Work out the difference (increase<span>) between the two numbers you are comparing. Then divide the </span>increase<span> by the original number and multiply the answer by 100. If your answer is a negative number then this is a </span>percentage <span>decrease.</span>
Event E is the two numbers are not even.
The complement of event E is the two numbers are even.
The number of outcomes of the complement of event E is 5 * 4 = 20, but since the outcome 2, 4 is the same as the outcome 4, 2, you need to divide the number of outcomes by 2.
Answer: 10
Answer:
Step-by-step explanation:
Triangle
Area = ½ × b × h
b = base
h = vertical height
Square
Area = a2
a = length of side
Rectangle
Area = w × h
w = width
h = height
Parallelogram
Area = b × h
b = base
h = vertical height
Trapezoid (US)
Trapezium (UK)
Area = ½(a+b) × h
h = vertical height
Circle
Area = π × r2
Circumference = 2 × π × r
r = radius
Ellipse
Area = πab
Sector
Area = ½ × r2 × θ
r = radius
θ = angle in radians
If we asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26, and older, it is a type of Discrete variable.
<h3>
What is a Discrete variable?</h3>
- A discrete variable is one whose value can be determined by counting.
- A continuous variable is one whose value can be determined through measurement.
- A random variable is one whose value is the numerical result of a random phenomenon.
- The possible values of a discrete random variable X are countable.
- As an example, It is a type of Discrete variable if we asked people their age and you collected it as 5, 6, 10, 11, 15, 16, 20, 21, 25, 26, and older.
- There are two types of quantitative variables: discrete variables and continuous variables.
- Counts are represented by discrete variables (e.g. the number of objects in a collection).
- Continuous variables represent quantifiable quantities (e.g. water volume or weight).
Therefore, if we asked people to give their age and you collected it as <5, 6-10, 11-15, 16- 20, 21-25, 26, and older, it is a type of Discrete variable.
