The mean absolute deviation of a set of data is the average distance between each data value and the mean. The mean number of contacts stored and the distance each data value is from the mean is shown below. Each data value is represented by an ×. So, the mean absolute deviation is 3.75<span>.

Hi there
We know that the formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value
PMT monthly payment
R interest rate
K compounded monthly 12 because the payment is monthly
N time
What we need from the formula above to find the monthly payment
So to find the monthly payment the formula
PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]
Another important things we need is how to find total payments and interest charge
To find total payments
Monthly payment×12
And to find interest charge
Total payments-present value
Now let's find interest charge for each credit card
Credit card A
The monthly payment is
PMT=563÷((1−(1+0.16÷12)^(
−12))÷(0.16÷12))=51.08
Total payments
51.08×12=612.96
interest charge
612.96−563=49.96
Credit card b
PMT=2,525÷((1−(1+0.21÷12)^(
−12))÷(0.21÷12))=235.11
Total payments
235.11×12=2,821.32
interest charge
2,821.32−2,525=296.32
Credit card c
PMT=972÷((1−(1+0.19÷12)^(
−12))÷(0.19÷12))=89.58
Total payments
89.58×12=1,074.96
interest charge
1,074.96−972=102.96
So total interest charge for all credit cards is
102.96+296.32+49.96
=449.24....final answer
It's c
Good luck!
Answer:
44, 45
Step-by-step explanation:
The number halfway between them is their average: 89/2 = 44.5. The two integers are 44 and 45.
Answer:
C- third option
Step-by-step explanation:
1. you would have to distribute the 1/3 to both x and 9
2. then cancel out the 6 from both sides to get your answer in slope-intercept form
Answer:
Constant of proportionality should be 48.
Step-by-step explanation:
Given that a small pie factory needs to ship 360 pies a day to stay profitable. 180 pies are baked every 3 hours. Of the baked pies, 20% go directly to freezer storage and 80% are loaded on a truck for delivery.
Now we need to find about what is the constant of proportionality for the number of pies baked and loaded on a truck for delivery.
Number of baked pies = 180
Number of pies loaded on truck for delivery = 80% of baked pies
= 0.80(180)= 144 in 3 hours.
So number of pies loaded per hour = 144/3= 48
Hence constant of proportionality should be 48.
