Answer:
$6.83
Step-by-step explanation:
To start off, we would want to graph the points.
Once we have our graph, we see our correlation is positive, meaning that every year past 1950, the price of 1 movie ticket increases.
Our next step would to figure out the linear regression, or to guess a best line of fit. Once we do so, we should see where the movie tickets should <em>approxametly </em>rise to.
We then use the best line of fit to estimate the price in 2015, or when x = 65 (65 years after 1950).
The answer closest to the estimate would be 6.83. Attached image is the graph on Desmos.

Answer:
<h2>y + 3 = 2(x + 3)</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
![y-y_1=m(x+x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x%2Bx_1%29)
<em>m</em><em> - slope</em>
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
From the graph we have the points (-3, -3) and (0, 3).
Calculate the slope:
![m=\dfrac{3-(-3)}{0-(-3)}=\dfrac{6}{3}=2](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B3-%28-3%29%7D%7B0-%28-3%29%7D%3D%5Cdfrac%7B6%7D%7B3%7D%3D2)
Put the value of the slope and the coordinates of the point (-3, -3) to the equation of a line:
![y-(-3)=2(x-(-3))\\\\y+3=2(x+3)](https://tex.z-dn.net/?f=y-%28-3%29%3D2%28x-%28-3%29%29%5C%5C%5C%5Cy%2B3%3D2%28x%2B3%29)
![y=2x+3](https://tex.z-dn.net/?f=y%3D2x%2B3)

If 5m is the radius, then multiply it by 2, then multiply it by
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
.
If 5m is the diameter, then just multiply it by only

Answer:
50 Degrees
Step-by-step explanation:
Since they already have 40 degrees for you, and a little square means a right angle (90 Degrees), then 40 + 90 is 130. The interior angles of a triangle always add up to 180, so 180 - 130 is 50. The answer is therefore 50 degrees.
