The iterative function that describes how your new car loses value over time is f(t)=0. 75t, where t is the number of years since you purchased the car. If you paid $25,000 for your car and you sell it after owning the car for 3 years, how much is the car worth?
t_3=$14,062. 50
t_3=$10,546. 88
t_3=$7,910. 15
t_3=$18,750
If you paid $25,000 for your car and you sell it after owning the car for 3 years, then the worth of the car is t₃=$7,910. 15 (option c).
To find the value of your car after owning it for 3 years, we need to evaluate the function at t=3. This means we need to substitute t=3 into the function and simplify the expression.
f(3) = 0.75(3) = 2.25
The output of the function when t=3 is 2.25. But what does this number mean? It represents the fraction of the original value of the car that remains after owning it for 3 years.
To find the actual value of the car, we need to multiply this fraction by the original value of the car, which is given as $25,000.
Value of car after 3 years = 2.25 x $25,000 = $56,250
Therefore, the value of the car after owning it for 3 years is $7,910.15. This is the option (C) in the given choices.

In a survey of 175 females ages 16 to 24 who have completed
high school during the past 12 months, 72% were enrolled in college. In
survey of 160 males ages 16 to 24 who have completed high school during the
past 12 months, 65% were enrolled in college. At a = 0. 01, can you reject
the claim that there is no difference in the proportion of college enrollees
between the two groups?
There is no significant difference in the proportion of college enrollees between females and males who have completed high school within the past 12 months.
To determine if the difference in proportions is statistically significant or if it could be due to chance.
We will conduct a hypothesis test. Our null hypothesis (H₀) is that there is no difference in the proportion of college enrollees between females and males. Our alternative hypothesis (H₁) is that there is a difference in the proportion of college enrollees between females and males.
We can use a two-sample z-test to test this hypothesis. The formula for the test statistic is:
z = (p₁ - p₂) / √(p'* (1 - p') * ((1 / n₁) + (1 / n₂)))
where p₁ and p₂ are the sample proportions, p' is the pooled proportion, n₁ and n₂ are the sample sizes.
Given, p₁ = 0.72, p₂ = 0.65, n₁ = 175, n₂ = 160
p' = (x₁ + x₂) / (n₁ + n₂)
x₁ = 126 (0.72 * 175) and x₂ = 104 (0.65 * 160).
p' = (126 + 104) / (175 + 160) = 0.684
By applying the above values we get,
z = (0.72 - 0.65) / √(0.684 * (1 - 0.684) * ((1 / 175) + (1 / 160))) ≈ 2.11
The critical value for a two-tailed test with alpha = 0.01 is approximately ±2.58. Since our calculated z-value (2.11) is less than the critical value, we fail to reject the null hypothesis. This means that there is not enough evidence to conclude that there is a significant difference in the proportion of college enrollees between females and males.
Therefore, there is no significant difference in the proportion of college enrollees between females and males who have completed high school within the past 12 months.

Answer:
Step-by-step explanation:
To solve the equation (T/12) + 5 = (T/3) + (T/4), we need to simplify the right-hand side of the equation by finding a common denominator for T/3 and T/4.
The least common multiple of 3 and 4 is 12, so we can rewrite T/3 and T/4 as (4T/12) and (3T/12), respectively. Substituting these expressions into the equation, we get:
(T/12) + 5 = (4T/12) + (3T/12)
Simplifying the right-hand side, we get:
(T/12) + 5 = (7T/12)
Subtracting (T/12) from both sides, we get:
5 = (6T/12)
Simplifying the right-hand side, we get:
5 = (T/2)
Multiplying both sides by 2, we get:
T = 10
Therefore, the solution to the equation is T = 10.

Answer:
A
Step-by-step explanation:
2.17 > 2.017
because
2.017 = 2 + 17/1000
while
2.17 = 2 + 17/100 = 2 + 170/1000
170/1000 is larger than 17/1000.
for that reason D is wrong, of course.
2.17 is NOT equal to 2.017. 17/1000 is NOT equal to 170/1000.
2.018 = 2 + 18/1000
2.17 = 2 + 17/100 = 2 + 170/1000
also 18/1000 is NOT larger than 170/1000.
2.16 = 2 + 16/100 = 2 + 160/1000
2.017 = 2 + 17/1000
17/1000 are NOT larger than 160/1000.

please
he interest he will pay if he takes 2 years to pay his parents back is $153.16. The total amount he will pay if he takes 2 years to pay his parents back is $2,341.12.
To calculate the interest Adam will pay, we need to use the simple interest formula:
Interest = Principal x Rate x Time
The principal is the amount borrowed, which is $2,187.96. The rate is 3.5% per year, or 0.035 in decimal form. The time is 2 years.
Interest = $2,187.96 x 0.035 x 2 = $153.16
Therefore, Adam will pay $153.16 in interest if he takes 2 years to pay his parents back.
To calculate the total amount he will pay, we need to add the interest to the principal:
Total amount = Principal + Interest
Total amount = $2,187.96 + $153.16 = $2,341.12
Therefore, Adam will pay a total of $2,341.12 if he takes 2 years to pay his parents back.

Determine the equation of the tangent plane to the surface z = y ln x at the point (1, 4, 0)
z = 4(x - 1) - ln (y - 4)
Therefore, the equation of the tangent plane to the surface z = y ln x at the point (1, 4, 0) is z = 4(x - 1) - ln (y - 4).
To determine the equation of the tangent plane to the surface z = y ln x at the point (1, 4, 0), we first need to find the partial derivatives of the surface with respect to x and y.
∂z/∂x = y/x
∂z/∂y = ln x
Then, we can use these partial derivatives along with the point (1, 4, 0) to find the equation of the tangent plane using the formula:
z - z0 = ∂z/∂x(x0, y0)(x - x0) + ∂z/∂y(x0, y0)(y - y0)
where (x0, y0, z0) is the given point.
Plugging in the values, we have:
z - 0 = (4/1)(x - 1) + ln 1(y - 4)
Simplifying:
z = 4(x - 1) - ln (y - 4)
Therefore, the equation of the tangent plane to the surface z = y ln x at the point (1, 4, 0) is z = 4(x - 1) - ln (y - 4).

An object has a mass of 4. 70g. Calculate the Density of the object volume is 2. 55L
The density of the object is 0.0018 g/mL.
To calculate the density of the object, we need to use the formula:
Density = Mass / Volume
Given that the mass of the object is 4.70g and the volume is 2.55L, we can substitute these values into the formula:
Density = 4.70g / 2.55L
We need to convert the units of mass and volume to a consistent unit. Let's convert the volume from liters to milliliters (1L = 1000mL):
Density = 4.70g / 2550mL
Now we can simplify by dividing both the numerator and denominator by 10:
Density = 0.47g / 255mL
Finally, we can express the answer in units of g/mL:
Density = 0.0018 g/mL

The standard deviation of the scores on a skill evaluation test is 320 points with a mean of 1434 points. if 338 tests are sampled, what is the probability that the mean of the sample would differ from the population mean by less than 43 points? round your answer to four decimal places.
The probability that the mean of the sample would differ from the population mean by less than 43 points is approximately 0.7597 or 0.7600 (rounded to four decimal places).
Given that the standard deviation of the scores on a skill evaluation test is 320 points with a mean of 1434 points. And we have a sample of size n = 338.
We need to find the probability that the mean of the sample would differ from the population mean by less than 43 points.
The standard error of the mean is given by:
SE = σ/√n
where σ is the population standard deviation and n is the sample size.
Substituting the given values, we get:
SE = 320/√338
SE ≈ 17.398
To find the probability, we need to standardize the sample mean using the standard error as follows:
Z = (X - μ) / SE
where X is the sample mean, μ is the population mean, and SE is the standard error of the mean.
Substituting the given values, we get:
Z = (1434 - 1434) / 17.398
Z = 0
Since the mean difference is 0, we can find the probability of a difference less than 43 points by finding the probability that Z lies between -43/17.398 and 43/17.398.
Using a standard normal distribution table or calculator, we find that this probability is approximately 0.7597.
Therefore, the probability that the mean of the sample would differ from the population mean by less than 43 points is approximately 0.7597 or 0.7600 (rounded to four decimal places).

the following list shows the number of goals scored by a soccer team in each of 9 games. 0 0 1 1 1 3 3 4 5 how does the median number of goals scored compare with the mean number of goals scored? responses
The median number of goals scored is 1, and the mean number of goals scored is 2. The median is less than the mean, indicating a right-skewed distribution.
To find the median, we need to first put the numbers in order
0, 0, 1, 1, 1, 3, 3, 4, 5
There are an odd number of values, so the median is the middle value, which is 1.
To find the mean, we add up all the values and divide by the number of values
(0 + 0 + 1 + 1 + 1 + 3 + 3 + 4 + 5) / 9 = 2
So the mean number of goals scored is 2.
Since the median (1) is less than the mean (2), we can say that the distribution is skewed to the right. This is because the high value of 5 pulls the mean up, while the median is not affected as much by outliers.

Solve the seperable differential equation 1 9yy' = 2. Use the following initial condition: y(9) = 7. = Express x? in terms of y. x2 = (function of y).
the solution to the differential equation is: x = (1/36) y² - (13/36) Note that this equation represents a parabolic curve in the (x,y)-plane, opening upwards and with its vertex at (-13/36,0).
We can start by separating the variables and integrating both sides of the equation:
1/9 y dy = 2 dx
Integrating both sides with respect to their respective variables, we get:
(1/18) y² = 2x + C
where C is the constant of integration.
Using the initial condition y(9) = 7, we can substitute x=9 and y=7 to solve for C:
(1/18) (7²) = 2(9) + C
C = 49/2 - 18 = 13/2
Substituting this value of C back into the general solution, we get:
(1/18) y² = 2x + 13/2
Simplifying and solving for x, we get:
x = (1/36) y² - (13/36)

How to find the possible rectangles?Let L be the length of the rectangular garden and W be the width of the garden. Since the garden is enclosed by four sides, Wes will need 2L+2W feet of fencing to enclose it. We know that he has 20 feet of fencing, so we have the equation:
2L + 2W = 20
We also know that the smallest side of the garden should be 3 feet or longer, so:
L >= 3
W >= 3
To find the possible rectangles Wes can make, we can solve the equation for one variable in terms of the other:
2L + 2W = 20
2L = 20 - 2W
L = 10 - W
Now we can substitute this expression for L into the inequality L >= 3 to get:
10 - W >= 3
W <= 7
Similarly, we can substitute L = 10 - W into the inequality W >= 3 to get:
10 - L >= 3
L <= 7
Therefore, the possible values for L and W are:
3 <= L <= 7
3 <= W <= 7
We can also use the equation 2L + 2W = 20 to find the combinations of L and W that add up to 10, since the total length of fencing is 20 feet:
L = 3, W = 7
L = 4, W = 6
L = 5, W = 5
L = 6, W = 4
L = 7, W = 3
These are the possible rectangles that Wes can make with his 20 feet of fencing, where the smallest side is 3 feet or longer.

If p : q = 2/3 : 2 and p : r = 3/4 : 1/2 , calculate the ratio p : q : r Giving your answer in its simplest form.
please help i mark it as brainly
If p : q = 2/3 : 2 and p : r = 3/4 : 1/2 , the ratio of p : q : r in its simplest form is 32 : 27 : 24.
To calculate the ratio p : q : r, we need to first find the values of p, q, and r. We can use the given proportions to set up a system of equations and solve for the variables.
From the first proportion, we know that:
p/q = 2/3 : 2
We can simplify this by cross-multiplying:
p = (2/3) * 2q
p = (4/3)q
From the second proportion, we know that:
p/r = 3/4 : 1/2
Again, we can cross-multiply and simplify:
p = (3/4) * r/(1/2)
p = (3/2)r
Now we have two equations for p in terms of q and r. We can substitute these into each other and solve for q and r:
(4/3)q = (3/2)r
r/q = (8/9)
q/r = (9/8)
Now we have the ratios of r to q and q to r. We can use these to find the ratio of p, q, and r:
p : q : r = p : q * (9/8) : r * (8/9)
Substituting the values we found for p in terms of q and r:
p : q : r = (4/3)q : q * (9/8) : r * (8/9)
Simplifying:
p : q : r = 32 : 27 : 24

Based on the percentage of daily of total daily calories and the number of calories needed how many biscuits packages of pemmican and packages of butter and cocoa does one person need each day?
To determine how many biscuit packages, pemmican packages, and butter and cocoa packages are needed per day for one person.
What factors are necessary for daily food requirements?
Calculating an individual's daily Caloric food requirements based on calorie intake and percentage of calories from each food group requires several pieces of information. The first is the total daily calorie requirement, which varies based on factors such as age, gender, height, weight, and physical activity level.
The second is the percentage of daily calories that should come from each food group, which is determined by dietary guidelines and varies based on factors such as age and gender. Finally, the calorie content of each food item must be known to determine how much of each food is needed to meet daily calorie and nutrient requirements.
Once these factors are known, it is possible to calculate how many biscuit packages, pemmican packages, and butter and cocoa packages are needed per day for one person. However, without knowing the specific calorie content and nutritional value of each food item, it is impossible to provide a specific answer.

Which recursive formula defines the sequence of f(1)=6, f(4)=12, f(7)=18
The recursive formula for this sequence is f(n) = f(n-3) + 6n - 18.
How did get the formula?We can use the method of finite differences to find a possible recursive formula for this sequence.
First, let's compute the first few differences:
f(4) - f(1) = 6
f(7) - f(4) = 6
Since the second differences are zero, we can assume that the sequence is a quadratic sequence. Let's write it in the form f(n) = an^2 + bn + c. We can solve for the coefficients using the given values:
f(1) = a(1)^2 + b(1) + c = 6
f(4) = a(4)^2 + b(4) + c = 12
f(7) = a(7)^2 + b(7) + c = 18
Solving for a, b, and c, we get:
a = 1
b = 5
c = 0
Therefore, the recursive formula for this sequence is f(n) = f(n-3) + 6n - 18.

Factor out the GCF.
6x²-3x - 18
Factor completely and show/explain each step.
Answer:
3(x - 2)(2x + 3)
Step-by-step explanation:
6x² - 3x - 18 ← factor out GCF of 3 from each term
= 3(2x² - x - 6) ← factor the quadratic
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 6 = - 12 and sum = - 1
the factors are - 4 and + 3
use these factors to split the x- term
2x² - 4x + 3x - 6 ( factor the first/second and third/fourth terms )
= 2x(x - 2) + 3(x - 2) ← factor out (x - 2) from each term
= (x - 2)(2x + 3) ← in factored form
then
6x² - 3x - 18 = 3(x - 2)(2x + 3)

James says the fraction 3/4 has the same value as the expression 4 ÷ 3. I disagree with James' statement.
The fraction 3/4 is not the same as the expression 4 ÷ 3. A fraction can be interpreted as division of the numerator (top number) by the denominator (bottom number). In this case, 3/4 represents the division of 3 by 4, whereas 4 ÷ 3 represents the division of 4 by 3. These two expressions have different values and are not equal.

Find the absolute extrema if they exist, as well as all values of where they occur, for the function f(x) = 8+x/2-x on the domain [-2, 0]
Find the derivative of f(x) = 8+x/2-x
f'(x) = ...
The absolute maximum is f(-2) = 10/3, and absolute minimum is f(0) = 8.
How to determined the absolute extrema?First, let's find the derivative of the function:
f(x) = 8+x/2-x
f'(x) = (1/2) - 1 = -1/2
Next, we need to find the critical points of the function on the given domain.
In this case, the derivative is always defined and is never zero. Therefore, there are no critical points on the given domain.
Next, we check the endpoints of the domain, x = -2 and x = 0:
f(-2) = 8 + (-2)/(2-(-2)) = 10/3
f(0) = 8 + 0/(2-0) = 8
Since the function is continuous on the closed interval [-2, 0],
The extreme value theorem tells us that the function must have both an absolute maximum and an absolute minimum on the interval.
Therefore, the absolute maximum occurs at x = -2 and is f(-2) = 10/3, and the absolute minimum occurs at x = 0 and is f(0) = 8.
