Part A
There are 2 cups in a pint, so 2 x 3 = 6
Plus 5 cups,
1 quart is equal to 1/4 of a gallon, and there are 4 cups in a gallon,
and another quart is 4 more cups,
so add all of the cups together:
6 + 5 + 4 + 4 = 19
Kelly is incorrect, because I added all of the cups together and I got 19.
Part B
Since 4 cups fit in a quart, and she has 4 quarts, her quarts only hold 16 cups, which isn't enough, because there are 19 cups.
Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)
Answer:
$127.5
Step-by-step explanation:
15% of $850 is 850 times .15 (% is decimal multiplied by 100)
850 * .15 = $127.50

Answer:
(a)
(b)
-1
(c)
30
Step-by-step explanation:
(a)
Your random variable will have two possible values, 30 and 0, one of them with a probability of 0.45 and the other one with a probability of 0.55. Therefore it looks like this.
(b)
The expected value of this PMF would be
![E[X] = -10*0.55+10*0.45= -1](https://tex.z-dn.net/?f=E%5BX%5D%20%3D%20-10%2A0.55%2B10%2A0.45%3D%20-1)
therefore on average you will have a dollar less.
(c)
For this one, if you play 20 times and your initial amount is 50$ then you have to compute the following expectation.
![E[50+20*X] = 50+20*E[X] = 50-20 = 30](https://tex.z-dn.net/?f=E%5B50%2B20%2AX%5D%20%3D%2050%2B20%2AE%5BX%5D%20%3D%2050-20%20%3D%2030)
