(1) FOUR LESS THAN THE PRODUCT OF 4 AND A NUMBER is 4x - 5 = 5
(2) THE PRODUCT OF FOUR AND THE DIFFERENCE OF A NUMBER AND FIVE is 4 (x-5)
(3) THE PRODUCT OF FOUR AND THE SUM OF A NUMBER AND FIVE is
4 (x+5)
Answer:


So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10
Step-by-step explanation:
Let X the random variable that represent the number of rookie cards of a population, and for this case we know the distribution for X is given by:
Where
and
We select a sample size of n = 10 variety packs and we want to find this probability:
We can use the z score formula given by:
If we apply this formula to our probability we got this:
We can find the z score for 2 and 4 and we got:


So we can find the probability with this difference
And using the normal standard distirbution or excel we got:
So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10
The x-coordinate remains the same.
The y-coordinate was 5, above the x-axis, now it becomes -5, below the x-axis.
Answer: (3, -5)
