What are the factors of (r+t)(e)

mina [271]

Depending on the values of 'r', 't', and 'e', the numerical value of that expression
might have many factors.

For example, if it happens that r=5, t=1, and e=4 for an instant, then, just
for a moment, (r + t)(e) = (5+1)(4) = 24, and the factors of (r+t)(e) are
1, 2, 3, 4, 6, 8, 12, and 24 . But that's only a temporary situation.

The only factors of (r+t)(e) that don't depend on the values of 'r', 't', or 'e' ,
and are always good, are (<em>r + t</em>) and (<em>e</em>) .

Find the missing side of the triangle. Side LaTeX: cc is the hypotenuse and sides LaTeX: aa and LaTeX: bb are legs. Leave your a

mylen [45]

Answer:

$c = 2\sqrt{5$

Step-by-step explanation:

Given

$a = 2$

$b = 4$

c = hypotenuse

Required

Find c

Using Pythagoras theorem, we have:

$c^2 = a^2 + b^2$

Substitute values for a and b

$c^2 = 2^2 + 4^2$

$c^2 = 4 + 16$

$c^2 = 20$

Take square roots of both sides:

$c = \sqrt{20$

Express 20 as 4 * 5

$c = \sqrt{4 * 5$

Split surd

$c = \sqrt{4} * \sqrt{5$

Take square root of 4

$c = 2 * \sqrt{5$

$c = 2\sqrt{5$

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 $p = 0.061$ .

The mean is given by the following formula:

$E(X) = np = 50*0.061 = 3.05$

The standard deviation is given by the following formula:

$\sigma = \sqrt{n*p*(1-p)} = \sqrt{50*0.061*(1-0.061))} = 1.69$
