Answer:
Probabilities can be written as fractions, ratios, or as a percentage.
Step-by-step explanation:
If someone asks to flip a coin for heads or tails it has a probability of 1:2, 1/2, or 50% to land on either sides.. They all mean the same value.
Answer:

Step-by-step explanation:
We first translate the statement into an equation:

Then we simplify:

Surface area of the cylinder = 816.4 sq. ft.
Solution:
Height of the cylinder = 21 ft
Diameter of the cylinder = 10 ft
Radius of the cylinder = 10 ÷ 2 = 5 ft
Use the value of
= 3.14
Surface area of the cylinder = 
Substitute the given values in the surface area formula, we get
Surface area of the cylinder 

ft²
Hence the surface area of the cylinder is 816.4 sq. ft.
Answer:
-3
Step-by-step explanation:
Given the function f(x) = -(-x)
we want to evaluate f(-3)
What we do simply here is substitute the value of -3 for x in the equation
That would be ;
f(-3) = -(-(-3)) = -(3) = -3
Answer: Symmetric Property
Explanation: The symmetric property states that x = y, then y = x.
So the symmetric property allows us to
switch the left and right sides of an equation.
