A jar contains black marbles and green
marbles. Sixty percent of the marbles in the jar
are green. A number generator simulates
randomly selecting 10 marbles from the jar.
The number generator is used 12 times and
the number of green marbles in each trial is
shown in the dot plot.
Which description is correct about the number
generator being fair or not?
A. The number generator is not fair. In most of the experiments, considerably less than 60% of the selected marbles are green.
B. The number generator is fair. It shows 60% of the marbles selected are green most of the time.
C. The number generator is not fair. The dot plot shows 80% of the marbles drawn are green.
D. The number generator is fair. The dot plot shows a distribution that is skewed right.

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
