There are several marbles in a bag: two red, four green, one blue, and five yellow. What is the probability of randomly drawing

a green marble, replacing it, and then randomly drawing a yellow marble?

Answer:

The probability is 5/36

Step-by-step explanation:

The total number of marbles is 2 + 4 + 1 + 5 = 12 marbles

The probability of randomly drawing a green marble would be

number of green marble/total number of marbles = 4/12 = 1/3

Now since we are replacing the total number of marbles stays the same

so, the probability of drawing a yellow marble now will be ;

number of yellow marbles/total number of marbles = 5/12

So the total probability we are having here would be; 1/3 * 5/12 = 5/36

Answer:

x=22

Step-by-step explanation:

According to the Alternate Interior angles theorem, the bottom left angle and the upper right angle have the same measure. Because they were formed from a pair of parallel lines crossed by a transversal one.

So, algebraically:

5x+5=115\\ 5x+5-5=115-5\\ 5x=110\\ \frac{5x}{5}=\frac{115}{5}\\x=22

Solve for the roots in the equation below. In your final answer, include each of the necessary steps and calculations.
Nostrana [21]
x^3-27i=0
x^3=27i
x^3=27e^{i\pi/2}
x=\left(27e^{i\pi/2}\right)^{1/3}
x=3e^{i(\pi/2+2\pi k)/3}
x=3e^{i\pi(4k+1)/6}

where k\in\{0,1,2\}. This means you have

x=3e^{i\pi/6}=\dfrac32(\sqrt3+i)
x=3e^{i5\pi/6}=\dfrac32(-\sqrt3+i)
x=3e^{i9\pi/6}=-3i

as the solutions to the original equation.

If you follow is rule : P(x,y)>180° rotation>P'(-x,-y). the negative signs doesn't mean to make it negative but to change it to the opposite sign. If it's positive it goes to negative. And if it's negative is goes to positive. The rotated image would have the points: (1,2) (4,4) (3,7)

Solve for x: X^2 = 4/16
Rainbow [258]

We know that

x = \sqrt{\frac{4}{16}}

So:

x = \frac{2}{4}
