Which statements about the data sets are true? Check all that apply.
The data for the group that plays an instrument are more spread out than the data for the group that did not play an
instrument
The data for the group that plays an instrument are more clustered around the mean than the data for the group that did
not play an instrument.
The mean absolute deviation for students who play an instrument is 1.
The data for the group that does not play an instrument are more spread out than the data for the group that does play
an instrument
The mean absolute deviation for the group of students who do not play an instrument is 2
The data for the group that does not play an instrument are more clustered around the mean than the data for the group
that does play an instrument

I believe its:

B, C, D, E

*disclaimer. I am not 100% sure if this is correct, I am just sure that 2 4 6 is NOT correct*

Step-by-step explanation:  

A is not correct

B is correct

C is correct (the mean is 16. so to find MAD, its 0 plus 2, plus 1 plus 1, which is 4. 4 / 4 = 1

D is correct

E is correct (mean is 4, so 2 plus 2 plus 0 plus 4 is 8, 8 /4 = 2)

F is not correct

(if this is not correct either, i sincerely apologize)

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
