Answer:
Step-by-step explanation:
If you are always included to lead, that leaves 10 students to choose from.
If all that is important is being selected, then there are 10C3 = 120 ways to choose them.

Answer:
Figure 1
Step-by-step explanation:
Congruent shapes are shapes that share the same side lengths and angle measures. In figure 1, we see that all sides and angles are marked equal, thus both shapes are congruent.

Step-by-step explanation:
There were 29 students in band. This includes the 9 in both band and drama; this leaves 20 in only band.
There were 17 students in drama. This includes the 9 in both band and drama; this leaves 8 in only drama.
There were 70 students sampled; this means that
70-(20+8+9) = 70-37 = 33 students in neither band nor drama.
There were 8 in only drama.
Since there were 29/70 in band, this means the director can assume he will have
29/70(350) = 29/70(350/1) = 10150/350 = 145 to show up the first day.
