Answer:
$563.24
Step-by-step explanation:
The monthly payment on a mortgage loan is found using the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where A is the monthly payment on a loan of P at interest rate r for t years.
Filling in the given values, we find the payment to be ...
A = $70,000×(0.09/12)/(1 -(1 +0.09/12)^(-12·30)) ≈ $563.236
The monthly payment is about $563.24.

Many graphing calculators and all spreadsheets have functions that will do this calculation for you.
Answer:
p value = 0.3122
Step-by-step explanation:
Given that Pedro thinks that he has a special relationship with the number 3. In particular,
Normally for a die to show 3, probability p = 
Or proportion p = 0.1667
Pedro claims that this probability is more than 0.1667

where P is the sample proportion.
b) n=30 and 
Mean difference = 
Std error for proportion = 
Test statistic Z = p difference/std error = 0.4894
p value = 0.3122
p >0.05
So not significant difference between the two proportions.
The first one is quadratic function
I think its... A (but not sure)
Please see the pic, I'd solved in it.
