Answer:
-5≤y≤-1
Step-by-step explanation:
The range is the values that y takes
The smallest value of y is -5 and the largest value of y is -1
-5≤y≤-1
The variance of a distribution is the square of the standard deviation
The variance of the data is 2.2
<h3>How to calculate the variance</h3>
Start by calculating the expected value using:

So, we have:

This gives

Next, calculate E(x^2) using:

So, we have:


The variance is then calculated as:

So, we have:


Approximate

Hence, the variance of the data is 2.2

Answer:
A. 3
Step-by-step explanation:
In a function, the inputs do not repeat.
The inputs are assigned to exactly one output for each.
Three is one of the options. Three is already an input in the given function.
Replacing the ? with 3 would create the non-function.
(3,5) (2, 4) (9, 0) (3,6)
Option A should be the correct answer.
Hope this helps.
