Answer:
Step-by-step explanation:
First, we need to calculate the annual interest rate from the given APR.
APR = 2.25%
Daily interest rate = 2.25% / 365 = 0.00616438
Now, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the final amount
P = the principal (initial amount)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = time in years
In this case, P = $2,000, r = 0.00616438, n = 365 (daily compounding), and t = 4.
A = 2000(1 + 0.00616438/365)^(365*4)
A = 2000(1.00616438)^1460
A = $2,388.34 (rounded to the nearest cent)
Therefore, the answer is option D) $2,388.34.
the contingency table shows the results of a survey of students in two math classes. find p(more than 1 hour of tv | 6th period class). round to the nearest thousandth. did you watch more than one hour of tv last night?
The probability of P(more than 1 hour of TV | 6th period class) is option (D) 0.765
To find P(more than 1 hour of TV | 6th period class), we need to use conditional probability formula
P(more than 1 hour of TV | 6th period class) = P(more than 1 hour of TV and 6th period class) / P(6th period class)
The number of students who watched more than 1 hour of TV and were in the 6th period class is 13. Therefore, P(more than 1 hour of TV and 6th period class) = 13 / (13 + 10) = 13/23.
The total number of students in the 6th period class is 13 + 10 = 23. Therefore, P(6th period class) = 23 / (6 + 23) = 23/29.
Putting it all together
P(more than 1 hour of TV | 6th period class) = P(more than 1 hour of TV and 6th period class) / P(6th period class) = (13/23) / (23/29) = 0.765 (rounded to the nearest thousandth)
Therefore, the correct option is (D) 0.765

Dylan has $20.00 on his gift card. After some purchases, he has $0.06 remaining on his gift card. Dylan has _____% of the original amount remaining on the gift card.
Answer:
Step-by-step explanation:
To find the percentage of the original amount that Dylan has remaining on his gift card, we can divide the remaining amount by the original amount and then multiply by 100 to express it as a percentage.
The original amount on the gift card was $20.00, and the remaining amount is $0.06, so the percentage of the original amount that Dylan has remaining on his gift card is:
($0.06 ÷ $20.00) x 100% =
0.003 x 100% =
0.3%
Therefore, Dylan has 0.3% of the original amount remaining on his gift card.

if n is the product of all multiples of 3 between 1 and 100, what is the greatest integer m for which is an integer?
The greatest integer m for which n is an integer is 40.
This is because the product of all multiples of 3 between 1 and 100 (n) is equal to the product of all integers from 3 to 99, which is equal to 3^39*2^20.
By using the prime factorization of n, we can see that the greatest integer m is equal to the sum of the exponents of the prime factors, which is 39 + 20 = 40.
To solve this problem, we must first factor n, which is the product of all multiples of 3 between 1 and 100. n can be expressed as a product of prime factors 3^39*2^20.
This can be further expressed as 3^39*2^20 = (3*2)^39*2^20 = 6^39*2^20. To find the greatest integer m for which n is an integer, we must add the exponents of the prime factors, which gives us 39 + 20 = 40. Therefore, the greatest integer m for which n is an integer is 40.

You need 1.8 lbs of the type of chocolate that sells for $2.50/lb and 6.6 lbs of the type of chocolate that sells for $3.60/lb.
A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and visual solutions are possible for these problems. The intersection of two lines represents the system of equations' solution.
let
x = lbs of the type of chocolate that sells for $2.50/lb
y = lbs of the another type of chocolate that sells for $3.90/lb
You would like to have 8.4 lbs of a chocolate mixture that sells for $3.60/lb
x + y = 8.4
2.50x + 3.90y = 8.4 x 3.60
2.50x + 3.90y = 30.24
Putting the value of x = 8.4 - y in equation 2.
2.50( 8.4 - y) + 3.90y = 30.24
21 - 2.5y + 3.9 y = 30.24

what is the probability that a randomly selected gas station in russia charged more than the mean price in the united state
The probability that a randomly selected gas station in Russia charges more than the mean price in the United States is quite low.
This is because the prices of gas in Russia are typically much lower than the mean price of gas in the United States. The average cost of gasoline in Russia is around $0.50 per liter while in the United States, the average price of gas is around $1.78 per liter.
To explain further, the cost of living in Russia is lower than the cost of living in the United States. This means that there is more disposable income for people living in Russia and as a result, the price of gas is much lower than in the United States.
In addition, the cost of transportation and other production costs are lower in Russia than in the United States, which also keeps the prices of gas in Russia lower.
All of these factors make it unlikely that a randomly selected gas station in Russia would be charging more than the mean price in the United States.

Frequency table:
A frequency table is a statistical tool that is used to organize raw data in a clear and concise manner.
It is a way of representing the information contained in the data so that it can be easily interpreted and analyzed.
A frequency table is often used to summarize categorical data, such as the data collected in a marketing study like the one mentioned in the question.
The marketing study in this question involved asking 100 consumers to select the best digital music player from three options:
the iPod Touch, Sony Walkman, and Zune HD.
To create a frequency table from this data, we would need to count the number of times each option was chosen by the consumers.
This can be done by grouping the data into classes, which are categories that are created based on the values in the data.
For this particular study, there are only three options to choose from, so there are only three possible classes:
iPod Touch, Sony Walkman, and Zune HD. We would simply count the number of times each option was chosen and record it in the appropriate class.
The resulting frequency table would look something like this: Digital Music Player Frequency i Pod Touch 45 Sony Walkman 28 Zune HD27

consider a situation in which we calculate a 95% confidence interval that ranges from 35 to 45. if we conducted a two-sided test with the null hypothesis of the population mean equaling 43, what would the likely result of our test be?
The result of the two-sided test with the null hypothesis of the population mean equaling 43, based on the 95% confidence interval that ranges from 35 to 45, would be rejecting the null hypothesis.
The 95% confidence interval that ranges from 35 to 45 suggests that we are 95% confident that the true population mean falls between those values.
To conduct a two-sided test with the null hypothesis of the population mean equaling 43, we can use the confidence interval to see if the null hypothesis falls within the range of the confidence interval or not.
Since the null hypothesis of 43 is not within the confidence interval of 35 to 45, we can reject the null hypothesis at the 0.05 level of significance, which means we have evidence to suggest that the true population mean is not 43.
Therefore, the likely result of our test would be rejecting the null hypothesis.

?
To answer this problem, we must utilize the information provided to calculate the number of round trips Spencer takes every week. Spencer commutes a total of 16 miles each week,
which translates to 8 miles to work and 8 miles home. We also know that he lives around a quarter mile from his employment. the number of round trips Spencer takes every week. Spencer commutes a total of 16 miles each week, Thus we can create an equation to calculate the number of round trips he takes 8 = (4/5) * n where n is the number of trips Spencer takes. To find n, we can cross-multiply: 8 * 5 = 4 * n n = 20/4 n = 5 As a result,Spencer lives 4/5 mile. In one week, he commutes a total of 16 miles to and from work.
