Answer:2008
Step-by-step explanation:
So in 10 years, the population will double.
8 years is just before doubling to 6800.
If you consider 10 years to be 100% of the doubling time, 8 years is 80%.
And 80 as a decimal is 80/100 = 0.8
So the answer is 0.8 * 6800, simplify.
Answer:
<em>16.08</em>
Step-by-step explanation:
Mean: 10.5 + 16 + 17 + 47 + 49 = 139.5/5 = 27.9
27.9 - 10.5 = 17.4
27.9 - 16 = 11.9
27.9 - 17 = 10.9
27.9 - 47 = 19.1
27.9 - 49 = 21.1
10.9 + 11.9 + 17.4 + 19.1 + 21.1 = 80.4/5 = 16.08
Mean Absolute Deviation: 16.08
Answer:
$ -11.61
Step-by-step explanation:
The expected value in this case would be the subtraction between the probability that the draw will win for its value (the prize + value of the ticket) and the value of the ticket for the probability of not winning the draw, thus:
(1/810) * (1100 + 13) - (809/810) * (13)
1,374 -12,984 = -11.61
which means that the expected value is $ -11.61
