Anestetic [448]3 years ago
4 0

Answer:

1

Step-by-step explanation:

Using the definition

nC_{r} = \frac{n!}{r!(n-r)!}

where n! = n(n - 1)(n - 2) × 3 × 2 × 1

and 0! = 1

3C_{3}

= \frac{3!}{3!(3 - 3)!}

= \frac{3!}{3!(0!)}

= \frac{3!}{3!} = 1

Caroles new job will pay $3,525 per month, but about 30% will be withheld for taxes. Estimate her pay after taxes
Juli2301 [7.4K]

Answer:

i think the answer would be $2467.5 per month (got exact answer without estimating)

Step-by-step explanation:

30% (taxes) in decimals would be 0.3

so .3 mutiplyed by 3,525 would equals 1057.5

which then you would subtract 3,525-1057.5 =

$2467.5

There are 5 questions on a multiple choice exam, each with five possible answers. If a student guesses on all five questions, wh
Mrac [35]

Answer:

20.5\%

Step-by-step explanation:

Let's write out a case for two specific questions being correct and the rest being incorrect:

\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot \frac{4}{5},

The \frac{1}{5} represents the chances of getting the question correct, as there are 5 answers and 1 correct answer choice.

The \frac{4}{5} represents the chances of getting the question incorrect, as there are 5 answers and 4 incorrect answer choices.

The equation above does show the student getting two answers correct and three answers incorrect, but it only shows one possible case of doing so.

We can choose any two of the five questions to be the ones the student gets correct. Therefore, we need to multiply this equation by the number ways we can choose 2 from 5 (order doesn't matter): \binom{5}{2}=10.

Therefore, the probability the student gets two questions correct is:

\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot \binom{5}{2}=\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot 10=0.2048\approx \boxed{20.5\%}
