The heights of 200 kindergarten students are normally distributed with a mean of 40 and a standard deviation of 1.8 inches. approximately how many students have a height between 37.3 inches and 44.5 inches?

what’s the answer

Step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

you can't solve x because it is 2 linear equation and you only have one equation
