Answer:
72 I think
Step-by-step explanation:
I'm not 100% sure but I think its 72
The quadratic equation

can be written in the form:

Where p and q are the roots of the equation.
Given p = 4, q = -2, a = 3, the quadratic will look like this:

Finally, distribute and combine like terms to put it in standard form.
The interval

corresponds to the part of the distribution lying within 2 standard deviations of the mean (since 500-2*100=300 and 500+2*100=700). The empirical rule states that approximately 95% of the distribution is expected to fall in this range.
