Answer:
B)
Step-by-step explanation:
options B and C are the only equations that create a 'sideways' parabola
only option B would open to the right because the coefficient of the y-term is positive
X ÷ 3 = 10
what you want to do is isolate for x by multiplying both sides by 3
10 × 3 = 30
So x = 30
the mean is 50.5, but rounded it's 51.
