A set of college student heights are normally distributed with a mean of 170.4 centimeters and a standard deviation of 10 centimeters.

What proportion of student heights are between 170.5 centimeters and 180.3 centimeters?
you may round your answer to four decimal places

.3349

Step-by-step explanation:

According to Khan Academy

for a proportion of student heights between 145 cm and 171 cm it is 0.5184

Step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
