Answer:
10
Step-by-step explanation:
The current probability of picking a red ball is 
. When 5 more balls are added, the probability is 3/4. We can write a ratio for this problem:
When using cross multiplication to solve this, you get 3 * 20 = 4(x+5).
60 = 4x + 20
40 = 4x
x = 10 red balls
Answer:
6, 8, 10, 12, 18, 20
Mean: 6 + 8 + 10 + 12 + 18 + 20 = 74/6 = <em>12.3</em>
Median: <em>11</em>
Mode: <em>there are no mode in the following listed numbers or data set.</em>

Answer:
<em>The correct option will be: (b) 7 feet.</em>
Step-by-step explanation:
Suppose, the length of the garden is 
feet.
As the <u>shape of the garden is like a square, then the area of the garden</u> will be: 
feet²
Given that, the <u>area is 52 square feet</u>. So, the equation will be.......
So, the approximate length of the garden will be 7 feet.
Answer:
49.735919716217
Step-by-step explanation:
Area =
C2 / 4π
The product of a non-zero rational number and an irrational number is irrational.
Therefore C is the answer.
A, B, and D are all properties of rational numbers. Irrational numbers are ones that can not be written as a ratio, or fraction, using whole numbers. They are non-repeating, non-terminating numbers. Example would be pi.
