Let X
X
represent the full height of a certain species of tree. Assume that
X
X
has a normal probability distribution with a mean of 55.9 ft and a standard deviation of 5.8 ft.

A tree of this type grows in my backyard, and it stands 62.9 feet tall. Find the probability that the height of a randomly selected tree is as tall as mine or shorter.

step-by-step explanation:

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

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
