Let your number be x
your equation will be (x+11)x = -80
expand the equation x^2 +11x +80 = 0
solve the equation and find x
Answer:
8 13 14 15 18.
Step-by-step explanation:
The median (the middle number) is 14 so we have
x x 14 x x where x is a single number with each number being different (as there is no mode).
The mean is 13.6 so we have the total numbers
= 13.6 * 5 = 68.
The 4 numbers left must total 68-14 = 54 and the difference between the highest and lowest is 10.
I sense that the lowest and highest will add up to about 1/2 of 54 so:
Try 8 and 18 for these last 2 numbers
The list would be 8 x 14 x 18.
The 2 numbers left will add up to 54 - 26 = 28 . One of these must be < 14 and the other > 14. 13 and 15 would fit.
So a possible data set is:
8 13 14 15 18.
Hello! So if your project is turned in late, you get 8/9 of the points you would've received. In this case, you only received 72 points. To find out how many points you lost, first, let's find the score you could've gotten if it was turned in on time. Let's set up a proportion like this: 72/x = 8/9. Cross multiply the values to get 648 = 8x. Divide by 8 to isolate the "x" and you get x = 81. You could've originally gotten an 81. However, you only got a 72. To find out the amount of points you lost, subtract 72 from 81. 81 - 72 = 9. You lost 9 points from your original grade.
