Answer:

A 16°

B -8°

C 6°

D -16°

E -4°

Step-by-step explanation:

Look at 0° and 10°. There are 5 lines from one to the other, so each line represents 2°.

3 lines above 10° = 10° + 3 * 2° = 10° + 6° = 16°

1 lines above -10° = -10° + 2° = -8°

3 lines above 0° = 0° + 3 * 2° = 0° + 6° = 6°

2 lines above -20° = -20° + 2 * 2° = -20° + 4° = -16°

3 lines above -10° = -10° + 3 * 2° = -10° + 6° = -4°

Answer:

b. 56

Step-by-step explanation:

Please consider the complete question.

There are 8 members on a board of directors. If they must form a subcommittee of 3 members, how many different subcommittees are possible?

We will use combinations for solve our given problem.

$^nC_r=\frac{n!}{r!(n-r)!}$ , where,

n = Number of total items,

r = Items being chosen at a time.

For our given scenario $n=8$ and $r=3$ .

$^8C_3=\frac{8!}{3!(8-3)!}$

$^8C_3=\frac{8!}{3!\cdot 5!}$

$^8C_3=\frac{8\cdot7\cdot6\cdot5!}{3\cdot2\cdot1\cdot 5!}$

$^8C_3=8\cdot7$

$^8C_3=56$

Therefore, 56 different subcommittees are possible and option 'b' is the correct choice.
