Many Rochester Public School students apply and are admitted to a university. Of those students 7 were offered athletics scholarships. A school’s guidance counselors looked at their composite ACT scores (shown in the table), wondering if the university might admit people with lower scores if they were also athletes. Assuming that this group of students were selected randomly, what do you think? Create and interpret a 90% confidence interval. (table attached)

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

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
