Dimas [21]
Combine the x terms:
11x-10=180
Add Both sides by 10:
11x=190
Divide both sides by 11:
X=190/11

Name all of the angles in these polygones (info in picture) FAST!!
Klio2033 [76]

First of all this is a very poor question, and you should question it a bit. What are these figures? Are they regular? (first 2). Is the last one a parallelogram. I'm going to assume that the yellow one is a rectangle and the middle one is a pentagon and the last one is a parallelogram.

Yellow

A has 4 right angles (That's the property of a rectangle).

Green

B has 5 angles that are equal to 108 degrees. If you draw a 2 lines from any vertex you get 3 triangles. The size of the interior angles totals 3 triangles * 180 degrees = 540 degrees.

540/3 = 108.

Each angle in the interior is 108 degrees.

B has 5 angles all equal 108 degrees. All 5 are obtuse.

Red

Just by sight and assumption C has 2 obtuse angles, and 2 acute angles.

Consider a nine -year moving average used to smooth a time series that was first recorded in 1961. a. Which year serves as the f
kirill [66]

Answer:

  a.  1965

  b.  8 years

Step-by-step explanation:

For answers to questions like these it can work to consider the smallest possible dataset.

<h3>Dataset</h3>

For our purpose, consider the 9 years/values to be averaged to be ...

  1, 2, 3, 4, 5, 6, 7, 8 ,9

<h3>Observations</h3>

a. The center value of the data set is 5. Its number is 5-1=4 more than the first one.

The first centered value is from the year 1961 +4 = 1965.

b. The 4 values at the beginning, and the 4 values at the end do not have a corresponding "average" value. That is, 4+4 = 8 values in the series are lost with respect to the number of average values.

8 years of values are lost.
