The gfc of 24 and 30 is 6.
The apples are x and cost $1, and the grapefruits are y and cost $2.
So, 1x and 2y
These together must equal $16
1x + 2y = 16
Hope this helped :)

Poisson Distribution
There are two main characteristics of a Poisson experiment.
The Poisson probability distribution gives the probability of a number of events occurring in a fixed interval of time or space if these events happen with a known average rate and independently of the time since the last event. For example, a book editor might be interested in the number of words spelled incorrectly in a particular book. It might be that, on the average, there are five words spelled incorrectly in 100 pages. The interval is the 100 pages.
The Poisson distribution may be used to approximate the binomial if the probability of success is “small” (such as 0.01) and the number of trials is “large” (such as 1,000). You will verify the relationship in the homework exercises. n is the number of trials, and p is the probability of a “success.”
The random variable X = the number of occurrences in the interval of interest.
The average number of loaves of bread put on a shelf in a bakery in a half-hour period is 12. Of interest is the number of loaves of bread put on the shelf in five minutes. The time interval of interest is five minutes. What is the probability that the number of loaves, selected randomly, put on the shelf in five minutes is three?
- Let X = the number of loaves of bread put on the shelf in five minutes. If the average number of loaves put on the shelf in 30 minutes (half-hour) is 12, then the average number of loaves put on the shelf in five minutes is \left(\frac{5}{30}\right)(12) = 2 loaves of bread.
The probability question asks you to find P(x = 3)
The answer would be about 93 km in length.
Answer:
0.035547
Step-by-step explanation:
We would be using z score formula to solve for this question
The formula for calculating a z-score is is
z = (x-μ)/σ
where x is the raw score = 18 in
μ is the population mean = 10.6 in
σ is the population standard deviation = 4.1 in
z score = 18 - 10.6/ 4.1
z score = 7.4 /4.1
z score = 1.80488
Using the normal distribution table to find the probability for the z score of 1.80488
Probability value from Z-Table:
P(z = 1.80488) = 0.96445
The probability that a fish caught there will be longer than 18 in is calculated as:
P(x>18) = 1 - P(z = 1.80488)
= 1 - 0.96445
= 0.035547
