Ajar 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

i would need to see the dot plot : )

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
