EZ: two rectangles and one triangle :P
15*4 + 10*3 + 3*4/2 = 60+30+6 = 96 ... nice number
Answer:
First we need to set up a table, i'll make up some numbers.
y= 2,4,6,8
x=4,8,16,20
x is always over y.
the y values go up 2 each time, and the x values go up 4 each time.
so your format would be y=mx+b
your answer from my example would be y=2x+4.
also i forgot about the your answer for that would be the number it counts up or down by each time, and our answer for this would be
I hope this helps!
Hello from MrBillDoesMath!
Answer:s:
For #18, see attachment, "Scatterplot_18", where the data is plotted. It looks like choice J -- no association-- is the correct answer.
For #14 it looks like you had some confusion but are on the right track. The formula for compound interest is Amount = P(1+r)^n, where P if the Principal (initial investment), r is the yearly rate, and "n" is the number of years invested. In your case,
A = 1000 ( 1 + .02)^3 => as 2% = 2/100 = .02; n = 3 as money
invested for three years
A = 1000 (1.061208) =
$1061.21
This is the same answer you got but is NOT one of the choices. Hmmm.....
Thank you,
MrB
