Information given to us:
10 4/5 total cake batter
18 cupcakes
First, we need to find the improper fraction of 10 4/5, which is 54/5. Now we can divide 54/5 by 18. Answer: every cupcake will use 3/5 cup.
4 less than five times a number is -11:
5x - 4 = -11
First we need to find the total amount of servings needed.
(x2) 12 servings/5 people (x2)
24 servings/10 people
Now we can find the amount of pans needed
24 servings/8 servings (1 pan)
=3 pans
She needs at least 3 pans
I believe the sum of the root is: -3/2
And the product of the root is: 0
I hope this helps and have a great week :)
Answer:
Step-by-step explanation:
a. The hypothesis test is one tailed_____ test.
(Because we check whether sample weight is greater than hence one tailed or right tailed)
The test statistic follows a __t___ distribution.(Because only sample std deviation s is known)
The value of the test statistic is___Mean difference/Std error =
__
b. df = 66
Reject H0 if t ≥ 1.668
c. The p-value is_____0.059444
d. Using the critical value approach, the null hypothesis is _accepted____, because __t <1.668___ Using the p-value approach, the null hypothesis is__accepted___, because__p value <0.05 our significance level.___ Therefore, you __may___ conclude that the mean weight of the airline's passengers' carry-on items has increased after the implementation of the checked-bag fee.
