A person eating at a cafeteria must choose 4 of the 13 vegetables on offer. calculate the number of elements in the sample space
Serggg [28]

A person eating at a cafeteria must choose 4 of the 13 vegetables on offer. calculate the number of elements in the sample space for this experiment.

Answer: The number of elements in the sample space for this experiment can be found using the combination formula because the order does not matter here.

Therefore, the number of elements in the sample space for this experiment is:

13C4=\frac{13!}{(13-4)!4!}

              =\frac{13!}{9! \times 4!}

              =\frac{6227020800}{8709120}

              =715

Therefore, the number of elements in the sample space for this experiment is 715.

Setting StartFraction 7 over 3 EndFraction equal to which ratio would result in a valid proportion?
pochemuha

Answer:

Option C is correct

Step-by-step explanation:

In this question, we are asked to select which of the options have the same value as 7/3

We examine the options one urge other.

Option A

9/49; This is wrong as it cannot be divided further to yield while multiples

Option B

18/42; Dividing through by 6 will yield 3/7 which is not same as 7/3; This makes this option wrong too

Option C

42/18; dividing through by 6 will yield 7/3 which makes this option correct

Option D

49/9; This is a dead end as it cannot be divided further to give whole number multiples
