Answer:

  8

Step-by-step explanation:

Since there are 3 (an odd number) ages, the median is the middle one. So, we know two of the ages are 10 and 15. In order for the mean of the three ages to be 11, their total must be 33. The total of the two known ages is 25, so the remaining one must be ...

  33 -25 = 8

The youngest child is 8.

The opening balance of the January billing cycle for Megan's credit card was $4,805 if she makes a new purchase of 300 on the 20
Nookie1986 [14]

Answer:

$4911.45

Step-by-step explanation:

To find Megan's average daily balance, we first need to assume that the billing cycle begins at January 1st.

Now we know that there are 31 days in the month of January, we will use that as our basis.

20 days x 4805 = First 20 days of the billing cycle.

11 days 4805 + 300 = 21st day of the billing cycle.

31 days in the month

So now we simply add the first 20 days and the days after the 21st day and divide it by the number of days in the month since we're looking for the average.

(20 x 4805 + 11(4805+300))/31

(20 x 4805 + 11(5105))/31

(96100 + 56155)/31

152255/31

This then gives us:

$4911.45

You need to put your reindeer, Rudy, Ezekiel, Gloopin, Bloopin, and Prancer, in a single-file line to pull your sleigh. However,
topjm [15]
If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times.  Similarly Rudy and Bloopin will be together 4!=24 times.  So the number of ways they are not together is 120-24-24=72 ways.
