Answer:
a) Cancellations are independent and similar to arrivals.
b) 22.31% probability that no cancellations will occur on a particular Wednesday
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.
Mean rate of 1.5 per day on a typical Wednesday.
This means that
(a) Justify the use of the Poisson model.
Each wednesday is independent of each other, and each wednesday has the same mean number of cancellations.
So the answer is:
Cancellations are independent and similar to arrivals.
(b) What is the probability that no cancellations will occur on a particular Wednesday
This is P(X = 0).
22.31% probability that no cancellations will occur on a particular Wednesday
(3,-1) pls thank me lol it makes me put 20 characters
Answer:
- 14x + 14
Step-by-step explanation:
- 10 - 11x + 24 - 3x ← collect like terms
= (- 11x - 3x) + (- 10 + 24)
= - 14x + 14
Answer:
D
Step-by-step explanation:
When you are raising something to a fractional power, you are raising it to the power of the numerator and finding the root denoted by the denominator. The explanation above is kinda confusing, so here is an example:
x^(3/5)
This would be written as:
Now for the actual problem. Since the numerator is 4, we start by raising x to the 4th power, x^4.
Because the denominator is 5, we find the 5th root:
This matches none of the answers shown, so the answer is none of the above or D.
Using the line of best fit drawn on the graph, I can estimate from the graph that the possible bank balance is $160.
