$|\Omega|=14\\ |A|=4\\\\ P(A)=\dfrac{4}{14}=\dfrac{2}{7} \approx29\%$

There is 14 beads, and out of it there are 4 red ones. You will divide 4 by 14, and get 0.28. 0.28 is equal to 28%

What's the area of this yellow surface? pick one of the options.

28 in^2

Divide shape into one rectangle and two squares:

Area of rectangle:
10 x 2 = 20 in^2

Area of one square:
2 x 2 = 4 in^2

Multiply that by 2 because we have 2 squares similar in size:
4 in^2 x 2 = 8 in^2

Add the area of the rectangle and two squares:
20 in^2 + 8 in^2 = 28 in^2

Have a nice day
Hope this helps!

Which of the following illustrates a phase shift?

Natasha_Volkova [10]

<u>Answer:</u>

A. y = -2 - cos(x-π)

<u>Explanation:</u>

<u>The general form of the trig equation is:</u>

y = A sin (Bx + C) + D

where:

A is the amplitude

$\frac{2\pi}{B}$ is the period

$\frac{-C}{B}$ is the phase shift

D is the vertical shift

<u>Now, let's check the choices:</u>

<u>A. y = -2 - cos(x-π)</u>

$\frac{-C}{B} = \frac{\pi}{1} = \pi$

Therefore, the function has a phase shift of π

<u>B. y = 3 cos(4x)</u>

$\frac{-C}{B} = \frac{0}{4} = 0$

Therefore, the function has no phase shift

<u>C. y = tan(2x)</u>

$\frac{-C}{B} = \frac{0}{2} = 0$

Therefore, the function has no phase shift

<u>D. y = 1 + sin(x)</u>

$\frac{-C}{B} = \frac{0}{1} = 0$

Therefore, the function has no phase shift

<u>Based on the above,</u> the correct answer is A

Hope this helps :)
