The weights of 1,000 men in a certain town follow a normal distribution with a mean of 150 pounds and a standard deviation of 15 pounds.
from the data, we can conclude that the number of men weighing more than 165 pounds is about
, and the number of men weighing less than 135 pounds is about

Step-by-step explanation:

Let X be the weights of 1000 men in a certain town.

Given that X is N(150, 15)

P(X>165) = P(Z>1) =0.5-0.3413 = 0.1687

No of men weighing more than 165 pounds in 1000 men = 1000(0.1687)

=168.7 =169 men apprxy.

Similarly

P(X<135) = P(Z<2)=0.5-0.4775 = 0.0225

No of men weighing less than 135 pounds is about =0.0225(1000)

= 22.5

=22

11 feet 6 inches and 8 feet 6 inches

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

do you confirm there was a mistake in the question?
