Answer:
If a Poisson process applies, we have the probability that k potholes are find in t miles as:
The probability that no more that one pothole will appear in a section of one mile is P=0.1353.
The probability that no more that 4 potholes will occur in a given section of 5 miles is P=0.0293.
Step-by-step explanation:
We have the rate of potholes:
If a Poisson process applies, we have the probability that k potholes are find in t miles as:
The probability that no more that one pothole will appear in a section of one mile is P=0.1353:
The probability that no more that 4 potholes will occur in a given section of 5 miles is P=0.0293:
To find 20% of 950 you would set it up as a proportion. When doing percentages the prevent is always out of 100 so the first step would be 20/100. You are trying to find a number out of 950 so the second part would be ?/950. Now you want to cross multiply and divide. 20*950=19,000 then you divide it by 100 (your other number) 19,000/100=190. So 20% of 950 is 190.
He can buy 4
35($ to spend)-25(Admission price)= 10 (Money for drinks)
10/2.50(Drink price) = 4
1 BAG= 4/6 days which is 2/3
4 BAGS= 6 days
? BAGS= 9 days
9 days =2/3 X 9 days
therefore 2 X 3 =6 BAGS
therefore 6bags = 9days
