. A random sample of 250 working adults found that 37% access the internet at work, 44% access the internet at home, and 21% acc

Answer:

0.6 is the required probability.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 250

Probability of accessing internet at work = 37%

$P(W)=0.37$

Probability of accessing internet at home = 44%

$P(H)=0.44$

Probability of accessing internet at work and home = 21%

$P(W\cap H)=0.21$

We have to evaluate the probability that a person in this sample accesses the internet at home or at work.

$P(H\cup W) = P(H) + P(W) - P(W\cap H)\\P(W\cup H) = 0.37 + 0.44-0.21\\P(H\cup W) = 0.6$

Thus, 0.6 is the probability that a person in this sample accesses the internet at home or at work

If we wanted to know how high a 5th-grade student could jump, how many students would be reasonable to test? 5, 12, 30, or 200.

The right amount to test would be 30.

200 is to many kids and 12 is not enough.

Hope this Helps!!

Find the absolute maximum and minimum values of the following function on the given interval. If there are multiple points in a

Bond [772]

$f(x)=3\sin x+3\cos x\implies f'(x)=3\cos x-3\sin x$

$f$ has critical points where $f'=0$ :

$3\cos x-3\sin x=0\implies\cos x=\sin x\implies\tan x=1\implies x=\pm\dfrac\pi4+2n\pi$

where $n$ is any integer. We get solutions in the interval $\left[0,\frac\pi3\right]$ for $n=0$ , for which $x=\frac\pi4$ .

At this critical point, we have $f\left(\frac\pi4\right)=3\sqrt2\approx4.243$ .

At the endpoints of the given interval, we have $f(0)=3$ and $f\left(\frac\pi3\right)=\frac{3+3\sqrt3}2\approx4.098$ .

So we have the extreme values

$\max\limits_{x\in\left[0,\frac\pi3\right]}f=3\sqrt2$

$\min\limits_{x\in\left[0,\frac\pi3\right]}f=3$
