Answer:
The equivalent expression
Step-by-step explanation:
Assuming your expression is , then we can use the power property of logarithm , which is
.
If we let a=15, b=2, and n=3
Then using the power property of logarithm will give us:
Using the power property of logarithm, the equivalent expression is
Answer:
Step-by-step explanation:
Given that a fisherman catches fish according to a Poisson process with rate lambda = 0.6 per hour.
The fisherman will keep fishing for two hours.
Since he continues till he gets atleast one fish, we can calculate probability as follows:
(a) Find the probability that he stays for more than two hours.
= Prob (x=0) in I two hours and P(X≥1) in 3rd hour
=P(x=0)*P(X=0)*P(X≥1) (since each hour is independent of the other)
=
(b) Find the probability that the total time he spends fishing is between two and five hours.
Prob that he does not get fish in I two hours * prob he gets fish between 3 and 5 hours
=
(c) Find the expected number offish that he catches.
Expected value in Geometric distribution = , where p = prob of getting 1 fish in one hour
=
(d) Find the expected total fishing time, given that he has been fishing for four hours.
= Expected fishing time total/expected fishing time for 4 hours
=3/0.6*4
= 1.25 hours

so.. whatever the parabola y= -3x²+k is, will pass over (3,-2) and (-3,-2)
so.. .let us pick say hmmm 3,-2
thus
solve for "k"
