What is the volume of the composite figure?

saw5 [17]

volume of a sphere is 4/3 * PI * r^3

r = 6

r^3 = 6^3 = 216

4/3 * 216 = 288

Volume = 288 PI in^3

For a certain experiment, if we expect to get a red marble twelve times in 60 trials, what is the theoretical probability of get

MrRa [10]

Answer:

1/5

Step-by-step explanation:

You expect to get 12 red marbles out of 60 trials.

So, you expect to get a red marbles 12/60 of the times.

We can simplify that 12/60 to 1/5, which is a choice of answers. :-)

We assume here you correctly assume your probability level when you did your forecast of 12/60. And either you're picking from a small pool and re-insert the marble, or you have a very large amount of marbles (at least 60).

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point A(3, 8)

Point B(-1, 1)

Step 2: Find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1 - 3)^2 + (1 - 8)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-4)^2 + (-7)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{16 + 49}$
[√Radical] Add: $\displaystyle d = \sqrt{65}$
