(a) (10 points) if a person is chosen at random, the test is administered, and the person tests positive, what is the probability that this person has the disease? simplify your answe
Answers
The probability that a person has a disease given that they test positive, when 0.4% of the population has the disease and the test is positive with probability 0.99 if they have the disease and 0.03 if they don't have it, is 0.116 or about 11.6%.
Let D be the event that the person has the disease and T be the event that the person tests positive. We need to calculate P(D|T), the probability that the person has the disease given that they test positive.
Using Bayes' theorem, we have
P(D|T) = P(T|D) * P(D) / P(T)
where P(T|D) is the probability of testing positive given that the person has the disease, P(D) is the prior probability of having the disease, and P(T) is the total probability of testing positive, which can be calculated as
P(T) = P(T|D) * P(D) + P(T|D') * P(D')
where P(T|D') is the probability of testing positive given that the person does not have the disease, and P(D') is the complement of P(D), which is the probability of not having the disease.
Substituting the given values, we get
P(D|T) = (0.99 * 0.004) / [(0.99 * 0.004) + (0.03 * 0.996)]
= 0.116
Therefore, the probability that the person has the disease given that they test positive is 0.116 or about 11.6%.

A plumber has a 2.5 metre long copper wire. he needs to cut lengths of 60cm, 35cm and 90cm work out how much of the initial 2.5 metre long pipe is left. give your answer in cm
Answers
By the concept of measurement of length we get the remaining length of the pipe 65 cm.
The total length of pipe before it was used by the plumber was 2.5 metre = (2.5 x 100)cm = 250cm.
Since,the plumber needs to cut lengths of 60cm, 35cm and 90cm
Thus,total Length of the pipe cut by the plumber = 60cm + 35cm + 90cm = 185cm
After subtracting the length of pipe used by the plumber from the original length of the pipe, we get,
The remaining length of the pipe = 250 - 185 = 65cm
Hence, the remaining length of the pipe is 65 cm.

This question makes an important point: the maximum point of a function may not always be found by solving f'(x) = 0 Remember: functions can have their minimum or maximum at an endpoint of their domain, at a point of non-differentiability (think of the absolute value function, which has its minimum point at zero) or may not even have a maximum or minimum. This means that the most thorough way of solving optimization problems involves sketching the objective function. (For questions that appear on tests, however, the optimum will usually occur at a relative max. or relative min. that can be found by solving f'(x) = 0.) Two parts of this question are multiple choice: you only get one submission attempt for those two parts. A peach orchard owner wants to maximize the amount of peaches produced by his orchard. He has found that the per-tree yield is equal to 900 whenever he plants 30 or fewer trees per acre, and that when more than 30 trees are planted per acre, the per-tree yield decreases by 40 peaches per tree for every extra tree planted. For example, if there were 25 trees planted per acre, each tree would produce 900 peaches. If there were 35 trees planted per acre, each tree would produce 900 - 40 (35 - 30) peaches, which is roughly equal to 700 peaches. Find the function that describes the per-tree yield, Y, in terms of x. Y = if is no more than 30 trees per acre Y= Find the total yield per acre, T, that results from planting x trees per acre.

Answers
The maximum point of a function found by solving f'(x) = 0
1.Y(x) = 900, if x ≤ 30
2.900 - 40(x - 30), if x > 30
3.T(x) = x × Y(x)
4.dT/dx = 900, if x < 30
5.2100x - 40x² if x > 30
6.The derivative dT/dx equals zero at x = 52.5, but it is not valid in the given context.
7.The maximum yield occurs at x = 30 trees per acre, with a maximum yield of 27,000 peaches per acre.
8.T(x) is differentiable at x = 30.
To find the function that describes the per-tree yield, Y, in terms of x, use the given information:
If there are 30 or fewer trees planted per acre (x ≤ 30), the per-tree yield is 900 peaches per tree.
If there are more than 30 trees planted per acre (x > 30), the per-tree yield decreases by 40 peaches for every extra tree planted beyond 30.
The function Y(x) as follows:
Y(x) = 900, if x ≤ 30
Y(x) = 900 - 40(x - 30), if x > 30
find the total yield per acre, T, that results from planting x trees per acre. The total yield is simply the per-tree yield (Y) multiplied by the number of trees per acre (x):
T(x) = x × Y(x)
differentiate T with respect to x (dT/dx) to find where the maximum yield occurs.
dT/dx = d/dx (x × Y(x))
dT/dx = d/dx (x × (900 - 40(x - 30)))
To find if this derivative ever equals zero, it to zero and solve for x:
0 = 900 - 40(x - 30)
40(x - 30) = 900
x - 30 = 22.5
x = 52.5
So, the derivative dT/dx equals zero at x = 52.5. However, we need to check whether this value is valid for our function. Recall that if x > 30, the per-tree yield decreases by 40 peaches for every extra tree planted beyond 30. Therefore, planting 52.5 trees per acre would result in a negative per-tree yield, which is not physically meaningful in this context. Thus, the maximum yield occurs at the critical point within the valid domain, which is x = 30.
Now, let's find the maximum value of the yield at x = 30:
T(30) = 30 ×Y(30) = 30 × 900 = 27,000 peaches per acre
The optimal value of x that maximizes the yield is 30 trees per acre, and the maximum yield is 27,000 peaches per acre.
Finally, let's determine if T(x) is differentiable when x equals 30. Since T(x) is a piecewise function, we need to check if the left and right-hand derivatives at x = 30 are the same.
Left-hand derivative (x < 30):
dT/dx = d/dx (x × 900) = 900
Right-hand derivative (x > 30):
dT/dx = d/dx (x × (900 - 40(x - 30))) = d/dx (x × (900 - 40x + 1200)) = d/dx (2100x - 40x²)
Now, evaluate the right-hand derivative at x = 30:
dT/dx = 2100(30) - 40(30)² = 63,000 - 36,000 = 27,000
Since the left-hand derivative and the right-hand derivative at x = 30 are equal (both are 27,000), T(x) is differentiable at x = 30.

Answers
Answer:
Plots that can detect violations in regression assumptions, while response plots help analyse the relationship between the response variable and predictors are Residual plots and scatterplot matrix.
Step-by-step explanation:
There are several graphical plots commonly used to detect violations of regression model assumptions and analyze estimated regression models. Here are a few examples:
Residual plot: A residual plot shows the difference between the observed values of the response variable and the predicted values from the regression model. Patterns in the residuals, such as nonlinearity, heteroscedasticity (unequal variances), or outliers, can indicate violations of assumptions.
Response plot: This plot examines the relationship between the response variable and one of the predictor variables while holding other predictors constant. It helps identify nonlinearity or other issues in the relationship between the response and predictors.
Scatterplot matrix: A scatterplot matrix displays scatterplots between pairs of predictor variables. It can help detect issues like perfect multicollinearity, which occurs when two or more predictors are highly correlated, leading to problems in estimating the regression coefficients.

Answers
Answer:
Longer than
Step-by-step explanation:
The lengths of sides A C and F E are congruent. The lengths of sides B C and D E are congruent. Therefore:
AC = FE, BC = DE
Also m∠C is greater than m∠E
∠C is the angle opposite to line AB and ∠E is the angle opposite to line DF. Since AC = FE, BC = DE and m∠C is greater than m∠E. The length of a side of a shape is proportional to its opposite angle, since the opposite angle of AB is greater than the opposite angle of DF therefore AB is greater than DF
From the given two triangles under the given conditions of congruency, we can say that;
Line segment AB is longer than Line segment FD.
CongruencyThe image showing both triangles is missing and so i have attached it.
From the attached image, we see that BC is congruent to DE and AC is congruent to FE. Thus, if Angle BCA was congruent to angle DEF, then the it means that both triangles would be congruent as well, because it would satisfied the Side Angle Side (SAS) congruence postulate.Therefore, we can say that line AB and line FD do not have the same length.
Now, we see that angle BCA is larger than angle DEF, and as such we can say that the line segment AB is longer than line segment FD.

Find the quotient when P(x) is divided by the binomial following it. P(x)=x^(3)+3x^(2)-4;x-1 The quotient is
Answers
The quotient when P(x) = \(x^3\)+ 3\(x^{2}\) - 4 is divided by the binomial x - 1 is \(x^{2}\) + 4x + 7.
To find the quotient, we can use polynomial long division. The divisor is x - 1, which represents a binomial with a root at x = 1. We divide the polynomial P(x) = \(x^3\) + 3\(x^{2}\) - 4 by x - 1.
Starting with the highest power of x in P(x), which is \(x^3\), we divide \(x^3\) by x to get \(x^{2}\). We then multiply x - 1 by \(x^{2}\), resulting in \(x^3\) - \(x^{2}\). Subtracting this from P(x), we get 4\(x^{2}\) - 4. We bring down the next term, which is 0, and continue the process.
Next, we divide 4\(x^{2}\) by x to get 4x. We multiply x - 1 by 4x, yielding 4\(x^{2}\) - 4x. Subtracting this from 4\(x^{2}\) - 4, we get 4x - 4. Again, we bring down the next term, which is 0.
Finally, we divide 4x by x to get 4. We multiply x - 1 by 4, giving us 4x - 4. Subtracting this from 4x - 4, we get 0. Since there are no more terms to bring down, the process is complete.
The resulting quotient is \(x^{2}\)+ 4x + 7, indicating that P(x) = (x - 1)(\(x^{2}\) + 4x + 7), with a remainder of 0.

Answers
The area of the replica is approximately 1.33 square feet, Rounded to the nearest hundredth.
If the original artwork has an area of 12 square feet, then a replica created by dilating the original by a scale factor of 1/3 will have an area that is (1/3)^2 = 1/9 of the original area. Therefore, the area of the replica will be:
12 square feet × 1/9 = 4/3 square feet ≈ 1.33 square feet
A scale factor is a multiplier that scales or resizes a shape, figure, or object. It is used to determine the size of a new shape or figure when it is scaled up or down by a certain factor. The scale factor can be expressed as a ratio, a fraction, or a decimal. For example, if a rectangle has a length of 10 units and a width of 5 units, and it is scaled up by a factor of 2, the new rectangle will have a length of 20 units and a width of 10 units. The scale factor, in this case, is 2.
Scale factors are commonly used in geometry, especially in transformations such as dilation, which involves scaling a shape by a certain factor without changing its shape. Scale factors can also be used in real-world applications such as maps, where a scale factor is used to represent the ratio between the distance on the map and the actual distance on the ground.

Answers
The probability of a female student studying abroad is 9.5%. 60% of those who study abroad are female, while 49% of those who do not study abroad are female.
P(Female studying abroad) = P(Female and Studying Abroad) / P(Female)
P(Female and Studying Abroad) = 0.095 × 0.60 = 0.057
P(Female) = 0.095 × 0.60 + 0.905 × 0.49 = 0.902
P(Female studying abroad) = 0.057 / 0.902 = 0.063
Therefore, the probability of a female student studying abroad is 0.063.
The probability of a female student studying abroad is 9.5%. This means that out of all the undergraduate students, 9.5% of them are female and are studying abroad. It is also important to note that out of those who study abroad, 60% are female, while 49% of those who do not study abroad are female. This means that more female students are likely to study abroad than male students, as the percentage of female students studying abroad is higher than the percentage of male students studying abroad. It is also important to note that the overall percentage of female students studying abroad is lower than the overall percentage of male students studying abroad, as the number of female students who study abroad is lower than the number of male students who study abroad.

Answers
To determine the cost allocated to the land, we need to calculate the proportionate cost of the land in relation to the total appraised value of the real estate. Therefore, the cost allocated to the land is $32,500.
The total cost paid for the real estate is $310,000 plus $15,000 in closing costs, totaling $325,000. To allocate the cost to the land, we need to calculate the proportion of the land's appraised value to the total appraised value of the real estate.
The total appraised value of the real estate is the sum of the appraised values of the land, building, and land improvements, which amounts to $35,000 + $105,000 + $210,000 = $350,000.
To calculate the cost allocated to the land, we divide the appraised value of the land by the total appraised value of the real estate and multiply it by the total cost paid:
Cost allocated to land = (Appraised value of land / Total appraised value) * Total cost
= ($35,000 / $350,000) * $325,000
= 0.1 * $325,000
= $32,500
Therefore, the cost allocated to the land is $32,500. This allocation is based on the relative appraised value of the land compared to the total appraised value of the real estate.

On the other hand, if the magnitude of the negative integer is greater than the magnitude of the positive integer, the sum will be negative. In this case, the negative integer dominates and determines the sign of the sum.
In both scenarios, the sign of the larger magnitude integer takes precedence and determines the sign of the sum. It is important to note that the sum will always have the sign of the integer with the larger magnitude, regardless of the specific values of the integers involved.
By considering the magnitudes of the integers, we can easily determine the sign of their sum when one integer is positive and the other is negative.

You have $135 in a saving account and save $12 per week. Your friend has $95 in a savings account and saves $20 per week. How many weeks will it take for you and your friend to have the same balance?
Answers
Answer: It will take 5 weeks for you and your friend to have the same balance.
Step-by-step explanation:
Let x be the number of weeks.
Total money saved = Money in saving account + (Money saved per week)×(Number of weeks)
For you, Total money saved = 135 + 12x
For your friend , Total money saved = 95 + 20x
W hen they have equal amount int heir account , then
\(135+12x=95+20x\\\\\Rightarrow\ 135-95=20x-12x\\\\\Rightarrow\ 40= 8x\\\\\Rightarrow\ x=\dfrac{40}{8}=5\)
So, it will take 5 weeks for you and your friend to have the same balance.
