Find MA:
MA = 67.2-32 = 35.2
Now set up a ratio:
35.2/67.2 = x/81.9
Cross multiply:
67.2x = 2882.88
Divide both sides by 67.2:
X = 42.9
I'm assuming that you meant h = 6 for choice B, in which case that would be correct.
Answer:
the median will be 200.
the mode will be 402 n 398.
the mean will be 400.
4x - 12
You can get this by switch the f(x) and the x and then solving for the new f(x)
