PLEASE HELP!!!!! And explain too! Thanks!!!
kenny6666 [7]

I don't know any <em><u>slick</u></em> way to do this.  I would just list the prime numbers
between 40 and 50 and test them one at a time.

The prime numbers between 40 and 50 are: 41, 43, 47

<u>Test 41:</u>
-- add 1 . . . 42
-- prime factors of 42 . . . 2, 3, 7
-- sum of the factors . . . 12

<u>Test 43:</u>
-- add 1 . . . 44
-- prime factors of 44 . . . 2, 11
-- sum of the factors . . . 13

<u>Test 47:</u>
-- add 1 . . . 48
-- prime factors of 48 . . . 2, 3,
-- sum of the factors . . . 5

Maybe I'm not understanding how to list prime factors, but so far,
I haven't found any number that answers the question.

Maybe if I write the prime factorization of 44 like this:

               44 = 2 * 2 * 11

Now the items in the prime factorization do add up to 15.
So the answer would seem to be <em>43.</em>

Select the correct answer.
Liono4ka [1.6K]

Answer:

Option C.

Step-by-step explanation:

It is given that,

Total number of applicants = 9

Number of job = 3

We need to select 3 applicants out of 9. So, the required number of ways is

^9P_3=\dfrac{9!}{(9-3)!}

^9P_3=\dfrac{9\times 8\times 7\times 6!}{6!}

^9P_3=9\times 8\times 7

^9P_3=504

Therefore, there are ^9P_3=504 ways the positions can be filled because the order in which the applicants are chosen matters.

Hence, the correct option is C.
