Please help on this math question!!

Answer:

x = 49

Step-by-step explanation:

The third side of the largest of the inner triangles:

= \sqrt{(7\sqrt{(33)^{2} }- (33)^{2}

=\sqrt{528} =\sqrt{(16)(33)} =4\sqrt{33}

The side that continues next to 33: x -33

Applying similarity property on right triangles:

\frac{33}{4\sqrt{33} } =\frac{4\sqrt{33} }{x-33}

(33)(x-33)=(4\sqrt{33} )^{2}

33x-1089=528

33x=528+1089

x=\frac{528+1089}{33} =49

Hope this helps

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.
