The median of the data set is 11.
Step-by-step explanation:
2, 2, 5, 10, 12, 13, 18, 24
10 + 12 = 22
22 / 2 = 11
step-by-step explanation:
no, her answer is not correct. we square the lengths of all sides and then determine whether the pythagorean theorem holds here:
9² + 15² = 306. this is not equal to the square of the longest side ( that square being 395. answer c is correct.
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.
