9 students
30% ends up being .3%, multiply .3% by 30 students which equals 9.
Answer:
D) a8 = 35 - (n - 1)(3)
Step-by-step explanation:
Answer:
Here we have the function:
S(t) = 500 - 400*t^(-1)
Then the rate of change at the value t, will be:
S'(t) = dS(t)/dt
This differentiation will be:
S'(t) = -400/t^2
Then:
a) the rate of change at t = 1 is:
S'(1) = -400/1^2 = -400
The rate of change after one year is -400
b) t = 10
S'(10) = -400/10^2 = -400/100 = -4
The rate of change after 10 years is -4, it reduced as the years passed, as expected.
All you have to do is find the total amount he wrote out checks for and then subtract that from $259.68. The answer is $99.03
The combination formula is given by
C(n, r) =
C(11, 8) =
C(11, 8) = 165
So, there are 165 ways of choosing 8 flowers out of 11 flowers
