Independent because the ratio of the second cube is the same (1:6), and it isn't affected by the result of the first cube
Plug the 5 into the x in the equation 2x. it should be 2(5) which equals 10.
Area of a triangle: 1/2 of area*height
(4*4)/2
16/2 = 8
8 * 4, since there are 4 triangles. = 32
18 * 8 (for the square) = 144
144 - 32 = 112 inches squared.
The triangles aren't shaded, so you can subtract them from the area of the rectangle to get the shaded area. The answer is 112 inches squared.
To plot the graph of the data given, we have a lot of options, one common option to plot this kind of data is a column bar graph.
The picture attached show the column bar for the data given, assuming that the age was measured in years and the height was measured in feet.
Some resources that could help to plot data are excel, origin or qtiplot.
2000 + 1200 = 3200
