Answer:
$20,783
Step-by-step explanation:
The original value of the car is given as $36,601.
Now, the residual value of the car after a 3 - year lease is given as $15,818.
Residual value is the amount that the person leasing this car can purchase it after the 3 years lease is expired.
Formula for his residual value is usually;
Residual value = original value - depreciation value
Where depreciation value is the amount of the cars original value the Person getting the vehicle on lease for 3 years would pay to cover that period.
Thus;
Depreciation value = 36601 - 15818 = $20783

A cylinder has been cut out of a solid. Find the volume of the remaining solid. Round answer to the nearest tenth.
Answer:
98.19
Step-by-step explanation:
Volume of whole cube minus volume of cylinder. volume of cylinder is pi x r^2 x h
The volume of remaining solid is 46.44 in³
What is Volume?Volume is the measure of the capacity that an object holds.
For example, if a cup can hold 100 ml of water up to the brim, its volume is said to be 100 ml. Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains. The best way to visualize volume is to think of it in terms of the space.
How To Calculate the Volume?Here are the steps to calculate volume of any solid shape:
Identify all the given parameters that are useful and are required to substitute in the respective volume formula. Such as the radius to be 'r' and height to be 'h', the slant height, diameter, etc.Make sure all the parameters are of the same units.Substitute the values in the volume formula of the respective shapes.Write the units as cubic units.edge= 6
Volume of cube= l³
= 6*6*6
=216 in³
Now, Volume of cylinder
=πr²h
= 3.14 * 3 * 3 * 6
=169.56 in³
Volume of remaining solid= 216- 169.56

find the nth maclaurin polynomial for the function. f(x) = sin(x), n = 3
P3(x) = ___
The third-degree Maclaurin polynomial for f(x) = sin(x) is P3(x) = x - (x^3) / 6.
To find the nth Maclaurin polynomial for the function f(x) = sin(x) when n = 3, we need to compute the polynomial up to the third-degree term.
The Maclaurin polynomial for a function f(x) centered at x = 0 is given by the formula:
Pn(x) = f(0) + f'(0)x + (f''(0)x^2) / 2! + (f'''(0)x^3) / 3! + ...
Let's calculate the nth Maclaurin polynomial for f(x) = sin(x) when n = 3:
First, we find the values of the function and its derivatives at x = 0:
f(0) = sin(0) = 0
f'(x) = cos(x), so f'(0) = cos(0) = 1
f''(x) = -sin(x), so f''(0) = -sin(0) = 0
f'''(x) = -cos(x), so f'''(0) = -cos(0) = -1
Using these values, we can write the Maclaurin polynomial:
P3(x) = 0 + 1x + (0x^2) / 2! + (-1x^3) / 3!
Simplifying further, we have:
P3(x) = x - (x^3) / 6.
Therefore, the third-degree Maclaurin polynomial for f(x) = sin(x) is:
P3(x) = x - (x^3) / 6.

approximate the sum of the series correct to four decimal places. [infinity] (−1)n − 1n2 8n n = 1
To approximate the sum of the series [infinity] (−1)n−1n^2/(8n), we can use a numerical method such as the partial sum method.
Let's calculate the partial sums of the series and add up terms until the sum converges to a desired level of accuracy. We will stop adding terms once the absolute difference between two consecutive partial sums is less than the desired accuracy.
Let's start by calculating the partial sums:
S_1 = (-1)^1-1(1^2)/(81) = 1/8
S_2 = (-1)^2-1(1^2)/(82) + (-1)^1-1(2^2)/(82) = 1/8 - 1/16 = 1/16
S_3 = (-1)^3-1(1^2)/(83) + (-1)^2-1(2^2)/(83) + (-1)^1-1(3^2)/(83) = 1/8 - 1/16 - 1/24 = -1/24
We can observe that the partial sums alternate between positive and negative values. This indicates that the series does not converge to a specific value but oscillates between two values.
To approximate the sum, we will calculate partial sums until the difference between two consecutive partial sums is less than the desired accuracy. Let's say we want the accuracy to be 0.0001.
Let's continue calculating partial sums:
S_4 = (-1)^4-1(1^2)/(84) + (-1)^3-1(2^2)/(84) + (-1)^2-1(3^2)/(84) + (-1)^1-1(4^2)/(84) = 1/8 - 1/16 - 1/24 + 1/32 = -1/48
S_5 = (-1)^5-1(1^2)/(85) + (-1)^4-1(2^2)/(85) + (-1)^3-1(3^2)/(85) + (-1)^2-1(4^2)/(85) + (-1)^1-1(5^2)/(8*5) = 1/8 - 1/16 - 1/24 + 1/32 + 1/40 = 1/120
The difference between S_4 and S_5 is 1/120 - (-1/48) = 1/120 + 1/48 = 1/80, which is greater than 0.0001.
Therefore, we can approximate the sum of the series as -1/48, correct to four decimal places.

y = x+2
z = y+2 = x+4
and
xyz = x³ + y² + 2z² substitiute x terms in for y and z
x(x+2)(x+4) = x³ + (x+2)² + 2(x+4)² solve for x by graphing on DEMOS
x = -2, 6 solved algebraically below
x = -2 y=0 z=2
x = 6 y=8 z=10
Checked both answers
xyz = x³ + y² + 2z²
-2(0)2 = -8 + 0 + 8 when x = -2
0 = 0
and
6(8)(10) = 6³ + 8² +2(10)² when x = 6
480 = 216+64+200
= 480
x(x+2)(x+4) = x³ + (x+2)² + 2(x+4)² solved algebraically
(x²+2x)(x+4) = x³ + x² +4x +4 + 2x² + 16x + 32
x³ + 6x² + 8x = x³ + x² +4x +4 + 2x² + 16x + 32
x³ + 6x² + 8x = x³ + 3x² + 20x + 36

A coach uses a new technique to train gymnasts. 7 gymnasts were randomly selected and their competition scores were recorded before and after the training. The results means of two populations are shown below. Assume that two dependent samples have been randomly selected from normally distributed populations. Using a 0.01 level of significance, test the claim that the training technique is effective in raising the gymnast scores?
before 9.5, 9.4, 9.6, 9.5, 9.5, 9.6, 9.7
after 9.6, 9.6, 9.6, 9.4, 9.6, 9.9, 9.5
There is insufficient evidence to support the claim that the training technique is effective in raising the gymnasts scores.
In hypothesis testing, we often use significance levels such as 0.01 to determine whether or not there is enough evidence to support the hypothesis.
Here is the solution to the given problem.
The null hypothesis is that the training technique is not effective in raising the gymnasts' scores.
It is expressed as
H0: µd = 0.
The alternative hypothesis is that the technique is effective in raising the gymnasts' scores.
It is expressed as
Ha: µd > 0.
The significance level α = 0.01 is given.
Therefore, the given problem can be tested using a one-tailed t-test.
This is because the alternative hypothesis states that the mean difference between the two populations is greater than zero.
A t-test is appropriate because the sample sizes are less than 30.
The difference between the before and after competition scores of each gymnast should be calculated.
This gives us the difference scores, which are as follows:
0.1, 0.2, -0.02, -0.1, 0.1, 0.3, -0.2.
Next, we compute the mean and standard deviation of the differences. We have:
n = 7d
= 0.0714Sd
= 0.1466
Then we compute the t-statistic:
t = (d - µd) / (Sd / √n)
t = (0.0714 - 0) / (0.1466 / √7)
t = 1.5184
The degrees of freedom for this test are (n - 1) = 6.
Using a t-distribution table with 6 degrees of freedom and a significance level of 0.01 for a one-tailed test, we find that the critical t-value is 2.998.
For the given problem, the test statistic t = 1.5184 is less than the critical value of 2.998.
Therefore, we do not reject the null hypothesis.
There is insufficient evidence to support the claim that the training technique is effective in raising the gymnast scores.

Answer:
53.8 gallons
Step-by-step explanation:
5.4*3=16.2
5.4 (gallons used per shower) * 3 (number of showers) = 16.2 (gallons used in 3 showers)
70-16.2=53.8
70 (Water in tank) - 16.2 (gallons used in 3 showers) = 53.8 (gallons of water left)
Hope this helps! Please brainliest!!!
Answer:
A(3) = 53.8 gallons left after 3 showers
Step-by-step explanation:
A(x) = volume of water left in tank = 70 gallons - (5.4 gallons)x, where x is the number of showers already taken.
After 3 showers, the volume of water left is A(3) = 70 gal - (5.4 gallons)(3), or

Michael wants to know if support for a local referendum on gay rights is related to political party affiliation. He conducts a survey of 200 local residents and asks them their political party affiliation and whether they intend to vote for or against the referendum. He learns that 16 people who say they are republican are for the referendum and 54 are against. Of those who say they are democrat, 72 people are for the referendum and 28 are against it. Some people identified as "other" and among that group, 3 were against the referendum and 27 were in favor of it. How would you represent the data in a table? Identify the null and alternative hypothesis. Conduct the appropriate analysis with a=.05. What should Michael conclude?
The answer is the test statistic (13.765) is greater than the critical value (5.991), we reject the null hypothesis. Therefore, we can conclude that there is a significant relationship between political party affiliation and support for the referendum on gay rights.
To represent the data in a table, we can create a contingency table:
For Against
Republican 16 54
Democrat 72 28
Other 27 3
Null hypothesis (H₀): There is no relationship between political party affiliation and support for the referendum on gay rights.
Alternative hypothesis (H₁): There is a relationship between political party affiliation and support for the referendum on gay rights.
To analyze the data, we can perform a chi-square test of independence. This test will determine if there is a significant association between political party affiliation and support for the referendum.
Applying the chi-square test at a significance level (α) of 0.05, we can calculate the test statistic and compare it to the critical value from the chi-square distribution with (rows - 1) × (columns - 1) degrees of freedom.
Let's calculate the expected frequencies for each cell assuming the null hypothesis is true:
For Against Total
Republican 27 43 70
Democrat 48 52 100
Other 12 18 30
Total 87 113 200
Now, we can calculate the chi-square statistic:
χ² = Σ[(O - E)² / E]
where O is the observed frequency and E is the expected frequency.
Performing the calculations, we find:
χ² ≈ 13.765
To determine the critical value, we need to find the degrees of freedom, which is equal to (rows - 1) × (columns - 1) = (3 - 1) × (2 - 1) = 2.
Using a chi-square distribution table or a statistical software, we find that the critical value for a significance level of 0.05 and 2 degrees of freedom is approximately 5.991.
Since the test statistic (13.765) is greater than the critical value (5.991), we reject the null hypothesis. Therefore, we can conclude that there is a significant relationship between political party affiliation and support for the referendum on gay rights.
In Michael's survey data, political party affiliation is related to the support for the referendum. Further analysis and interpretation of the results are needed to understand the nature and strength of this relationship.

In a particular region, 6% of the population is thought to have a certain disease. A standard diagnostic test has been found to correctly identify 91% of the people who have the disease. However, the test also incorrectly diagnoses 8% of those who do not have the disease as having the disease (in other words, the person does not have the disease but the test tells them that they do). A randomly selected person in the region is tested for the disease. (a) What is the probability the test comes back positive
Answer:
The positive predictive value ≈ 30.012%
Step-by-step explanation:
(a) The given percentage of the people in the region that have the disease, P(D) = 6% = 0.06
The percentage people correctly identified as having the disease by the standard diagnostic test = 91%
The percentage of people incorrectly identified as having the disease by the standard diagnostic test, P(T + |H) = 8%
Therefore, the sensitivity of the test, P(T + |D) = 0.91
The specificity of the test, P(T - |H) = 1 - 0.08 = 0.92
Therefore, the probability that a person is healthy, P(H) = 1 - 0.06 = 0.94
Therefore, in a population of 1,000 people, 60 people have the disease, with a sensitivity of 91%, the test will correctly pic 0.91×66 = 60.06 people correctly with the disease and 0.91 × 940 = 855.4 people without the disease
The number of non-diseased that test positive by the test is 0.08 × 1000 = 80 people which are false positives
Therefore, the number of diseased diagnosed as negative is 0.08 × 60 = 4.8
Therefore, we have;
[tex]\begin{array}{cccc}&Deseased&Non-diseased& Diseased + Non-diseased\\Test \ +ve&60.06&80& 140.06\\Test \ -ve&4.8&855.4&\end{array}[/tex]
The positive predictive value = Diseased +ve/(Diseased +ve + Non-diseased +ve)
[tex]The \ positive \ predictive \ value = \dfrac{Diseased +ve}{Diseased +ve + Non-diseased +ve} \times 100[/tex]
Therefore;
The positive predictive value = 60.06/(60.06 + 140.06) × 100 ≈ 30.012%
