Pls, can you help me? thx.<br><img src="https://tex.z-dn.net/?f=%20%5Ccos%28x%20%2B%20%5Cfrac%7B%5Cpi%7D%7B3%7D%29%20%5Cgeqslant

For $x$ between $-\pi$ and $\pi$ , we have

$\cos x=\frac{\sqrt2}2=\frac1{\sqrt2}$ when $x=\pm\frac\pi4$ ;
$\cos x=1$ for $x=0$ ; and
$\cos x=0$ for $x=\pm\frac\pi2$

$\cos x$ is continuous over its domain, so the intermediate value theorem tells us that

$\cos x\ge\frac{\sqrt2}2$

is true for $-\frac\pi4\le x\le\frac\pi4$ .

For all $x$ , we take into account that $\cos x$ is $2\pi$ -periodic, so the above inequality can be expanded to

$-\dfrac\pi4\le x+2n\pi\le\dfrac\pi4$

where $n$ is any integer. Equivalently,

$-\dfrac\pi4-2n\pi\le x\le\dfrac\pi4-2n\pi$

To get the corresponding solution set for

$\cos\left(x+\dfrac\pi3\right)\ge\dfrac{\sqrt2}2$

simply replace $x$ with $x+\frac\pi3$ :

$-\dfrac\pi4-2n\pi\le x+\dfrac\pi3\le\dfrac\pi4-2n\pi$

$\implies\boxed{-\dfrac{7\pi}{12}-2n\pi\le x\le-\dfrac\pi{12}-2n\pi}$

Dmitry [639]

ANSWER

The probability that someone owns an iPhone or an Apple watch is

$P(I \cup \: A) = 69\%$

or

$P(I \cup \: A) = 0.69$

EXPLANATION

We were given that, the probability that someone owns an iPhone is

$P(I)=62\%$

and the probability that someone owns Apple watch is

$P(A)=15\%$

and the probability that someone owns both is

$P(I \cap \: A) = 8\%$
Since the intersection is not zero, it means the two events are not mutually exclusive.

The probability that someone owns an iPhone or Apple phone is

$P(I \cup \: A) = P(I) + P(A) - P(I \cap \: A)$

We substitute the values to get,

$P(I \cup \: A) = 62\% + 15\% - 8\%$

$P(I \cup \: A) = 69\%$
