Answer:
11
Step-by-step explanation:
Trapezoid area = (base1 +base2) x h/2
=> Base2 =[Area x 2/h]-base1 = [98.8 x 2/7.6] - 15 = 26-15=11
Exponential growth function is given by f(t) = A(1 + k%)^t; where A is the initial value, k is the growth rate and t is the time period.
Therefore, the required function is
f(t) = 120,000(1 + 0.012)^t = 120,000(1.012)^t
After 15 years, the new population is 120,000(1.012)^15 = 120,000 x 1.1959 = 143,512
Well, first in total there are 16 marbles. So the change of getting a black is 7/16. Now we have 15 marbles. The chance is 6/15. Now we have 14 marbles. The chance is 9/14. When you multiply 7/16 x 6/15 x 9/14 = 9/80
