Cristian, Iris, and Morgan each get an equal share of; of a pizza. Which model represents the fraction of the pizza each person
gets?
1 answer:
Answer:
Each person receives a third of the entire pizza. (Please see image attached below)
Step-by-step explanation:
If Christian, Iris and Morgan receive an equal share of a pizza and a pizza has a value of 1. Then, each person receives a third of 1. That is:
Lastly, a graphic representation of the fraction of the pizza each person receives is shown below as attachment.

Answer:
And we can find this probability using the normal standard distribution or excel and we got:
Step-by-step explanation:
For this case we assume the following complete question: "The pucks used by the National Hockey League for ice hockey must weigh between 5.5 and 6 ounces. Suppose the weights of pucks produced at a factory are normally distributed with a mean of 5.86 ounces and a standard deviation of 0.13ounces. What percentage of the pucks produced at this factory cannot be used by the National Hockey League? Round your answer to two decimal places. "
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution or excel and we got:
