Mean means average.
To find the average, add the data then divide it by the amount of individual data you have.
(6.5 + 5 + 3 + 2 + 2 + 3.5 + 5)/2 = mean
27/2 = mean
13.5 = mean
13.5 miles is the mean distance that Jim jogged.
<span>1. </span><span>The Given problem is to find
where to place the decimal point to the product shown below.
3.9853 x 8.032856, notice that the given equation are decimal numbers with both
ones place value of the whole number.
Now, given the answer 32013341 without decimal point, let’s find where to put
the decimal point.
=> 3.9853 x 8.032856
=> 32.013341
Thus, the decimal point is now located after the 2nd number. We now have 2 whole numbers with value of
tens.

Answer: 72.4 ft
Step-by-step explanation: A2+B2=C2 20squared plus Bsquared=30 22.4 squared plus 20squared equals 30squared and when you add all that together you get 72.4 ft
Answer:
- 10000 people paid $12.00 each for clubhouse seats and
- 26000 people paid $5.00 each for grandstand seats.
Step-by-step explanation:
The question is asking for a system of equations, which make explanations easy. :)
Define the variables. Setting 
to the number of clubhouse seats sold and 
to the number of grandstand seats sold will be sufficient. The "let statement[s]" will be:
- Let be the number of clubhouse seats sold.
- Let be the number of grandstand seats sold.
The number of equations shall be no less than the number of variables for the solution to be unique. There are two variables. It will take at least two equations to find a unique solution.
Everyone at the race need a seat. The number clubhouse seats plus the number of grandstand seats shall be the same as the number people at the race. There were 36,000 people. Therefore the first equation shall be:
.
Every clubhouse seat will add $12.00 to the receipt. clubhouse seats will add $
to the receipt. Similarly, grandstand seats will add $
to the receipt. The two values shall add up to $250,000.
Drop the dollar sign to get the second equation:
.
Hence the system:

.
Solve this system.
The first non-zero coefficient in equation 
is already one. That's the coefficient for . Use multiples of equation to get rid of in other equations (equation 
in this case.)
times equation is
.
Add 
to to get:
.
Divide both sides by -7 to get:
.
Add -1 times this equation to equation to get:
.
That is:
.
In other words,
- 10000 clubhouse seats were sold, and
- 26000 grandstand seats were sold.
