Answer:
True
Step-by-step explanation:
We use definitions to help us in this problem. The definition of an integer is a whole number that is not a fraction or has any fractional value. This definition includes all whole numbers, so we know that all whole numbers can be classified as integers. That's one condition done. The definition of a rational number is a number that can be written as a fraction. All whole numbers can be written as a fraction (i.e. 12/1, -3/1, 10000/1). This means that all whole numbers are also rational numbers, giving us our final answer of True.
FINAL ANSWER: True
Answer:
Variance σ² having standard deviation 2.5 is 6.25.
Step-by-step explanation:
The standard deviation is basically the square root of the variance.
So, if want to find the variance of the data we simply take square of standard deviation to get the variance of data.
standard deviation = σ = 2.5
taking square on both sides
(σ)² = (2.5)²
σ² = 6.25
So, variance σ² having standard deviation 2.5 is 6.25.
