Unit price would be the price per ounce.
Divide the total cost by the number of ounces:
Price Club : 2.59 / 12 = $0.216 per ounce
Shop Mart: 1-1/2 pounds = 1.5 x 16 = 24 ounces.
4.68 / 24 = $0.195 per ounce.
Answer:
Step-Question: The amount of money spent weekly on cleaning, maintenance, and repairs at a large restaurant was ...
The amount of money spent weekly on cleaning, maintenance, and repairs at a large restaurant was observed over a long period of time to be approximately normally distributed, with mean ? = $615 and standard deviation ? = $38.
(a) If $646 is budgeted for next week, what is the probability that the actual costs will exceed the budgeted amount? (Round your answer to four decimal places.)
(b) How much should be budgeted for weekly repairs, cleaning, and maintenance so that the probability that the budgeted amount will be exceeded in a given week is only0.08? (Round your answer to the nearest dollar.)
$by-step explanation:
There are 4 possibilities out of the 36 ways the dice can land:
... (3, 3), (3, 6), (6, 3), (6, 6)
Hence, the probability of an outcome in this set is 4/36 = 1/9.
Answer: 32
Step-by-step explanation:
Answer:
a) 
With:
b) 
c) 
d) 
Step-by-step explanation:
For this case we know the following propoertis for the random variable X
We select a sample size of n = 81
Part a
Since the sample size is large enough we can use the central limit distribution and the distribution for the sampel mean on this case would be:
With:
Part b
We want this probability:
We can use the z score formula given by:
And if we find the z score for 89 we got:
Part c
We can use the z score formula given by:
And if we find the z score for 75.65 we got:
Part d
We want this probability:
We find the z scores:
