Or positive values up to 5
2*5=10-1=9
Answer: 0.0497870 ; 0.87754
Step-by-step explanation:
Given that :
λ = 0.0003
Defining a continuous distribution function :
F(x) = 1 - e^-λx = 1 - e^-0.0003x ; x ≥ 0
a. What proportion of the fans will last at least 10,000 hours?
P(x ≥ 10000) = e^-0.0003(10000) = 0.0497870
b. What proportion of the fans will last at most 7000 hours?
P(x ≥ 7000) = 1 - p(x ≤ 7000) = 1 - e^-0.0003(7000)
1 - 0.12245642825 = 0.87754
Dividing integers is the opposite of multiplying integers.

Answer:
3440
Step-by-step explanation:
The total number of people polled is 150.
The total number of people who said they'd vote for Candidate #2 is 78.
The number of undecided voters is 7.
Assuming undecided voters don't vote, Candidate #2 can expect to win 78/143 = 54.5% of the votes.
75% of the 8400 registered voters will vote, or 6300.
So Candidate #2 can expect to win 3440 votes.
