Using it's concept, the standard deviation of the data-set is of 34.2.
<h3>What are the mean and the standard deviation of a data-set?</h3>
- The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.
- The standard deviation of a data-set is given by the <u>square root of the sum of the differences squared between each observation and the mean, divided by the number of values</u>.
Having this in mind, and inserting the data-set in the calculator, it is found that:
- The standard deviation is of 34.2.

Answer:
Blank 1: 3
Blank 2: 6
Step-by-step explanation:
When doing the X method, the numbers on the sides(3 and 6) have to add up to the number on the bottom (9) and multiply to get the number on the top(18)
Answer: D. The range stays the same, but the domain changes.
Step-by-step explanation: A function can be reflected over or across an axis. When the function is reflected in the y-axis, it means:
g(x) = f(-x)
i.e, the x-values are opposite to the original function.
In the image below, when we reflected the function across the y-axis, the new one will be drawn at the positive x-axis but still at the negative y-axis as shown in red at the second attachment.
<u>Domain</u> of a function is all the values x can assume. <u>Range</u> of a function is all the results the variable y assume.
According to the new graph, <u>y-values didn't change, so Range stays the same. However, x-values changed their signal. Therefore, domain changes.</u>
The question is defective, or at least is trying to lead you down the primrose path.
The function is linear, so the rate of change is the same no matter what interval
(section) of it you're looking at.
The "rate of change" is just the slope of the function in the section. That's
(change in f(x) ) / (change in 'x') between the ends of the section.
<u>In Section A:</u>
Length of the section = (1 - 0) = 1
f(1) = 5
f(0) = 0
change in the value of the function = (5 - 0) = 5
Rate of change =
(change in the value of the function) / (size of the section) = 5/1 =<em> 5</em>
<u>In Section B:</u>
Length of the section = (3 - 2) = 1
f(3) = 15
f(2) = 10
change in the value of the function = (15 - 10) = 5
Rate of change =
(change in the value of the function) / (size of the section) = 5/1 = <em> 5
</em><u>Part A:</u>
The average rate of change of each section is 5.
<u>Part B:</u>
<span><span>The average rate of change of Section B is equal to
t</span>he average rate of change of Section A.
<u>Explanation:</u>
The average rates of change in every section are equal
because the function is linear, its graph is a straight line,
and the rate of change is just the slope of the graph.

It would be 7/2. Its basically subtraction a whole number then two numerators.
