Ainat [17]

Answer:

8 percent

Step-by-step explanation:

You have to put the biggest number first, then subtract  65.00​ and 60.00. You would get 5, then divide 5 and the original number (60.00). You would get 0.0833333333. Move the decimal two spots to the right. You would get 8 percent.    Hope this helps!

There are 15 technicians and 11 chemists working in a research lab. They need to form a 5 person safety committee. In how many w
Burka [1]
<h2>There are a total 65,780 ways in which the committee can be made of 5 members.</h2>

Step-by-step explanation:

Here, the total number of technicians in the lab = 15

The total number of chemists in the lab  = 11

So, the total members in the lab  = 15 + 11 = 26

So, there are total 26 eligible candidates in the lab from which committee of 5 people has to be made.

Now, since there is <u>no restrictions</u> on the choice, so the committee can be formed in nay way, such that:

It may or may not have any technician.

It may or may not have may chemists.

So, the number of ways 5 member can randomly be chosen from a committee of 26 people  = ^{26} C_5

^{26} C_5 = ^{26} C_5 = \frac{26!}{5! \times 21!}  = 65,780

Hence, there are a total 65,780 ways in which the committee can be made of 5 members.

You know the answer is the third choice (C) because 7^2 is 49 and 8^2 is 56, the two closest squared numbers to 54.

49 < 54 < 56

The square root of 54 is  roughly 7.4

I hope that helps :)
