Answer:

Yes and Yes

Step-by-step explanation:

Simply put, a z-score (also called a standard score) gives you an idea of how far from the mean a data point is. But more technically it's a measure of how many standard deviations below or above the population mean a raw score is. A z-score can be placed on a normal distribution curve.

If the radius of the circle is 3 in, what is the area of the circle?
murzikaleks [220]

The area of the circle is 28.26 in²

<u>Explanation:</u>

Given:

Radius of the circle, r = 3 in

Area of circle, A = ?

We know:

Area of circle = πr²

The value of π is 3.14

Thus,

A = 3.14 X (3)²

A = 3.14 X 9

A = 28.26 in²

Therefore, the area of the circle is 28.26 in²

Over the interval [0,2pi), what are the solutions to cos(2x) = cos(x)? check all that apply​
kykrilka [37]

\cos(2x)  =  \cos(x)

Solution (1)

2x = x + 2k\pi

2x - x = 2k\pi

x = 2k\pi

for k=0 / for k=1 / for k=-1

x=0 / x=2π / x=-2π

acc / acc / rej

solution (2)

2x =  - x  + 2k\pi

2x + x = 2k\pi

3x = 2k\pi

x =  \frac{2k\pi}{3}

for k=0 / for k=1 / for k=-1

x=0 / x=2π/3 / x=-2π/3

acc / acc / rej

Note that i'm trying values of K which make the answer belong to our interval;

So our solution which i will represent as a set is;

S € {0,2π/3,2π}
