Answer:
Mean= 554.4
Standard deviation= 82
Step by step Explanation:
The question want us to calculate a) mean b) standard deviation, while we were given the probability mass function of random variables.
The percentage were of the carbon dioxide were given below;
6% of the trees in a minimal growth condition at 340 = 0.06
13% at 430 ppm = 0.13
46% at 560 ppm = 0.46
35% at 630 ppm= 0.35

The sum of exterior angles of ANY regular polygon is 360.
For example, the exterior angle of a square is 90 degrees time 4 vertices = 360 degrees.
The exterior angles of an equilateral triangle is 180-60=120, times 3 vertices = 360.
...and so on.
So we can use this fact to calculate the exterior angle of a REGULAR decagon, which is therefore 360/10=36 degrees.
According to the diagram, this angle (36 degrees) is the complement of x, so x=90-36=54 degrees.
Next, the interior angle is just the supplement of the exterior angle, namely
y=180-36=144 degrees.

There are two expressions
Price of video games: 4(25) = $100
Sale tax: 0.06(100) = $6
Total: $100 + $6 = $106
