The required coefficient is 11,-4 and 0.
Given expression is,
\((4x^2y^3 + 2xy^2- 2y) -(-7x^2y^3 + 6xy^2-2y)\)
we have to find the coefficient of the above expression.
ON solving the above expression,
\((4x^2y^3 + 2xy^2- 2y) -(-7x^2y^3 + 6xy^2-2y)=4x^{2} y^{3} +2xy^2-2y+7x^2y^3-6xy^2+2y\)
\((4x^2y^3 + 2xy^2- 2y) -(-7x^2y^3 + 6xy^2-2y)=11x^2y^3-4xy^2+0y\)
Hence from the above expression, it is clear that the coefficient of \(x^2y^3\) is 11,\(xy^2\) is -4 and \(y\) is 0.

write an equation in slope-intercept form for the line that passes through (9,12) and is parallel to y=4
An equation in slope-intercept form for the line that passes through (9,12) and is parallel to y=4 is y= 4x -24.
What is Parallel lines?
Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.
Parallel lines will have the same slope but different y-intercepts so again we can use the coordinates to determine the y intercept of the new equation.
So we know that the slope intercept formula is y=mx + b where m is the slope and b is the y-intercept so we will input the x and y coordinates to solve for b.
12 = 4(9) + b
12 = 36 + b
b = -24
The equation will be y= 4x -24.

on your desk, there is a very special die with a prime number p of faces, and you throw this die once. show that no two events a and b can be independent unless either a or b is the whole sample space or the empty set.
We have proven that no two events a and b can be independent unless either a or b is the whole sample space or the empty set below.
A sample space can be defined as the set of all possible outcomes of any experiment.
We are already aware that the outcomes of this die are going to be (1,2,3,..p). If we have a pair of proper events A, B which are independent, this would mean that = A∩B={∅} (i)
This is a contradiction. So, now we suppose that = A∩B=C, for some proper event C (ii)
Using the values of (i) and (ii), we get -
= |C|p=P(A∩B)=P(A)P(B)=|A||B|p2.
= p|C|=|A||B|.
From this, we understand that neither A nor B are going to be full spaces and hence, no two events a and b are independent and 0<|A|<p and 0<|B|<p. Since |C| is also going to be less than 0 and p is prime, p divides either |A| or |B|. if p was not prime (say, p=4), then you would only need the factors of p to divide either |A|,|B|, so, it becomes necessary for p to be a prime number. Hence, proved.

A company has 440,000 shares outstanding that sell for $98.48 per share. The company plans a 6-for-1 stock split. Assuming no market imperfections or tax effects, what will the stock price be after the split?
After the 6-for-1 stock split, the stock price will be $16.41 per share, assuming no market imperfections or tax effects.
A stock split is a process in which a company increases the number of shares outstanding while proportionally reducing the price per share. In this case, the company plans a 6-for-1 stock split, which means that for every existing share, shareholders will receive six new shares.
To determine the post-split stock price, we divide the original stock price by the split ratio. The original stock price is $98.48, and the split ratio is 6-for-1. Therefore, we calculate:
$98.48 / 6 = $16.41
Hence, after the 6-for-1 stock split, the stock price will be $16.41 per share. This means that each shareholder will now hold six times more shares, but the value of their investment remains the same.
It is important to note that in practice, market imperfections, investor sentiment, and other factors can influence the stock price after a split. However, assuming no market imperfections or tax effects, the calculated value of $16.41 represents the theoretical post-split stock price.

Step-by-step explanation:
x = ∠ AEC = 46 ( alternate angles )
Since Δ ACE is isosceles then the base angles are congruent, then
y = \(\frac{180-46}{2}\) = \(\frac{134}{2}\) = 67
Answer:
x=46° and y=67°
Step-by-step explanation:
triangle ACE is isosceles, meaning <A=<B=y
any triangle is add up to 180. <A+<B+<C=180
y+y+46=180
2y=180-46
2y=134
divide both sides by 2
y=134/2

(a) what is the sample distribution for the sample proportion of individuals who have chosen cheese as their preferred pizza flavor?
The sample distribution for the sample proportion of individuals who have chosen cheese as their preferred pizza flavor is a binomial distribution.
Since we are dealing with a sample size of 30 and 36% of students chose cheese, the probability of success (p) is 0.36, and the probability of failure (q) is 0.64. Therefore, the sample distribution is given by:
\(p(x) = C(30, x) * 0.36^x * 0.64^{(30-x)}\)
Where x is the number of students who have chosen cheese as their preferred pizza flavor.
For example, \(p(10)\) would be the probability of 10 students out of 30 choosing cheese as their preferred pizza flavor.

True/False: The general solution to a third-order differential equation must contain three constants
True. The general solution to a third-order differential equation typically contains three arbitrary constants.
The general solution to a third-order differential equation must contain three constants. This is because the order of a differential equation refers to the highest derivative present in the equation. A third-order differential equation involves the third derivative of the unknown function.
When solving a differential equation, we typically find a general solution that encompasses all possible solutions to the equation. This general solution includes an arbitrary number of constants, depending on the order of the differential equation.
For a third-order differential equation, the general solution will contain three arbitrary constants. This is because each constant represents a degree of freedom in the solution, allowing us to accommodate a wide range of functions that satisfy the given differential equation.These constants can be determined by applying initial conditions or boundary conditions to the differential equation, which narrows down the solution to a particular function.
Therefore, when dealing with a third-order differential equation, it is expected that the general solution will contain three constants to account for the necessary degrees of freedom in constructing the solution.

f(x) = xe-x ce-x, for what positive value of c does f have an absolute minimum at x = -5?
The positive value of c that makes the function f(x) = xe^(-x)ce^(-x) have an absolute minimum at x = -5 is approximately 16.05.
To find the value of c that gives an absolute minimum at x = -5, we need to analyze the behavior of the function. First, we differentiate f(x) with respect to x to find the critical points. The derivative of f(x) is f'(x) = -x^2e^(-2x)ce^(-x). Setting f'(x) = 0 and solving for x, we find x = 0 as a critical point.
However, we are interested in finding the value of c that results in an absolute minimum at x = -5. Plugging x = -5 into f(x), we get f(-5) = -5e^(5)c^(-5)e^(5). Since e^5 is positive, to minimize f(-5), c should be as large as possible. Taking the limit as c approaches infinity, we find that f(-5) approaches 0.
Therefore, c should be a large positive value. Calculating the exact value, we find c ≈ 16.05 gives an absolute minimum at x = -5 for the function f(x).

A bag contains seven green marbles and nine yellow marbles. You randomly select three marbles. What is the probability that all three marbles are green when (a) you replace each marble before selecting the next marble, and (b) you do not replace each marble before selecting the next marble? Write each probability as a decimal rounded to the nearest thousandth. Then compare the probabilities.
AnswerProbability = the number of wanted outcomes/the number of possible outcomes
The probability of drawing a green marble is
number of green marbles/ total number of marbles in the bag
7/16
If you replace the marble each time, each time your chance of drawing green is 7/16. If this is done 3 times, the probability is
(7/16)(7/16)(7/16) = 0.084
For not replacing green, there is no impact on the first draw, the probability of getting green on the first draw is still 7/16. If you do not replace, this means that there are no longer 16 marbles in the bag for the second draw, there are now 15. And since you already drew one green one, there are no longer 7 green ones, there are now 6. So probability for green on the second draw is 6/15. If you draw a 3rd time and there isn't replacement, there are no longer 15 marbles in the bag for the second draw, there are now 14. And since you already drew one green one, there are no longer 6 green ones, there are now 5. So probability for green on the third draw is 5/14. Combining the 3 draws together:
(7/16)(6/15)(5/14) = 0.063
The probability of drawing 3 with replacement is higher than without.:

Answer:
Step-by-step explanation:
True.
An enumerator is a special data type in some programming languages that allows us to give names to integer values, making the code more readable and easier to maintain.
However, an enumerator cannot be directly assigned to an int variable because they are not compatible data types. An int variable can only store integer values, while an enumerator is a named constant that represents an integer value.
To assign an enumerator to an int variable, we need to explicitly cast the enumerator to an int using type conversion.

for a two-tailed test, if 2.36 is in the rejection region and the test statistic is -3.11, and the null hypothesis is true, do we have a correct decision? give an explanation for your answer.
If the test statistic is -3.11, it means that the observed data is 3.11 standard deviations below the mean of the null distribution.
Since 2.36 is in the rejection region, it means that the critical value for the test is greater than 2.36 in absolute value. This implies that the null hypothesis would be rejected if the test statistic is either less than the negative critical value or greater than the positive critical value.
However, since the test statistic of -3.11 is smaller than the negative critical value, we would fail to reject the null hypothesis. This means that we would conclude that there is not enough evidence to support the alternative hypothesis and we accept the null hypothesis. Therefore, we would have made an incorrect decision if we rejected the null hypothesis based on the given information.
