Permutation so 5!/(5-3)!=5!/2!= 5 x 3 x 4= 60 ways.
To find percentage, you take 37.8 and divide it by 63.8 then multiply by 100
(37.8/63.8) × 100 = 59.25%
Answer:
I'm pretty sure it's +(-6).
Step-by-step explanation:
Basically for these, you find the slope. The slope equation is y1-y2/x1-x2.
Pick two points.
I'll just do (1,15) and (2,9).
15-9/1-2 = 6/-1 = -6.
I don't know if you were taught it this way, but my math teacher always told us that the rate of change had to be positive.
So you'd say the rate of change is +(-6), not -6.
Hope that sorta helped lol
