Answer:
Step-by-step explanation:
Quadratic function is given as 
Let's find a, b and c:
Substituting (0, 6):
Now that we know the value of c, let's derive 2 system of equations we would use to solve for a and b simultaneously as follows.
Substituting (2, 16), and c = 6
=> (Equation 1)
Substituting (3, 33), and c = 6
=> (Equation 2)
Subtract equation 1 from equation 2 to solve simultaneously for a and b.
Replace a with 4 in equation 2.
The quadratic function that represents the given 3 points would be as follows:
Answer:
D. The McCarter's must make more than 10 visits to the pool for the pass to be a better deal.
Step-by-step explanation:
First, I chose the option that seemed most likely. Once I chose D, I plugged in the answer to see if it actually worked.
10 x 7.5 =75 dollars + 50 (pass fee) = 125 dollars total.
10 x 12.5= 125 dollars.
Therefore, in order to get a deal off of the seasonal pass, the McCarter's would have to visit the pool more than 10 times. D.
898 mm because 8.98 is a lot smaller, it's only in the ones place.
Given that the mean is $9.5 and the standard deviation is $1.30, the standard error will be given by:
σ/√n
where
σ-standard deviation
n=sample size
thus, we shal have:
1.30/√20
=0.2906
Next we find the margin error
0.2906*2=0.581
thus the confidence interval will be:
(9.5+0.581, 9.5-0.581)
=(10.081,8.919)
Simply put, its a LONGER way to do division. You take a longer time on showing the work.
