Kevin looked at the dates on a random sample of 15 pennies taken from a small jar of pennies. He made the graph shown below to display the data.

Kevin will take 1 penny from the jar at random. Based on the data in the graph, what is the probability that the date on the penny will be earlier than 1990?

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

noncoplanar points are points that do not lie on the same line.
