Easy, 100 x 3 is 300 pounds, 5 x 3 is 15, so 15 pounds. :)
<span>3 is 1.0 below the mean. That is 1.0 / 0.9, or 1.1111... standard deviations below the mean.
So look up z < -1.11 on your graphing calculator.
It should be around 0.1335 or 13.35%</span>
The function appears to be neither odd nor even
Are there any answer choices?
