Answer:
0.381 is the probability that the number of drivers will be at most 18.
Step-by-step explanation:
We are given the following information in the question:
The number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20.
- The Poisson distribution is the discrete probability distribution of the number of events occurring in a given time period, given the average number of times the event occurs over that time period.
- The variance of Poisson distribution is equal to the mean of Poisson distribution.
a) P(number of drivers will be at most 18)
Formula:


Thus, 0.381 is the probability that the number of drivers will be at most 18.
Answer:
$44.31
Step-by-step explanation:
Regular Price = $42
Sales Tax Rate = 5 1/2% or 5.5%
The total cost would be the regular price PLUS the sales tax. We find the sales tax by finding 42's 5.5%.
First, converting percentage to decimal (dividing by 100):
5.5% = 5.5/100 = 0.055
Now finding 5.5% of $42:
42 * 0.055 = $2.31
Now, the total price is the SUM of regular and this sales tax:
Total Price = 42 + 2.31 = $44.31
Hello!
4 (x-12) ^ 1/3 = -16
Step 1. Simplify each side of the equation, 4/
3x + −16 = −16 and 4
/3
x −16 = −16
Step 2. Add 16 to both sides, 4
/3
x − 16 + 16 = −16 + 16
Step 3: Multiply both sides by 3/4, (
3/4)*(4/3x)=(3/4)*(0)
Final Answer: x= 0
Hope I could help! :)
Answer:
Julio's number is 212
Step-by-step explanation:
(x - 12) ÷ -5 = -40
x - 12 = -40 times -5
x - 12 = 200
x = 200 + 12
x = 212
Check:
(x - 12) ÷ -5 = -40
((212 - 12)) ÷ -5 = -40
200 ÷ -5 = -40
-40 = -40
