Answer:
Relative Frequency Method
Step-by-step explanation:
If I carry out an experiment involving 25 throws of a coin and I obtain 13 Heads(H), the Relative Frequency of obtaining Heads will be 13/25.
Now if I intend to find out approximately how many Heads will
occur in 300 throws, I simply use the result or experimentation data that I have.
This is done below:
Relative Frequency of Obtaining a Head= 13/25 =0.52
Number of Heads obtained in 300 throws
= Relative Frequency X Number of Trials
=0.52 X 300
=156
This is an example of how relative frequency method works.
8/-3 ÷ -4/9
8/-3 * 9/-4
72/12 = 6
Answer:
-3y/5
Step-by-step explanation:
3/5y+(-6/5y)=
Since the denominator is the same, we can add the numerators
3y - 6y
----------------
5
-3y/5
Answer:
72
Step-by-step explanation:
it would be 72 because your adding 56+16 and that equals 72 numbers he will use
Short answer: r = 8
Remark
The easiest way to do this is to solve the sphere's volume in terms of pi. When you do this, you can equate that to the formula for a cylinder and cancel the pi values.
Step One
Find the volume of the sphere.
<em>Givens</em>
r = 6 cm
<em>Formula</em>
V = (4/3) pi r^3
<em>Sub and Solve</em>
V = 4/3 pi * 6^3
V = 288 * pi
Step two
Find the radius of the cylinder
<em>Givens</em>
V = 288* pi cm^3
h = 4.5 cm
<em>Formula</em>
V = pi r^h
<em>Sub and solve</em>
288 pi cm^3 = pi r^2 * 4.5 Divide both sides by pi
288 cm^3 = 4.5 r^2 Divide both sides by 4.5
388 / 4.5 = r^2
64 = r^2 Take the square root of both sides.
r = square root( 64)
r = 8 <<<<< Answer
