A sample of 50 11th graders were asked to select a favorite pattern out of 6 choices. The data list below shows what their favor

ite color patterns were, and the accompanying frequency table and bar graph represent these 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 percentages, from 0 percent up to 30 percent. What will be the height of the green bar?

A.
15

B.
25

C.
9

D.

Answer:

D 18

Step-by-step explanation:

100% = 50 (all students)

1% = 100%/100 = 50/100 = 1/2 = 0.5

we get any percentage for any number by dividing the number by 1% (0.5) to see how often it fits in.

there are 9 votes for green.

9/ 0.5 = 18%

A toxic radioactive substance with a density of 9 milligrams per square centimeter is detected in the ventilating ducts of a nuc
Crank

  Think about what a half-life means as a table.

years amount Left

20 1/2

40 1/4

60 1/8

80 1/16

Starting at t = 0, the amount left (or density) = (1/2)^(t/20)

For t =35, the decay factor = .297

Since you need to work backwards, divide by that factor.  6 / .297 = 20.18 mg per sq cm

Triangles equal 180. The bottom left corner is 90 in this triangle. Add the angles together set equal to 180.

x = unknown angle

90 + 67 + x= 180
157 + x= 180
subtract 157 from both sides
x= 23

ANSWER: x=23

Hope this helps! :)

kolbaska11 [484]

Answer: the velocity and position vector is given by;

v(t) = 3i + 2j + (1-32t)k

r(t) = (3t)i + (5-2t)j + (2+t-16t^2)k

The position at time t=2; r(2)

r(2) = 6i + j - 60k

Step-by-step explanation:
