There are 25 students in a class at the beginning of the school year and the average number of siblings for each student is three. a new student with eight siblings joins the class in november. does the average number of siblings that each student has increase, decrease or stay the same?

because the sibling of new student is more than the average, so the total average would be increased.

21/58.

hope to be marked brainliest

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
