Answer:

Step-by-step explanation:
If the figures are similar, then the angles are the same. So that means that angle H is equal to angle D (you can count he little arcs in the angle to find it's matching partner). Since this is true:

Which is the same as
. Solve for x by dividing both sides by 4:

Finito.
Answer:
2045
Step-by-step explanation:
-34×12(-5)+5
-405(-5)+5
2040+5
2045 is the answer
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>
