We can adjust the data by adding 4 to everything before we calculate the statistics. Or we can calculate the statistics on the given data and just add 4 to everything at the end. We'll get the same answer either way.
Let's sort the seven data points: 5 5 5 7 7 9 10
Those add up to 48 so the mean is 48/7 = 6.9
The one in the middle is 7 so the median = 7
The mode is the most common one, mode = 5
The range is the difference between max and min, so range = 10 - 5 = 5
In the second week we add four to everything. Since that adds four to the min and max, the range doesn't change.
Answer: mean=10.9, median=11, mode=9, range=5
Write a situation that could be modeled with the expression below.

PEMDAS
you would do left to right and look for multiplication or division.
64/2= 31
31*16=512
Answer:
Markup, 42% profit
Step-by-step explanation:
(someone check this)
You didn't specify the periodic payment in your question. I will solve it assuming that payment is made monthly.
Amount owing by Tom = 70% of 139,000 = 0.7 x 139,000 = $97,300
Present Value of an annuity is given by PV = P(1 - (1 + r)^-n)/r; where P is the periodic (monthly) payment, r is the interest rate = 12%/12 = 1% = 0.01, n is the number of periods = 25 x 12 = 300 months.
97,300 = P(1 - (1 + 0.01)^-300)/0.01
P = 973/(1 - (1.01)^-300) = 973/(1 - 0.050534) = 1,024.79
Thus Tom pays $1,024.79 per month.
Interest due for the first month = 0.01 x 97,300 = $973
Therefore, the portion of the first payment that covers the interest is $973
