Answer:

74.5%

Step-by-step explanation:

The total number of people sampled is 1000 people.

There are 745 people who where corrective lenses.

Percent is (part)/(whole); in this case, the part is 745 and the whole is 1000, so:

745/1000 = 74.5%

Thus, the answer is 74.5%.

Hope this helps!

In a club there is 13 women and 8 men. A committee of 9 women and 4 men is to be chosen. How many different ways are there to se

sammy [17]

Answer:

The total number of ways to select 9 women and 4 men for the committee is 50,050.

Step-by-step explanation:

The club has 13 female members and 8 male members.

The committee to be formed must have 9 female members and 4 male members.

The possible number of ways to select 9 female from 13 females is:

$n(F)={13\choose 9}=\frac{13!}{9!(13-9)!}=715$

The possible number of ways to select 4 male from 8 males is:

$n(M)={8\choose 4}=\frac{8!}{4!(8-4)!}=70$

Compute the possible total number of ways to select 9 women and 4 men for the committee as follows:

Total number of ways to select 9 women and 4 men = n (F) × n (M)

$=715\times70\\=50050$

Thus, the total number of ways to select 9 women and 4 men for the committee is 50,050.
