Answers
Scenario 1A:
Coinsurance amount is $90
Medicare payment is $360
Provider write-off is $290
Scenario 1B:
Remaining amount for Insurance and patient to pay is $350
Coinsurance amount is $70
Total paid by patient is $170
Medicare payment is $280
Provider write-off is $370
Scenario 1A:
Submitted charge: $650
Medicare participating physician fee schedule (PFS): $450
Coinsurance amount (20% paid by patient): $
Medicare payment (80% of the PFS): $
Provider write-off: $
To calculate the missing amounts, we can use the provided information:
Coinsurance amount (20% paid by patient):
Coinsurance amount = 20% of the Medicare participating physician fee schedule (PFS)
Coinsurance amount = 0.2 * $450 = $90
Medicare payment (80% of the PFS):
Medicare payment = 80% of the Medicare participating physician fee schedule (PFS)
Medicare payment = 0.8 * $450 = $360
Provider write-off:
Provider write-off = Submitted charge - Medicare payment
Provider write-off = $650 - $360 = $290
Scenario 1B:
Submitted charge: $650
Medicare participating physician fee schedule (PFS): $450
Patient pays $100 remaining on their deductible
Remaining amount for Insurance and patient to pay: $
Coinsurance amount (20% of remaining amount): $
Total paid by patient (deductible & 20% of remaining): $
Medicare payment (80% of the remaining amount): $
Provider write-off: $
To calculate the missing amounts, we can use the provided information:
Remaining amount for Insurance and patient to pay:
Remaining amount for Insurance and patient to pay = PFS - remaining deductible
Remaining amount for Insurance and patient to pay = $450 - $100 = $350
Coinsurance amount (20% of remaining amount):
Coinsurance amount = 20% of the remaining amount
Coinsurance amount = 0.2 * $350 = $70
Total paid by patient (deductible & 20% of remaining):
Total paid by patient = remaining deductible + coinsurance amount
Total paid by patient = $100 + $70 = $170
Medicare payment (80% of the remaining amount):
Medicare payment = 80% of the remaining amount

1 1 1 1 1 1 2 3 5 8 13 21 34 55 89 89 89 89 89 89. At what percentile is 34?
Answers
The value 34 is at the 55th percentile in the given dataset, meaning it is higher than 55% of the values and lower than 45% of the values.
To determine the percentile of 34 in the given dataset, we first need to arrange the values in ascending order: 1 1 1 1 1 1 2 3 5 8 13 21 34 55 89 89 89 89 89 89.
The percentile of a value represents the percentage of values in a dataset that are equal to or less than that value. In this case, there are 12 values that are less than or equal to 34. The total number of values in the dataset is 20.
To calculate the percentile, we use the formula:
Percentile = (Number of values less than or equal to the given value / Total number of values) × 100.
Therefore, the percentile of 34 is (12/20) × 100 = 60%. This means that 34 is higher than 60% of the values and lower than 40% of the values in the dataset.

You attend a wedding and are second in line to get a slice of wedding cake. there are 3 slices of vanilla cake, 12 slices of chocolate cake, and 6 slices of red velvet cake left. they are being handed out by a waiter at random. what is the probability that both you and the person in line in front of you get red velvet cake?
Answers
Answer:
1/14
Step-by-step explanation:
Let A represent the event First person getting red velvet cake
Let B represent the event Second person getting red velvet cake
P(A) = Total number of Red Velvet Cakes ÷ Total Number of Cakes =
6/21 = 2/7
If the first person gets a red velvet cake, then there are 5 red velvet cakes and 20 total cakes
Therefore P(B|A) = Number of red velvet cakes left ÷ total number of cakes left = 5/20 = 1/4
P(A and B) == probability of both getting red velvet cake P(A∩B) = P(A).P(B|A) = 2/7 × 1/4 = 2/28 = 1/14

coach Fitzpatrick has 12 basketballs in the storage bin at the beginning of practice he lives the basketballs up in the center core in rows of nine how many rows with nine basketballs will be lined up in the center court ?
Answers
The answer is that there will be one row with nine basketballs lined up in the center court, and the remaining three basketballs will not form a complete row.
To determine the number of rows with nine basketballs that will be lined up in the center court, we can divide the total number of basketballs by the number of basketballs in each row.
Given that Coach Fitzpatrick has 12 basketballs in the storage bin and he lines them up in rows of nine, we need to find how many times nine can be divided into 12.
Dividing 12 by 9, we get:
12 ÷ 9 = 1 remainder 3
This calculation tells us that we can have one full row of nine basketballs, and there will be three basketballs left over.
Since we are interested in the number of full rows, we can conclude that there will be one row with nine basketballs lined up in the center court.
The remaining three basketballs cannot form a complete row, so they will not be lined up in the center court. They may be placed separately or stored in another location.

c. $28,571.43
d. $30,000.00
e. None of the above
Answers
At year 2, you will have approximately $25,915.13 in your bank account, assuming an initial investment with a 5% interest rate compounded annually. The correct answer is (a).
To find out how much money you will have in your bank account at year 2, we can use the compound interest formula:
A = P(1 + r/n)^(nt)
Where:
A = Final amount (in this case, $30,000)
P = Principal amount (initial investment)
R = Annual interest rate (5% or 0.05)
N = Number of times interest is compounded per year (assumed to be once per year)
T = Number of years (in this case, 3)
Let’s solve for P, the principal amount at year 0:
30,000 = P(1 + 0.05/1)^(1*3)
30,000 = P(1.05)^3
Dividing both sides of the equation by (1.05)^3:
P = 30,000 / (1.05)^3
P ≈ 25,915.13
Therefore, at year 2, you will have approximately $25,915.13 in your bank account.
The correct answer is (a) $25,915.13.

There is a fixed cost of renting and variable cost per hour.
Let fixed cost be "x" and variable costs be "y".
Saturday Cost:
x + 3y = 435
Sunday Cost:
x + 5y = 625
To find x and y, we can solve the 2 equations simultaneously. Let's multiply first equation by "-1" and add up. Shown below:
\(\begin{gathered} -x-3y=-435 \\ x+5y=625 \\ ---------- \\ 2y=190 \\ y=\frac{190}{2} \\ y=95 \end{gathered}\)Putting this value of y into equation 2 [or equation 1 would be fine as well], we solve for x:
\(\begin{gathered} x+5y=625 \\ x+5(95)=625 \\ x+475=625 \\ x=625-475 \\ x=150 \end{gathered}\)So,
fixed cost = 150 dollars
variable cost (per hour cost) = 95 dollars
Now,
Monday, he rented for 2 hours, so the cost would be:
Monday Cost:
fixed + variable (for 2 hrs)
150 + 2(95) = 340 dollars
Total Cost of Renting (for 3 days):
435 + 625 + 340 = $1400

3. the volume of a cylinder is 12,566.4 cm3 . the height of the cylinder is 8 cm. 4 points a) find the radius of the cylinder to the nearest tenth of a centimeter. b) find the area of the base of the cylinder to the nearest tenth of a centimeter. c) find the lateral area to the nearest tenth of a centimeter. d) find the surface area of the cylinder.
Answers
The radius, Volume, Lateral area, and surface area of the cylinder are 22.4 cm, 157.0,356.7 cm2, and 670.9 cm2 respectively.
A)
V = (pi)(r2)(h)
12566.4 = (3.14)(r2)(8)
r2 = 500.3
r = 22.4 cm
B)
The volume of the cylinder V = A·h, i.e. to find the volume you multiply area A of the base by height h.
Hence A = V / h. Or A = 12,566.4 / 8 = 157.05 (cm2); if we round it, will be 157,1 cm2. This is a special case when 157.0 also could be written as an answer.
C)
The lateral area of a right cylinder is the size of the cylinder's side surface. AL = 2πRh. To find the radius of the cylinder, we recall the formula for base area A = πR2.
From this formula R = √(A / π)
After putting the value of area and π = 3.14 and calculations
we get R = √( 157.05 / 3.14 = 7.07 (cm) or 7.1 cm.
Now for the lateral area, we have A = 2·3.14·7.1·8 = 356.7 cm2.
D)
The surface area is a sum of the lateral area and 2 sums of the base area.
Thus, A = 356.7 cm2 + 2 x 157.1 cm2 = 670.9 cm2.

Exact form: years since 2000 Decimal form (nearest tenth): years since 2000
Answers
In the given scenario, the formula for the number of vehicles (V) as a function of t, the number of years since 2000, can be represented using the general exponential form:
(a) \(\[ V(t) = 200 \times (1 + 0.035)^t \]\)
Similarly, the formula for the number of people (P) as a function of t can be expressed as:
(b) \(\[ P(t) = 281 \times (1 + 0.01)^t \]\)
To find the point at which there is, on average, one vehicle per person, we need to determine the time when the ratio of the number of vehicles to the number of people becomes 1:1. Mathematically, this can be represented as:
\(\[ \frac{V(t)}{P(t)} = 1 \]\)
Substituting the formulas for V(t) and P(t) into the equation and solving for t:
\(\[ \frac{200 \times (1 + 0.035)^t}{281 \times (1 + 0.01)^t} = 1 \]\)
Taking the natural logarithm (ln) of both sides, we can simplify the equation to solve for t:
\(\[ t \times \ln(1 + 0.035) - t \times \ln(1 + 0.01) = \ln\left(\frac{281}{200}\right) \]\)
By evaluating this equation, we can determine the exact value of t, representing the years since 2000 when, on average, there is one vehicle per person. Additionally, we can calculate the decimal approximation of t, rounded to the nearest tenth, to provide a more practical representation of the time frame.
