The lifespan of a machine is normally distributed with a mean of 18.2 years and a standard deviation of 1.7 years. The manufacturer will replace a machine if it breaks before the guarantee period is over. If the manufacturer is willing to replace no more than 5% of the machines, find the length of time the manufacturer should set for the guarantee PLSS I NEED AN ANSWER FAST !!

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
