The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1700 hours and a standard deviation of 45 hours. Using the empirical rule,

what percentage of light bulbs last between 1655 hours and 1745 hours?

is should be y = 5x

step-by-step explanation:

correct me if im wrong

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

-11/5> -11/3
