Answer:
18.88% probability that three or four customers will arrive during the next 30 minutes
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
Average rate of 6.4 per 30 minutes.
This means that 
What is the probability that three or four customers will arrive during the next 30 minutes?
18.88% probability that three or four customers will arrive during the next 30 minutes
Every hour there is 15 gallons of water added to the tank. In 10 hours there will be 150 gallons of water in the tank.

The distance from point H to point J is 3 units.The value of n is 3.
Step-by-step explanation:
From the graph, point H is at (n,-6)
Point G location will be at (0,-6)
Point J is at (n,-3)
Observing point H(n,-6) and point J (n,-3) you notice that point J is above point H.find how much far is point H from point J.
d= √(x₂-x₁)²+(y₂-y₁)²
d=√(-3--6)²
d=√3² =√9 = 3
Distance H to J is 3 units
Point G (0,-6) and point H (n,-6) have a distance of 3 units same as point H to J
To get the horizontal length will ;
d=√ (n-0)²
d=√n² but d=3 units
3=√n²
9=n²
√9=n
3=n

Answer:
$135
Step-by-step explanation:
6.75 x 5 = 33.75 (to find the amount of money he earned each night)
