1. It is estimated that the weight of a population of brown bears is approximately
normally distributed with a mean of 600 pounds and a standard deviation of 120
pounds. Approximately what proportion of the bears in the population weigh less
than 720 pounds?

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
