppose the walking step lengths of adult males are normally distributed with a mean of 2.4 feet and a standard deviation
of 0.8 feet.
The mean is
The standard deviation is

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

1) letter c.

2) 4 square root of 9

hope this
