Question 1
Find the unpaid balance, new interest, and purchasing power on the credit card after the minimum monthly payment is made. The interest charge for unpaid balances is 18% per year.
Credit Card Balance = $5000
Credit Limit = $5000
Minimum Payment = $125.00
After making the minimum payment of $125, the unpaid balance on the credit card is $4875, the new interest charge is $75, and the purchasing power is $50.
How to find the purchasing power?If the minimum monthly payment of $125 is made, we can calculate the new balance, unpaid balance, and interest charge as follows:
The interest rate per month is (18% per year) / 12 = 1.5% per month.
First, we calculate the interest charge for the month on the unpaid balance:
Interest charge = (1.5% per month) x ($5000 unpaid balance)
Interest charge = $75
Next, we subtract the minimum payment from the unpaid balance to get the new unpaid balance:
Unpaid balance = $5000 - $125
Unpaid balance= $4875
Then, we add the interest charge to the new unpaid balance to get the new balance:
New balance = $4875 + $75
New balance = $4950
Finally, we can calculate the purchasing power as the credit limit minus the new balance:
Purchasing power = $5000 - $4950
Purchasing power = $50
Therefore the unpaid balance on the credit card is $4875, the new interest charge is $75, and the purchasing power is $50.

Suppose that buses are scheduled to arrive at a bus stop at noon but they are always X minutes late, where X is an exponential random variable with a mean of 4 minutes. Suppose that you arrived at the bus stop precisely at noon, and have been waiting for 10 minutes. Compute the probability that you have to wait an additional six minutes or more.
On solving the provided question, we can say that Given that you have already waited for 10 minutes, the inequality that you will have to wait another six minutes or longer is around 0.0183.
What is inequality?A connection between two expressions or values that is not equal is known as an inequality in mathematics. Inequality follows imbalance, therefore. In mathematics, an inequality makes a connection between two values that are not equal. Egality and inequality are different. The not equal symbol is often used to indicate that two values are not equal (). Various inequalities are employed to contrast values of all sizes. By changing the two sides until just the variables are left, one may solve many straightforward inequalities. However a variety of factors support inequality: Negative values are split or added on either side. Switch between the left and right.
Applying the exponential distribution's memoryless characteristic, we have:
P(Y ≥ 6 | Y > 10) = P(Y ≥ 16)
= 1 - P(Y < 16)
= 1 - F(16) (16)
where F(t) is the exponential distribution's cumulative distribution function (CDF) with a mean of 4 minutes.
F(t) = 1 - e(-t/) yields the CDF of an exponential distribution with mean, where t 0. As a result, we have:
[tex]P(Y \geq 6 | Y > 10) = 1 - F(16) (16)\\= 1 - (1 - e^(-16/4))\\= e^(-4) (-4)\\≈ 0.0183[/tex]
Given that you have already waited for 10 minutes, the likelihood that you will have to wait another six minutes or longer is around 0.0183.

In the United States, 41% of 18 to 29-year-olds said in a survey held in March 2020 that they turrently subscribed to Hulu. What is the probability in a random sample of 55 18 to 29-year-olds that 20 will say they currently have a subscription to Hulu?
The probability in a random sample of 55 18 to 29-year-olds that 20 will say they currently have a subscription to Hulu is: 0.087.
How to find the probability?This is a binomial distribution problem, where n = 55 and the probability of success (i.e. a person subscribing to Hulu) is p = 0.41.
The probability mass function of a binomial distribution is:
P(X = x) = (nCx) * p^x * (1-p)^(n-x)
where nCx is the binomial coefficient (i.e. the number of ways to choose x items from n items).
So, in this case, we want to find P(X = 20):
P(X = 20) = (55C20) * 0.41^20 * (1-0.41)^(55-20)
P(X = 20) ≈ 0.087
Therefore, the probability that in a random sample of 55 18 to 29-year-olds, 20 will say they currently have a subscription to Hulu is approximately 0.087or 8.7%.

A $40,000 car depreciates in value at a rate of 36% per year. The
value, V, after t years can be modeled by the function V =
40,000(0.64). Which function is equivalent to the original function?
. V = 40,000(0.8)St
V=40,000(0.8)2t
V = 40,000(0.8)
V = 40,000(0.8)
The correct function equivalent to the original function V = 40,000(0.64) is V = 40,000(0.64)ⁿ.
What is percent?Percent is a way of expressing a fraction or a decimal as a fraction of 100. It is denoted by the symbol "%". For example, the fraction 3/4 can be written as 75% and the decimal 0.5 can be written as 50%. Percentages are commonly used in everyday life to express values such as discounts, interest rates, and success rates.
Here,
The original function V = 40,000(0.64) models the value, V, of a $40,000 car after t years, where the car depreciates at a rate of 36% per year. The expression 0.64 represents the remaining value of the car after one year, which is obtained by subtracting 36% from 100% (i.e., 100% - 36% = 64%).
To find an equivalent function, we need to simplify 0.64. We can write 0.64 as 0.8², since 0.8 multiplied by itself gives 0.64.
So, V = 40,000(0.64) is equivalent to V = 40,000(0.8²), which simplifies to V = 40,000(0.64). This means that both expressions represent the same function that models the value of the car after t years, given that the car depreciates at a rate of 36% per year.

An automobile company is running a new television commercial in five cities with approximately the same population. The following table shows the number of times the commercial is run on TV in each city and the number of car sales (in hundreds). Find the Pearson correlation coefficient r for the data given in the table. Round any intermediate calculations to no less than six decimal places, and round your final answer to three decimal places.
Therefore , the solution of the given problem of data plot comes out to be value (r) is roughly 0.975.
Data plot: What is it?The most typical way to display data in a graph is to demonstrate how two additional factors relate to one another. Digital and hand-drawn sketches are both acceptable. From the beginning position, move two or more pieces to the correct and three pieces up. The reference system must display the numerals for positions 2, 3, and 4. In your points, be very clear. The pinkish haze with the letter P stands in for the number 2.3.
Here,
We must compute several numbers in order to determine the Pearson correlation coefficient r for the information provided in the table.
Before anything else, we figure out the average and standard deviation of the amount of TV airings (x) and car sales (y):
mean(x) = (40 + 30 + 20 + 50 + 10) / 5 = 30
mean(y) = (30 + 20 + 10 + 40 + 20) / 5 = 24
These mean numbers allow us to determine the standard deviation:
=> SX = √ (( (40-30)² + (30-30)² + (20-30)² + (50-30)² + (10-30)²) / 4)
≈> 15.81
=> SY = √(( (30-24)²+ (20-24)² + (10-24)² + (40-24)² + (20-24)²) / 4)
≈> 8.16
Next, we determine x and y's covariance:
=> cov(x,y) =
=> [(40-30)(30-24) + (30-30)(20-24) + (20-30)(10-24) + (50-30)(40-24) + (10-30)(20-24)] / 4
≈> 125
Last but not least, we can figure out the Pearson association coefficient:
0.975 r = cov(x,y) / (s x * s y)
As a result, the table's data's Pearson correlation value (r) is roughly 0.975. This shows a significant positive correlation between the volume of car purchases and the frequency of the TV ad.

Jamie bought a shirt and a jacket for a total price of $164. The cost of the jacket was $17 more than twice the price of the shirt
The price οf the jacket was $115.
Let's start by defining sοme variables tο represent the unknοwn quantities:
Let x be the price οf the shirt
Let y be the price οf the jacket
Frοm the prοblem statement, we knοw that:
y = 2x + 17 (the cοst οf the jacket was $17 mοre than twice the price οf the shirt)
x + y = 164 (the tοtal cοst οf the shirt and jacket was $164)
We can use these twο equatiοns tο sοlve fοr the values οf x and y. One way tο dο this is tο substitute the expressiοn fοr y frοm the first equatiοn intο the secοnd equatiοn, and then sοlve fοr x:
x + (2x + 17) = 164
3x + 17 = 164
3x = 147

Alice walks along a road which can be modeled by the equation y=4x, where (0,0) represents her starting point. When she reaches a certain point A, she turns right, so that she is traveling perpendicular to the original road, until she stops at the point (85,0).
Therefore , the solution of the given problem of equation comes out to be spot A's coordinates are (80,-20).
Equation: What is it?In mathematical formulas, it is common to use the same variable term to guarantee agreement between two claims. Mathematical assertions, also known as equations expression, are employed to convey the equality of numerous academic figures. In this case, the normalise method adds b + 6 using the data of y + 6 rather than splitting 12 into two parts.
Here,
Let (a,b) represent the location of point A. Consequently, the inclination of the line through (0,0) and (a,b) is
=> m = (b - 0) / (a - 0) Equals b / a
This line being parallel to the initial road gives us:
=> m = -1/4
Therefore:
=> b / a = -1/4
=> b = -a/4
=> √[(a - 0)² + (-a/4 - 0)²] = √(17a²/16)
From (a,-a/4) to (85,0), the distance is:
=> √[(85 - a)² + (0 - (-a/4))²] = √[(85 - a)² + (a/4)²]
These two separations are equal, so we can put them at the same value and find a:
=> √[(85 - a)² + (a/4)²] = √(17a²/16)
When we square both edges, we obtain:
=> (85 - a)² + (a/4)² = 17a²/16
=> 16(85 - a)² + a² = 17a²
=> 16(7225 - 170a + a²) + a² = 17a²
=> 115600 - 2720a + 17a² + a² = 17a²
=> 18a² - 2720a + 115600 = 0
=> 9a² - 1360a + 57800 = 0
=> a = (1360 ± √(1360² - 4957800)) / (2*9)
=> a = (1360 ± √(307600)) / 18
=> a = (1360 ± 560) / 18
=> a = 80 or a = 40/9
Point A's y-coordinate is:
=> b = -a/4 = -80/4 = -20
Consequently, spot A's coordinates are (80,-20).

What is the standard error σM for this sample? (rounded to the nearest tenth: e.g. 2.2)
To calculate the standard error σM for a sample, we can use the formula [tex]σM = s / \sqrt{n}[/tex], where s: sample standard deviation and n: sample size.
The formula for calculating the standard error, M, which indicates the standard deviation of the sampling distribution of the mean, is as follows:
[tex]σM = σ / \sqrt{n}[/tex]
where σ: population standard deviation and n: sample size.
If we don't know the population standard deviation, we estimate it using the sample standard deviation s. We use formula:
[tex]σM = s / \sqrt{n}[/tex]
We can apply the method above with the sample size n and the sample standard deviation s if we are given a sample and asked to determine the standard error M for this sample.
By adding up each value in the sample and dividing by the sample size, we can determine the sample mean x, from which we may compute the sample standard deviation. The sample variance is then determined by adding up the squared deviations between each value and the sample mean, then dividing the result by the sample size less one. Lastly, we calculate the sample standard deviation by taking the square root of the sample variance.
Once we have calculated the sample standard deviation s and the sample size n, we can plug these values into the formula for σM:
[tex]σM = s / \sqrt{n}[/tex]
and calculate standard error.
In conclusion, the formula M = s / [tex]\sqrt{n}[/tex]n, where s: sample standard deviation and n: sample size, can be used to compute the standard error M for a sample.

An input of 6 is mapped to an output of 6.An input of 3 is mapped to an output of 8.An input of 9 is mapped to an output of 12.An input of 7 is mapped to an output of 8.Hence the x-value can only by 8 or 12, and we choose y = 8, while the y-value is free, hence we choose y = 7.

Find the slope between the following points:(-5,5),and (3,-12) *
m = (-12 - 5) / (3 - (-5))
m = (-17) / (3 + 5)
m = (-17) / 8
Therefore, the slope between the points (-5, 5) and (3, -12) is -17/8.
