Answer:
percentage increase in Kristen's average score is = 25%
Step-by-step explanation:
Given:-
- The last year score, Si = 84 points
- This year score, Sf = 105 points
Find:-
What is the percent of increase in Kristen's average score?
Solution:-
- We are to determine the percentage increase in Kristen's average score from last year.
- The relation to develop percentage increase "%inc" is given by:
%
- plug in the values:
- The percentage increase in Kristen's average score is = 25%
For continuously compounded interest:
Amount = Principle * e^(rate * time)
A rate of 8% converted to a decimal value: r=0.08
With time t=4
and amount 1190
Plug all these values in,
1190 = Principle * e^(0.08 * 4)
And use your calculator to solve for the principle.
Maybe we'll call it P to make things easier.
1190 = P * e^(0.08 * 4)
1190 = P * 1.377
The principle is being multiplied by this 1.377,
divide by 1.377 to undo the multiplication.
864.11735 = P
The bottom right.
The line best fit is usually the line that follows the trend of dots in the scatter plot. In the other 3, you can tell that there seems to be no trend between either the line or the dots.
The bottom right one has a line pretty much right through the middle of the scattered dots and follows the trend.
Yes because the median and range are not a function of the totality of the sample set, the median is just value that is halfway of the set.
Hope this helps :)
