Answer:
The answer is A so dont waste points
Step-by-step explanation:
The line of best fit is a line that follows the direction of the dots. It doesn't have to be perfect, it's just a general line to represent the data. Sometimes there isn't a line of best fit (if there is no correlation). It normally touches most of the dots.
The slope is about 1/2 and the point where the line touches the y axis is at 40 so that means an equation could be y = 1/2x + 40
When the advertising expenditure (x value) is 18,000, substitute it into the equation above. y = 1/2(18,000) + 40 which equals y = 9,040 . This is the expected revenue.
Hope this helps!
Simple Answer:
Use the x and y coordinates
Step by Step Explanation:
If you are given a table the x-axis is generally on the left/top. Now look at your coordinate plane, the horizontal line is the x and the vertical line is the y. So if you are given (-6,7), you will go to the left 6 and up 7. Hope this helps!
Answer:
She can chose 2 books from 8 books in 28 different way.
Step-by-step explanation:
In the given scenario the member has to chose 2 books from a group of 8 books. The order of choosing books does not matter. For example if the books are A,B,C,D,E,F,G and H, and the member picks books A and B or books B and A, she is picking up the same books. This means order of selection does not matter here, so this is a problem of combinations.
We have to form combination of 8 books taken 2 at a time i.e. 8C2
The general formula of combination is:
Using the values of n=8 and r=2, we get:
This means, she can chose 2 books from 8 books in 28 different ways.
