We're not given the choices but we don't need them.
The only way this problem is tractable to a middle or high schooler is if the polynomial is perfect cube; a little thought yields
To find the inverse let's call f(x) x and call x y and solve for y.
Part A:
The poisson distribution is given by
Thus, given that <span>the mean number of hurricanes in a certain area is 7.2 per year.
The </span><span>probability that, in a year, there will be 6 hurricanes is given by
</span>
Part B:
<span>In a 45-year period, the number of years that are expected to have 6 hurricanes is given by 0.1445 x 45 = 6.5 years.
Part C:
The poisson distribution worked here because, the observed value of the number of years that hurricanes occurred in a 45 year period which is 6 is very close to the calculated value which is 6.5</span>

Answer:
Evidentially, make the photo smaller.
Step-by-step explanation:
It's because dividing 7/8 makes it a smaller number, which will obviously make the photograph smaller.
= 0.875
≈ 0.89
