Answer:
30 pounds
Step-by-step explanation:
300/2 = 150
20% of 150 is 30.
You said - 1/3 - 3/5 x = 1/2
Multiply each side by 3 :
- 1 - 9/5 x = 3/2
Multiply each side by 5 :
- 5 - 9x = 15/2
Multiply each side by 2 :
- 10 - 18x = 15
Add 10 to each side :
- 18x = 25
Divide each side by -18 :
<em>x = - 25/18</em>
or x = - 1 and 7/18 (same thing)
That depends. If you have a finite data set, you would add up all the points you have and divide by the total count.
Or, if you are working with pure distributions, the mean is the same as the expected value of the corresponding random variable.
Suppose you have a discrete random variable

with a given probability mass function

, then the mean is given by

which would mean you take all the possible probability for the event that

, multiply each by that

, and add them together.
If the distribution is continuous, say a random variable

that has probability distribution function

over some support

, then the mean is
Answer:
Step-by-step explanation:
13.5/0.75 = 1350/ 75 = 18
As there is no remainder, it means that there is no candy left over. Hence, the answer is A, 0 pounds.
