Statistical questions are questions that are answered by collecting variable data, which can be given as an average/range/percentage. This question has a single answer, and therefore it is not a statistical question. A statistical question would be, for example, What is the average amount of time students in this class spend playing musical instruments?
Answer:
The new mortgage repayment is $10,580.69
Step-by-step explanation:
As at the time Douglas lost his job,he has already made repayments on the mortgage for a period of 7 years,by extending the repayment period by another 7 years,Douglas now have a period of repayment of 30 years now(30-7+7).
The new repayment yearly can be computed using the pmt formula in excel as given below:
=pmt(rate,nper,-pv,fv)
rate is the interest rate on mortgage given as 4.25%
nper is the period of repayment now 30 years
pv is the current of balance of $177,533.62
fv is the total amount repayable on the mortgage and it is not known hence taken as zero
=pmt(4.25%,30,-177533.62,0)=$10,580.69
1. First step: To get a term of x by itself, add 5 to both sides
Second step: This will become 3x<24
Third step: To separate 3x, divide everything by 3: 3x÷3 < 24÷3
Step four: x < 8
2. First subtract both sides by 12: - 2x + 12 - 12 < - 4 - 12
Second: This becomes - 2x < -16
Third: Divide by -2 to get x by itself - 2x ÷ - 2 > -16 ÷ - 2 Note: If you divide by a negative number, the inequality sign switches. This is a really important step that most students forget.
Fourth: x>8
Note: Try plugging in values when you are done if you are uncertain you have the right answer.
The period of a sinusoid

is

, so any range such that

will give two complete periods.
