Answer:

Step-by-step explanation:

Given

x^2 + y^2 - 16y - 36 = 0

x^2 + y^2 - 16y = 36

x^2 + y^2 - 16y + (16/2)^2 = 36 + 8^2

x^2 + (y - 8)^2 = 64 + 36

x^2 + (y - 8)^2 = 100

The center is at (0,8) and the radius is 10

Try and follow it from the graph below.

If both are similar ratio of sides will be same

4.4.3 Quiz: Independence

lbvjy [14]

Answer:

$\frac{2}{15}$

Step-by-step explanation:

<h2><u>Lesson : Probability</u></h2><h2><u></u></h2>

We have a bag with 4 white chips and 6 black chips
Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?

4 white and 6 black

4 + 6 = 10

Choosing the first white chip : $\frac{2}{5}$

Since we took one out , now

3 white chips , 6 black chips

3 + 6 = 9

Choosing another white chip : $\frac{1}{3}$

$\frac{2}{5} * \frac{1}{3}$

$\frac{2}{15}$

How are you supposed to solve this

bagirrra123 [75]

The angle vertically below the 60° must be 120° as their sum must be 180°.

This means the same thing horizontally for our expression...since it is adjacent to a 120° angle its value must be 60° so:

8x-4=60

8x=64

x=8°
