Answer:
30 ounces
Step-by-step explanation:
First you have to make the proportion ounces to servings.
Then you put 12 for ounces and 8 for servings.
After you put an equal sign and after the equal sign you put for ounces an x and for servings 1.
Then you put 8x=12.
after you divide 8x by 8 to get x and 12 by 8 to get 1.5.
Lastly you do 1.5 times 20 to get 30.
Answer:
The variance for the number of correct answers is 2.8 questions
Step-by-step explanation:
The number of correct answers follows binomial distribution, in which we have:
- n identical and independents events: the 15 questions
- two possibles results that we call success and fail: The answer is correct and the answer is incorrect
- probability p of success and 1-p of fail. Probability 1/4 of get the answer correct and probability of 3/4 of get the answer incorrect. This probabilities are calculated on that way because every question have 4 possible answers and one of which is correct.
So, the variance for a variable x that follows a Binomial distributions is:
V(x)=n*p*(1-p)
Then, the variance for the number of correct answers is:
V(x)=15*(1/4)*(3/4) = 2.8125 ≈ 2.8
Because n is equal to 15, p is equal to 1/4 and (1-p) is equal to 3/4.
Answer:
9.5%
Step-by-step explanation:
Buying price of the part= $ 8.75
Selling price of the part= $ 9.98
sale tax= $0.40
Selling price before sale tax= $9.98-$ 0.40 = $ 9.58
Make-up amount charged= $9.58- $8.75 = $ 0.83
As a percentage= (0.83/ 8.75) ×100
=9.5%
Answer:
