yKpoI14uk [10]

Answer:

168 in 7 hours.

Step-by-step explanation:

We can't multiply.

We got to count up by 12's for each 1/2 hour.

12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168.

Simplified:

24, 48, 72, 96, 120, 144, 168.

Estimate:

12 = 1/2 hour
24 = 1 hour
36 = 1 1/2 hours
48 = 2 hours
60 = 2 1/2 hours
72 = 3 hours
84 = 3 1/2 hours
96 = 4 hours
108 = 4 1/2 hours
120 = 5 hours.
132 = 5 1/2 hours
144 = 6 hours
156 = 6 1/2 hours
168 = 7 hours.

Answer is 168.

A rare form of malignant tumor occurs in 11 children in a million, so its probability is 0.000011. Four cases of this tumor occ

Shkiper50 [21]

Answer:

a) The mean number of cases is 0.14608 cases.

b) The probability that the number of cases is exactly 0 or 1 is 0.990.

c) The probability of more than one case is 0.010

d) No, because the probability of more than one case is very small

Step-by-step explanation:

We can model this problem with a Poisson distribution, with parameter:

$\lambda=r*t=0.000011*13,280=0.14608$

a) The mean amount of cases is equal to the parameter λ=0.14608.

b) The probability of having 0 or 1 cases is:

$P(k=0)=\frac{\lambda^0 e^{-\lambda}}{0!}=\frac{1*0.864}{1} =0.864\\\\ P(k=1)=\frac{\lambda^1 e^{-\lambda}}{0!}=\frac{0.14608*0.864}{1} =0.126\\\\P(k\leq1)=0.864+0.126=0.990$

c) The probability of more than one case is:

$P(k>1)=1-P(k\leq 1)=1-0.990=0.010$

d) The cluster of 4 cases can not be due to pure chance, as it is a very high proportion of cases according to the average rate. Just having more than one case has a probability of 1%.
