Howdy there! ;) The answer to your question is 0.75. I got the answer because you divide 15 and 20( 15/20) So simplify if you want to. 15/5=3 20/5=4 equals 3/4 there are 4 25's in a hundred 25,50,75,100 so since 3/4 is three then it would be 0.75.

Hope I helped! :D

Answer:

$B_2=4\pi r^2$

see the explanation

Step-by-step explanation:

we know that

The area of the base of a cylinder is given by the formula

$B=\pi r^{2}$

where

r is the radius of the circular base

If the radius is doubled

then

$r=2r$

The new base area is

$B_2=\pi (2r)^{2}$

$B_2=4\pi r^2$

$B_2=4B$

therefore

The new area of the base is 4 times the area of the original base

Gitta is asked to find the probability of getting all heads on 3 coin tosses. This is a compound event.

DedPeter [7]

1. P(getting all head)= $\frac{n(getting-all-head)}{n(Sample-space)}$

2. Event: getting all head can happen in only one way: HHH

3. n(Sample space) can be calculated by

a. counting, a good ways to organize counting is drawing a tree diagram, CHECK THE PICTURE

or
b. There are 2 possible outcomes each time we throw the dice so 2*2*2=8 is the total number of outcomes, that is the number of the sample space.

4. So finally P(getting all head)= $\frac{1}{8}$
