A sample of 50 11th graders were asked to select a favorite pattern out of six choices. The data list below shows what their fav

orite color patterns were, and the accompanying frequency table and bar graph represent this data. In the bar graph, the height of the blue-gray bar is 4, the height of the green bar is 9, and so on. Suppose that, rather than being just a bar graph, the display you see above is a relative frequency bar graph. The vertical axis of the graph will be marked off in percents, from 0 percent up to 30 percent. What will be the height of the yellow bar?

P = 10/171

P = 0.058

What is the volume of the composite figure shown below?
AVprozaik [17]

Answer:

2412 mm³

Step-by-step explanation:

In the figure attached, the composite figure is shown.

Dimension of top rectangular prism:

  • length of 13 millimeters
  • width of 12 millimeters
  • height of 12 millimeters

Volume of top rectangular prism: length*width*height = 13*12*12 = 1872 mm³

Dimension of bottom rectangular prism:

  • length of 15 millimeters
  • width of 12 millimeters
  • height of 3 millimeters

Volume of bottom rectangular prism: length*width*height = 15*12*3 = 540 mm³

Volume of the composite figure: 1872 + 540 = 2412 mm³

If y = 3x - 4 and the domain is {-3,-1,4}, find the range.
GREYUIT [131]
We could put the domain into the x values to get the y values (range). 

y = 3(-3) - 4
y = -9 - 4
y = -13

y = 3(-1) - 4
y = -3 - 4
y = -7

y = 3(4) - 4
y = 12 - 4
y = 8
