Answer:

1/20, 0.05, 5%

Step-by-step explanation:

There are 20 total possibilities, so you choosing one of them has a 1/20 chance. For example, If you had numbered the balloons, and you wanted to pick a red one with the number 3 on it, there would be a 1/20 chance. 1/20= 0.05, which also equals 5%

Hope this helps!

Type the correct answer in each box. The length of a rectangle is 2 inches more than its width. The perimeter of the rectangle i
Reika [66]

Step-by-step explanation:

The equation that represents the perimeter of the rectangle is given as;

2x + 2(x + 2) = 24 where x represents the width.

We solve for x;

2x + 2x + 4 = 24

4x + 4 = 24

4x = 24 - 4

4x = 20

x = 20/4

x = 5

We were informed that the length of the rectangle is 2 inches more than its width. This implies that the length is x+2 = 5+2 = 7.

The value of x from the set {1, 3, 5, 7} that holds true for the equation is 5. So, the width of the rectangle is 5 inches and its length is 7 inches.

Find all possible values for each expression. sin^-1 1/2 a. 30° + 180n, 150° + 180n b. 30° + 360n, 150° + 360n c. 60° + 180n, 12
BartSMP [9]

Answer:

Option B.

Step-by-step explanation:

The given expression is

\sin^{-1}\left(\dfrac{1}{2}\right)

It can be written as

\sin^{-1}\left(\dfrac{1}{2}\right)=\sin^{-1}\left(\sin (30^\circ\right)    [\because \sin (30^\circ)=\dfrac{1}{2}]

\sin^{-1}\left(\dfrac{1}{2}\right)=30^\circ

We know that sin is positive in first and second quadrant.

For first quadrant,

\theta=30^\circ

For second quadrant,

\pi-\theta =180-30=150^\circ

So, the required angles are 30^\circ+360n,150^\circ+360n.

Therefore, the correct option is B.
