lawyer [7]

Answer:

$389.35

Step-by-step explanation:

A certain computer costs $599.00 at Best Buy. On Black Friday, it is on sale for 35% off.

So, after 35% off the price of the computer will reduce from $599.00.

We are asked to find the cost of the computer on Black Friday.

Therefore, the price of the computer will reduce by $[599 \times \frac{35}{100}] = 209.65$ Dollars.

And the reduced price on the Black Friday will be $(599 - 209.65) = $389.35 (Answer)

The Office of Student Services at UNC would like to estimate the proportion of UNC's 34,000 students who are foreign students. I

Pachacha [2.7K]

Answer:

Mean is 3.05

Standard deviation is 1.69.

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they are foreign, or they are not. This means that we can solve this problem using concepts of the binomial probability distribution.

Binomial probability distribution

The probability of x sucesses on n repeated trials, with p probability.

In this problem, we have a sample of 50 students, so $n = 50$ . The proportion of all UNC students that are foreign students is 0.061, so $p = 0.061$ .
