Answer:
it has been found that 85.6% of all enrolled college and university students in the U.S. are undergraduates. A random sample of 500 enrolled college students in a particular state revealed that 420 of them were undergraduates. Is there sufficient evidence to conclude that the population differs from the national percentages? Use a = 0.05
First, we need to calculate the cost of the sale tax. To do it, we are going to convert the sale tax from percentage to fraction by dividing it by 100, and then we are going to multiply the cost of the DVD by the sale tax:
Now, we can multiply the cost of the DVD by the sale tax to find the cost of the sale tax:
Now that we know that the sale tax is $1.26, we are going to add the cost of the sale tax to the cost of the DVD and check if that sum is less or equal than Torri's money (20$):
Since $19.26
$20, we can conclude that Torri has enough money to buy the DVD. In fact, Torri will end with a change of $0.74 after buying the DVD.
The answer to the above question is three
Third answer, or c. (b+8>or equal to 12.4)
The bill is issued on the 3rd.
It is due 8 days later, this means that it is due on the 11th.
There is a one day grace period.
Since Frank paid the bill on the 12th, this means that his payment is received after the deadline. However, he will not be charged for any extra fees as he was still in the grace period when he paid.
