The correct statement is c. The Adjusted R-squared is a measure used in multiple regression analysis that is between 0 and 1. It is different from the R-squared value in simple linear regression.

The Adjusted R-squared can decrease if the addition of another X regressor does not sufficiently lower the sum of squared residuals (SSR) relative to the impact of increasing the number of predictors (k). It measures the proportion of the variance explained by the predictors, adjusted for the number of predictors and the sample size, rather than the ratio of the sum of squared residuals to the total sum of squares. It provides a measure of how well the regression model fits the data, and it ranges between 0 and 1. A value closer to 1 indicates that a higher proportion of the variance in the dependent variable is explained by the predictors.

Adding another X regressor to the multiple regression model can impact the Adjusted R-squared. If the additional regressor does not significantly contribute to reducing the sum of squared residuals (SSR) relative to the increase in the number of predictors (k), the Adjusted R-squared can decrease. This means that the added regressor does not improve the model's ability to explain the variance in the dependent variable adequately.

However, the Adjusted R-squared does not directly measure the ratio of the sum of squared residuals to the total sum of squares. Instead, it represents the proportion of the variance explained by the predictors, adjusted for the number of predictors and the sample size. It penalizes models with a large number of predictors that may overfit the data, thereby providing a more reliable measure of the model's goodness of fit.

To find the probability of more than 4 delinquent card payments out of 8 randomly selected adults with a 30% delinquency rate, we can use the binomial distribution formula. First, we need to calculate the probability of exactly 4 delinquent card payments, which is:

P(X=4) = (8 choose 4) * (0.3)^4 * (0.7)^4 = 0.278
where "8 choose 4" represents the number of ways to choose 4 out of 8 adults. Then, we need to calculate the probability of 3 or fewer delinquent card payments:
P(X<=3) = P(X=0) + P(X=1) + P(X=2) + P(X=3) = 0.149
where "P(X=k)" represents the probability of exactly k delinquent card payments. Finally, we can subtract this probability from 1 to get the probability of more than 4 delinquent card payments:
P(X>4) = 1 - P(X<=3) = 0.851
Therefore, the probability of more than 4 delinquent card payments out of 8 randomly selected adults with a 30% delinquency rate is 0.851.

Differentiation is the rate at which a function changes with regard to a variable in mathematics (in mathematics, the rate of change of a function with respect to a variable). Problems involving calculus and differential equations need the use of derivatives.

The sample variance, s2, for the given data is 1.44. The sample standard deviation, s, is 1.20. The definition formula for sample variance is: s2 = 1/(n - 1) * sum((xi - xbar)^2) where xi is the ith measurement, xbar is the sample mean, and n is the sample size.

In this case, the sample mean is xbar = 2.5. So, the definition formula gives us:

s2 = 1/(5 - 1) * sum((xi - 2.5)^2) = 1.44

The computing formula for sample variance is:

s2 = 1/(n - 1) * (sum(xi^2) - (xbar^2))

In this case, the computing formula gives us the same answer:

s2 = 1/(5 - 1) * (sum(xi^2) - (2.5^2)) = 1.44

The sample standard deviation is simply the square root of the sample variance. So, s = 1.20.

Therefore, the sample variance, s2, for the given data is 1.44 and the sample standard deviation, s, is 1.20.

The body surface area (BSA) of patient Z is 2.44 square meters, the height of patient Y is 182 cm, the weight of a patient with a BSA of 2.2 square meters is 181 pounds, and patient X will receive 4.8 mg of drug A based on their BSA of 1.92 square meters and the prescribed dosage of 2.5 mg per square meter.

Part 1: To calculate BSA for patient Z, we plug in the given values into the formula:  \(BSA =\frac{w^{0.425} \times h^{0.725}}{3600 } = \frac{240^{0.425} \times 183^{0.725}} {3600} = 2.44 m2\).

Part 2: To solve for the height of patient Y, we plug in the given values into the formula and solve for h: \(BSA =\frac{w^{0.425}\times{h^{0.725}}}{3600}= \frac{185^{0.425}\times h^{0.725}}{3600} = 2.2 m2\) . We can then rearrange the formula to solve for h: \(h = (\frac {3600 \times BSA}{w^{0.425}})^{\frac{1}{0.725}} = (\frac{3600 \times 2.2}{ 185^{0.425}})^ {\frac{1}{0.725} = 182 cm.\)

Part 3: To solve for the weight of a patient with a given BSA, we plug in the given values into the formula and solve for w: \(BSA = (w^{0.425} * h^{0.725} \div 3600 = w^{0.425} * 183^{0.725} \div3600 = 2.2 m2.\)

We can then rearrange the formula to solve for w: \(w= (\frac{3600 \times BSA}{h^{0.725}})^{\frac{1}{0.425}}=(\frac{3600\times 2.2}{183^{0.725}})^\frac{1}{0.425} = 181 pounds.\)

Part 4: To calculate the amount of drug A that patient X will receive, we first need to calculate their BSA using the formula: \(BSA = \frac {w{^{0.425}} \times h^{0.725}}{3600} = \frac {150^{0.425} \times 175^{0.725}}{3600} = 1.92 m2\). We can then multiply this value by the drug dosage per square meter to get the total amount of drug A patient X will receive: 1.92 m2 * 2.5 mg/m2 = 4.8 mg.

Answer:

y - 7 = - \(\frac{5}{2}\) (x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - \(\frac{5}{2}\) and (a, b ) = (- 2, 7 ) , then

y - 7 = - \(\frac{5}{2}\) (x - (- 2) ) , that is

y - 7 = - \(\frac{5}{2}\) (x + 2)

The total number (n) of distinct solutions of the equation (x + y + z = 15) with the assumption that x, y and z are all nonnegative integers is 153.

The generating function for the number of solutions of the equation (x + y + z = n) is given by the binomial coefficient (n+2)C2, where C2 is the number of ways to choose 2 objects from a set of n+2 objects.

The number of solutions for the given equation (x + y + z = 15) is then given by:

(15+2)C2 = (17C2)

We can also use the formula for binomial coefficient: nCr = n! / (r! (n-r)!)

17C2 = (17!) / (2! * 15!) = 153

So the total number of distinct solutions of the equation (x + y + z = 15) with x, y, z non-negative integers is 153.

Answer:

I attached a graph to the problem, so you can better understand why there is no solution to the system of equations:

The graph of the two lines shows that the two lines are parallel lines and never intersect.  We know (even without writing the second equation in slope-intercept form) that parallel lines have the same slope and will never intersect, so the two lines have the same slope.  Graphically, a system of equations can only have a solution, when the two lines intersect at one point or intersect at infinitely many points.  Had the two lines had the same y-intercept, they would no longer be parallel lines, as they would overlap and thus would have infinitely many solutions.  Because this is not the case, there are no solutions to the system of equations.

The curve is concave upward on this interval. In interval notation, the answer is:(0, pi/2)

To find dy/dx, we use the chain rule:

dy/dt = -sin(t)

dx/dt = -sin(2t)

Using the chain rule,

dy/dx = dy/dt / dx/dt = -sin(t) / sin(2t)

To find d2y/dx2, we can use the quotient rule:

d2y/dx2 = [(sin(2t) * cos(t)) - (-sin(t) * cos(2t))] / (sin(2t))^2

= [sin(t)cos(2t) - cos(t)sin(2t)] / (sin(2t))^2

= sin(t-2t) / (sin(2t))^2

= -sin(t) / (sin(2t))^2

To determine where the curve is concave upward, we need to find where d2y/dx2 > 0. Since sin(2t) is positive on the interval (0, pi), we can simplify the condition to:

d2y/dx2 = -sin(t) / (sin(2t))^2 > 0

Multiplying both sides by (sin(2t))^2 (which is positive), we get:

-sin(t) < 0

sin(t) > 0

This is true on the interval (0, pi/2). Therefore, the curve is concave upward on this interval.

In interval notation, the answer is: (0, pi/2)
