Let the random variable x denote the natural numbers selected at random from one to one hundred. find the mean of x.

1 answer:

3 0

<span>The answer is 50.5. Since X will consist of a random selection of the numbers from 1 to 100, the mean will be the middle of the set of numbers from 1 to 100 (so between 50 and 51). Imagine the set of whole numbers 1 to 100. To calculate the mean, we have to sum all the numbers, then divide by n=100. That gives 50,500/100= 50.5.</span>

Given a triangle with: a =<br> 150, A = 75°, and C = 30°<br> Using the law of sines gives: c = 0

koban [17]

Answer:

$c = 77.6$

Step-by-step explanation:

You may have entered the measure of a side as the measure of an angle.

$\dfrac{\sin A}{a} = \dfrac{\sin C}{c}$

$\dfrac{\sin 75^\circ}{150} = \dfrac{\sin 30^\circ}{c}$

$c\sin 75^\circ = 150 \sin 30^\circ$

$c = \dfrac{150 \sin 30^\circ}{\sin 75^\circ}$

$c = 77.6$

You are correct. Good job!

Which expression is equivalent to 4^ 5x4^ -7÷4 ^-2?

Andre45 [30]

$\bf ~~~~~~~~~~~~\textit{negative exponents} \\\\ a^{-n} \implies \cfrac{1}{a^n} \qquad \qquad \cfrac{1}{a^n}\implies a^{-n} \qquad \qquad a^n\implies \cfrac{1}{a^{-n}}\\\\[-0.35em] \rule{34em}{0.25pt}\\\\ 4^5\cdot 4^{-7}\div 4^{-2}\implies \cfrac{4^5\cdot 4^{-7}}{4^{-2}}\implies \cfrac{4^{5-7}}{4^{-2}}\implies \cfrac{4^{-2}}{4^{-2}}\implies 4^{-2}\cdot 4^2 \\\\\\ 4^{-2+2}\implies \boxed{4^0}\implies 1$
