Answer:

No

Step-by-step explanation:

Belinda babysits her neighborhood's children in the evening every 14 days. Belinda goes to visit her grandmother in the afternoon every 21 days.

If Belinda has both activities planned for today.

The next time Belinda will have both activities on the same day is determined by the Lowest Common Multiples of 21 and 14.

Express each number as a product of its prime factors

21=3 X 7

14 =2 X 7

L.C.M = 2 X 3 X 7 =42

The next time she will have both activities on the same day is 42 days from today. So both activities occurring 30 days from now is impossible.

A committee must be formed with 5 teachers and 4 students. If there are 6 teachers to choose from, and 15 students, how many dif
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
