Theoretically, each letter should have the same probability of occurring since there are 15 of each. There are 5 letters that can be drawn, so there is a total of 75 balls, and each letter has a probability 
of being drawn.
This means one would expect a theoretical frequency of 
, i.e. any given letter should get drawn 250 times, which means the answer is D.
Answer:
Slope = rise / run
= -12 / 1500 (It's -12 and not 12 because a drop means it's decreasing)
= -0.008
Answer:
No options
Step-by-step explanation:
Knowing that V=in/min = x(t)/t and according to the graph,
V=20in/20min=in/min, so
No options since speed is not inches per minute, spedd (V) = inches over minutes
The change in the water level should decrease by 1.2 inches in 24 hours.
If you would like to divide 2 by 1 6/7, you can do this using the following steps:
1 6/7 = 13/7
2 / 1 6/7 = 2 / 13/7 = 2/1 / 13/7 = 2/1 * 7/13 = 14/13 = 1 1/13
The correct result would be 1 1/13.
