Answer
The total probability is one:
Total probability of being greater than 25 is 1 because the totals of all values less than 25 is 1.
Considering the scatter plot, the function that best fits the data is given by:
f(x) = 3x².
<h3>What is the function that best fits the data?</h3>
To find the function that best fits the data, we have to look at the scatter plot, which gives a series of points (x,y).
We have that:
- When x increases, y also increases, hence the function is increasing, which removes the option f(x) = -3x.
- The increase looks "faster" than a linear increase, hence a quadratic model should be used, thus removing option f(x) = 3x.
Hence the function that best fits the data is given by:
f(x) = 3x².

The vertex is halfway between 700 and 800, and the x value of the vertex is right over the 10. So since the x value represents dollars, the maximum (vertex) is 10$ each for 750$
The way to get the length of RS is actually very simple. You see how there is a number 17 in the line? You take that and it should mean every area where a line should be is 17. So, R is 17, the 2nd line is 17, M is 17, the 4th line is 17, and S is 17. So you then multiply 17 times 5 and get 85.
