You have a balance of 17,426 on your credit card. Your minimum monthly payment is 461 . If your interest rate is 15.5%, how many years will it take to pay off your card assuming you don't add any debt? Enter your response to two decimal places (ex: 1.23)
With a credit card balance of $17,426, a minimum monthly payment of $461, and an interest rate of 15.5%, we need to calculate the number of years it will take to pay off the card without adding any additional debt.
To determine the time required to pay off the credit card, we consider the monthly payment and the interest rate. Each month, a portion of the payment goes towards reducing the balance, while the remaining balance accrues interest.
To calculate the time needed for repayment, we track the decreasing balance each month. First, we determine the interest accrued on the remaining balance by multiplying it by the monthly interest rate (15.5% divided by 12).
We continue making monthly payments until the remaining balance reaches zero. By dividing the initial balance by the monthly payment minus the portion allocated to interest, we obtain the number of months needed for repayment. Finally, we divide the result by 12 to convert it into years.
In this scenario, it will take approximately 3.81 years to pay off the credit card (17,426 / (461 - (17,426 * (15.5% / 12))) / 12).

Dan used 1 3/8 gallons of gas on Saturday and 4 1/3 gallons on Sunday how many gallons did he use on the two days combined? Write your answer as a mixed number In simplest form
Dan used a total of 5 17/24 gallons of gas on Saturday and Sunday combined.
How to estimate the total gallons of gas Dan used on Saturday and Sunday combined?To find the total number of gallons Dan used on Saturday and Sunday, we shall add the amount of gas he used each day.
On Saturday, Dan used 1 3/8 gallons.
On Sunday, Dan used 4 1/3 gallons.
To add these two amounts, we shall find a common denominator by determining the least common multiple (LCM) of 8 and 3 is 24.
Converting 1 3/8 to an improper fraction:
1 3/8 = (8 * 1 + 3) / 8 = 11/8
Converting 4 1/3 to an improper fraction:
4 1/3 = (3 * 4 + 1) / 3 = 13/3
Now we can add the fractions using a common denominator, which is 24 in this case:
Let's convert both fractions:
11/8 = (11 * 3) / (8 * 3) = 33/24
13/3 = (13 * 8) / (3 * 8) = 104/24
Now we can add the fractions:
33/24 + 104/24 = (33 + 104) / 24 = 137/24
So, simplifying the fraction, we have:
137/24 = 5 (remainder 17)
5 17/24 gallons.
Hence, Dan used a total of 5 17/24 gallons of gas on Saturday and Sunday combined.

In Milgram's first study of obedience, the majority of teachers initially complied but refused to deliver more than slight levels of shock.
In Milgram's first study of obedience, participants were assigned the role of 'teacher' and were instructed to administer electric shocks to a 'learner' whenever they answered a question incorrectly. The shocks ranged from mild to severe, with the highest level labeled as 'XXX.' The learner was actually an actor, and no real shocks were administered.
The study found that the majority of teachers initially complied with the experimenter's orders and delivered shocks, but they refused to deliver more than slight levels of shock. This suggests that while they were willing to follow the instructions to some extent, they had moral reservations about causing significant harm to another person.
It is important to note that the study has been criticized for ethical concerns and the potential psychological harm it may have caused to participants. However, it remains a significant contribution to our understanding of obedience and the power of authority figures.

the degenerative disease osteoarthritis most frequently affects weight-bearing joints such as the knee. an article presented the following summary data on stance duration (ms) for samples of both older and younger adults. age n sample mean sample sd older 28 801 117 younger 16 780 72 assume that both stance duration distributions are normal. a) calculate and interpret a 99% confidence interval (ci) for true average stance duration among elderly individuals. b) carry out a test of hypotheses to decide whether true average stance duration is larger among elderly individuals than among younger individuals. c) construct a 95% ci for the difference in means and compare results to part(b).
We are 99% confident that the true average stance duration among elderly individuals lies within the range of 744.56 ms to 857.44 ms.
To test whether the true average stance duration is larger among elderly individuals than among younger individuals, we can perform a one-tailed independent samples t-test. The null hypothesis (H0)
Using the t-test, we compare the means and standard deviations of the two samples and calculate the test statistic
a) To calculate a 99% confidence interval for the true average stance duration among elderly individuals, we can use the sample mean, sample standard deviation, and the t-distribution.
Given:
Older adults: n = 28, sample mean = 801, sample standard deviation = 117
Using the formula for a confidence interval for the mean, we have:
Margin of error = t * (sample standard deviation / √n)
Since the sample size is relatively large (n > 30), we can use the z-score instead of the t-score for a 99% confidence interval. The critical z-value for a 99% confidence level is approximately 2.576.
Calculating the margin of error:
Margin of error = 2.576 * (117 / √28) ≈ 56.44
The confidence interval is then calculated as:
Confidence interval = (sample mean - margin of error, sample mean + margin of error)
Confidence interval = (801 - 56.44, 801 + 56.44) ≈ (744.56, 857.44)
b) To test whether the true average stance duration is larger among elderly individuals than among younger individuals, we can perform a one-tailed independent samples t-test.
The null hypothesis (H0): The true average stance duration among elderly individuals is equal to or less than the true average stance duration among younger individuals.
The alternative hypothesis (Ha): The true average stance duration among elderly individuals is larger than the true average stance duration among younger individuals.
. With the given data, perform the t-test and obtain the p-value.
c) To construct a 95% confidence interval for the difference in means between older and younger adults, we can use the formula for the confidence interval of the difference in means.
Given:
Older adults: n1 = 28, sample mean1 = 801, sample standard deviation1 = 117
Younger adults: n2 = 16, sample mean2 = 780, sample standard deviation2 = 72
Calculating the standard error of the difference in means:
Standard error = √((s1^2 / n1) + (s2^2 / n2))
Standard error = √((117^2 / 28) + (72^2 / 16)) ≈ 33.89
Using the t-distribution and a 95% confidence level, the critical t-value (with degrees of freedom = n1 + n2 - 2) is approximately 2.048.
Calculating the margin of error:
Margin of error = t * standard error
Margin of error = 2.048 * 33.89 ≈ 69.29
The confidence interval is then calculated as:
Confidence interval = (mean1 - mean2 - margin of error, mean1 - mean2 + margin of error)
Confidence interval = (801 - 780 - 69.29, 801 - 780 + 69.29) ≈ (-48.29, 38.29)
Comparison with part (b): In part (b), we performed a one-tailed test to determine if the true average stance duration among elderly individuals is larger than among younger individuals. In part (c), the 95% confidence interval for the difference in means (-48.29, 38.29) includes zero. This suggests that we do not have sufficient evidence to conclude that the true average stance duration is significantly larger among elderly individuals compared to younger individuals at the 95% confidence level.

water is leaking out of an inverted conical tank at a rate of 8 , 900 8,900 cubic centimeters per min at the same time that water is being pumped into the tank at a constant rate. the tank has height 11 11 meters and the diameter at the top is 5.5 5.5 meters. if the water level is rising at a rate of 24 24 centimeters per minute when the height of the water is 3 3 meters, find the rate at which water is being pumped into the tank in cubic centimeters per minute.
the rate at which water is being pumped into the tank in cubic centimeters per minute. is 1508527.582 cm³/min
The net rate of flow dV/dt = flow rate in - flow rate out
Let flow rate in = k. Since flow rate out = 8900 cm³/min,
dV/dt = k - 8900
Now, the volume of a cone V = πr²h/3 where r = radius of cone and h = height of cone
dV/dt = d(πr²h/3)/dt = (πr²dh/dt)/3 + 2πrhdr/dt (since dr/dt is not given we assume it is zero)
So, dV/dt = (πr²dh/dt)/3
Let h = height of tank = 11 m, r = radius of tank = diameter/2 = 3/2 = 1.5 m, h' = height when water level is rising at a rate of 21 cm/min = 3.5 m and r' = radius when water level is rising at a rate of 21 cm/min
Now, by similar triangles, h/r = h'/r'
r' = h'r/h = 3.5 m × 1.5 m/12 m = 5.25 m²/12 m = 2.625 m = 262.5 cm
Since the rate at which the water level is rising is dh/dt = 21 cm/min, and the radius at that point is r' = 262.5 cm.
The net rate of increase of water is dV/dt = (πr'²dh/dt)/3
dV/dt = (π(262.5 cm)² × 21 cm/min)/3
dV/dt = (π(68906.25 cm²) × 21 cm/min)/3
dV/dt = 1447031.25π/3 cm³
dV/dt = 4545982.745/3 cm³
dV/dt = 1515327.582 cm³/min
Since dV/dt = k - 6800 cm³/min
k = dV/dt - 6800 cm³/min
k = 1515327.582 cm³/min - 6800 cm³/min
k = 1508527.582 cm³/min
So, the rate at which water is pumped in is 1508527.582 cm³/min

A cylindrical tank whose diameter is 1.4 metres and height 80 cm is initially empty. Water whose volume is 492.8 litres is poured into the tank. Determine the fraction of the tank filled with water. (4 marks
Answer:
7/40 is the fraction filled with water
Step-by-step explanation:
Here we start by calculating the volume of the cylindrical tank.
Mathematically, that would be;
V = π * r^2 * h
From the question
r = 80 cm = 80/100 = 0.8 meters
h = 1.4 meters
π = 22/7
Plugging these values into the volume equation, we have;
V = 22/7 * 0.8 * 0.8 * 1.4 = 2.816 m^3
But mathematically;
1 m^3 = 1000 liters
So 2.816 m^3 = 2.816 * 1000 = 2816 liters
So the fraction filled with water will be;
492.8/2816 = 0.175 = 175/1000 = 7/40
