Lorrie wants to determine the average amount of time that students at her school spend on the computer each day. There are 350 students in 15 classes. The number of boys and girls is approximately equal. Which is the most random sample? 50 students in the art club
40 girls on her soccer team
2 students from each of the 15 classes
10 students from each of the 3 computer electives

2 students from each of the 15 classes because we don’t know the exact amount

C for the lazy readers

Step-by-step explanation:

just finished taking the test

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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
