Note that Cheryl wants to find the number of hours <u>seventh grade boys and girls</u> spend on homework each week.

There are multiple causes of a biased sample.  Two of the most obvious ones I find are:

1.  She's surveying <u>girls</u>, but she is trying to get data on the number of hours <em>all</em> seventh graders (boys <em>and</em> girls) spend.

2. She's surveying 50 girls from the <u>entire school</u>, although she is trying to get data on seventh graders only.

Can someone pls help me with this question pls NUMBER 6
katrin2010 [14]

Supplementary angles definition: They add up to 180°

There are several ways to prove a parallelogram:

1. Opposite sides theorem converse

2. Opposite angles theorem converse

3. Parallelogram diagonals theorem converse

4. Parallel congruent sides theorem

∠P + ∠Q = 180° --1

∠P + ∠S = 180° --2

1: ∠P = 180° - ∠Q

Sub 1 into 2:

180° - ∠Q + ∠S = 180°

180° + ∠S = 180° + ∠Q

∠S = ∠Q

Or you can try saying the opposite sides are parallel, since they are interior angles and those are straight lines
