(c) 38.5%

(d) 27.1%

(e) 64

(f) 47

(g) The Lions

Step-by-step explanation:

(a) Free throw % for Lions is

\dfrac{10}{18}\times 100\% = 55.6\%

(b) Free throw % for Eagles is

\dfrac{9}{20}\times100\% = 45\%

(c) For the Lions, they attempted a total of 51 + 14 = 65 field goals and made 21 + 4 = 25.

Field goal % for Lions is

\dfrac{25}{65}\times100\% = 38.5\%

(d) For the Eagles, they attempted a total of 45 + 14 = 59 field goals and made 10 + 6 = 16.

Field goal % for Eagles is

\dfrac{16}{59}\times100\% = 27.1\%

(e) Total points by Lions = (10 × 1) + (21 × 2) + (4 × 3) = 10 + 42 + 12 = 64

(f) Total points by Eagles = (9 × 1) + (10 × 2) + (6 × 3) = 9 + 20 + 18 = 47

(g) The Lions won because they had more points.

ZanzabumX [31]

Answer:

8190 ways

Step-by-step explanation:

Given

Teachers = 6

Students = 15

Selection

Students = 4

Teachers = 5

Required

Number of ways of selection

4 students can be selected from 15 students in:

Students= ^{15}C_4

Similarly.

5 teachers can be selected from 6 teachers in:

Teachers= ^{6}C_5

So, the required number of selection is:

Selection = ^{15}C_4 * ^6C_5

Apply combination formula:

Selection = \frac{15!}{(15-4)!4!} * \frac{6!}{(6-5)!5!}

Selection = \frac{15!}{11!4!} * \frac{6!}{1!5!}

Selection = \frac{15*14*13*12*11!}{11!*4*3*2*1} * \frac{6*5!}{1*5!}

Selection = \frac{15*14*13*12}{4*3*2*1} * \frac{6}{1}

Selection = \frac{32760}{24} * 6

Selection = 1365 * 6

Selection = 8190
