Answer:
B.1 1/4
Step-by-step explanation:
Answer:
B. Median is greater than the mean and the majority of data points are to the right of the mean.
Step-by-step explanation:
Mean = sum(x × p(x))
= (1×0.1)+(2×0.15)+(3×0.2)+(4×0.45)+(5×0.1)
= 3.3
Probability of more than 3.3 is:
0.45 + 0.1 = 0.55 > 0.5
It shows that a parabola can be described by tangents formed by lines with decreasing y-intercepts and equivalently increasing x-intercepts.
