Answer:
So the slope of this function is
and the y-intercept is 
Step-by-step explanation:
A first order function has the following format:

In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.
We have the following equation:

We just have to rewrite this equation



Which means that

So the slope of this function is
and the y-intercept is 
Answer:
B & C
Step-by-step explanation:
They are angles that are on the opposite side of the X, therefore having the same angle degree
Answer:
she will cover a distance of 0.85 km.
Step-by-step explanation:
We have,
Grace swam 0.6 kilometres during her first week of training and 0.25 kilometres during her second week of training.
It is required to find total distance covered by her in all.
It can be calculated simply adding the distance covered in first and second week of training. So,
Total distance, D = 0.6 km +0.25 km = 0.85 km
Hence, she will cover a distance of 0.85 km.
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>
1 chair = X
8 chairs = 8X
1 table = Y
8X - Y is the more amount you paid for chairs
