A hat contains four balls. The balls are numbered 2, 4, 4, and 5. One ball is randomly selected and not replaced, and then a second ball is selected. The numbers on the two balls are added together.

A fair decision is to be made about which of three sizes of ice cream cone will be ordered, using the sum of the numbers on the balls. The sizes are small, medium and large.

Which description accurately explains how a fair decision can be made in this situation?

If the sum is 6, a small cone will be ordered.
If the sum is 7 or 8, a medium cone will be ordered.
If the sum is 9, a large cone will be ordered.

If the sum is 6 or 7, a small cone will be ordered.
If the sum is 8, a medium cone will be ordered.
If the sum is 9, a large cone will be ordered.

If the sum is 6, a small cone will be ordered.
If the sum is 7 or 9, a medium cone will be ordered.
If the sum is 8, a large cone will be ordered.

If the sum is 6 or 9, a small cone will be ordered.
If the sum is 7, a medium cone will be ordered.
If the sum is 8, a large cone will be ordered.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
