6) Girls at CRHS have an average height of 65.5 inches with standard deviation of 2.3 inches. Boys have an average height of 71 inches with standard deviation of 3.5 inches. If girls and boys were picked
at random and the difference in height calculated, what would the average height difference
be? What would the standard deviation of the differences in height be?

the correct is answer is a 9-sided polygon!

use formula for the circle a=3.14

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

hope that .

do you confirm there was a mistake in the question?
