183560 is your answer when you add it
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.
5.22 dollars is what I got any body do anything different
Answer:
Step-by-step explanation:
in this specific case the two legs are congruent:
b = 18
For the Pythagorean theorem
a = √ 2 * 18^2 = 18√2
