simple interest:
principal x ( 1 + (rate as decimal x number of years))
example if you put 100 dollars in a bank for 5 years at 5% interest at the end of the 5 years you would have:
100 x (1+(0.05 x 5)) = 100 x (1+(0.25)) = 100 x 1.25 = 125 dollars
125-100 = 25 dollars interest
Slope is 2/5 and the y into is -1/3
I just went with the slope. So I am not sure about the y-int.
Slope= y2 -y1 over x2-x1
(-2/15–1/30) =-.1
—————————- (over)
(-1/2- -3/4) =. -.75
- 0.1 / - 0.25 = .4 = 2/5
1,2,2,2,3,3,3,3,4,4,4,4,5 are all the test scores. if you add them all up, its 40, and there are 13 numbers in the data set, so you divide 40 by 13, and you get 3.07692 overscore, or 3 and 10/13
Answer:
If the two beside the p in d is an exponent I believe that would be correct. if not sorry
