15x+40=115
15x means 15 per week solve for x if you want to know how many weeks 40 is what he has only once
48 then 70. Your rule is add 7.
1) 185.16 - 18.99 = 166.17
2) divide 166.17 by 0.87 = 191
3) he drove the truck for 191 miles
Answer: Our required probability is 0.384.
Step-by-step explanation:
Since we have given that
In 24 hours,
λ = 20
In 6 hours,

As we know that it is a Poisson distribution.
E[X] = λ = 5
Probability that more than 6 trucks will pass her apartment is given by

Hence, our required probability is 0.384.
