Answer:
11126
Step-by-step explanation:
The <em>mean</em> of a set of data is another name for its <em>average</em>. It is the sum of the data, divided by the number of numbers in the sum.

If you use a calculator to help you with the computation of the addition or division, you may as well use the calculator's "mean" function to do the job.
The mean of the given 6 values is their sum, divided by 6. The units of the mean are the same as those of the contributors.
(1117 +1409 +675 +536 +1398 +1621)/6 = 6756/6 = 1126 . . . . degrees F
The mean of the data is 1126 °F.
Answer:
Step-by-step explanation:
This is the sum identity for tangent(x + y), where x and y are angles measured in radians. The formula for tan(x + y) is
The first order of business is to find which 2 angles, when expressed in terms of the denominator 12, add up to equal
We will use the first quadrant angles, and only the "important" ones:
When expressed in terms of the denominator of 12, these angles have the equivalent angles, in order from above:
We need to find the 2 whose numerators add up to a 5. That would be:
Remember that
and
so
angle x is and angle y is
, making our tangent sum:
Filling that into our formula for the sum of tan(x + y):
It just so happens that
and
so our formula then becomes
which simplifies to
and then bring up the lower fraction and flip it to multiply giving you:
I have the feeling that you need to rationalize that denominator, and if you do that, the final answer will be:
I know I kind of left you hanging at the very end with rationalizing, but there was so much already that went into this problem in such depth, that I didn't want to risk possibly confusing you even more than I may have already done so. Try and follow the best that you can.
