Subtract 1.400 from 64.521 and you get 63.121.
15=-2(2t-1) -- expand brackets
15=-4t+2 -- subtract 2
13=-4t -- switch signs, best to have a positive variable
4t=-13
t=-13/4
Answer:
1992.38
Step-by-step explanation:
The mean, or average, of a set of data points is found by adding all the values together and dividing by the number of values.
Sum:
1911.56 + 1956.69 + 1903.16 + 1958.82 + 1910.87 + 1983.14 + 2014.12 + 2023.86 + 2057.26 + 2034.21 + 2087.73 + 2067.14 = 23908.56
Divide:
There are 12 numbers, so divide 23908.56 by 12:
23908.56 / 12 = 1992.38
The average is thus 1992.38.

<span>There is an equation to solve this. It looks like:
Sum of interior angles = (n - 2) * 180 degrees
where n is the number of sides of the n-gon, which is 37.</span>
I think you either need to double 35 or use a protractor. Hope this is helpful!
