Peter is interested in designing an experiment to test the probability of tossing a certain number on a fair cube. He will toss one cube 10 times in a row and count how many times the cube lands on the number 6. What is one aspect of this experiment he can change to make the results even more accurate? A. He can toss more than one cube.
B. He can use a number other than 6 to count.
C. He can toss the cube more than 10 times.
D. He can time the experiment.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

step-by-step explanation:

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
