The correlation coefficient ρ for X and Y is ρ = -0.6675 in the given function.
What is correlation coefficient?The correlation coefficient is a statistical concept that aids in establishing a relationship between expected and actual values obtained through statistical experimentation. The calculated correlation coefficient's value explains why the difference between the predicted and actual values is so exact.
Correlation Coefficient value is always in the range of -1 to +1. A similar and identical relationship exists between the two variables if the correlation coefficient value is positive. Otherwise, it reveals how differently the two variables behave.
Pearson's correlation coefficient is calculated by taking the covariance of two variables and dividing it by the sum of their standard deviations. is typically used to represent it (rho).
The correlation coefficient is computed as,
\($ \rho & =\frac{{Cov}(X, Y)}{\sqrt{V(X)} \times \sqrt{V(Y)}}\)
\($=\frac{-0.0267}{\sqrt{0.04} \times \sqrt{0.04}}\)
= -0.6675
Thus, the correlation coefficient ρ for X and Y is ρ = -0.6675.

Answers
The problem can be solved using the simplex method, and the solution can be verified using the graphical method. The optimal solution is X1 = 6, X2 = 0, X3 = 6, Z = 24.
The problem can be solved using the simplex method, and verified using the graphical method. Here are the steps:
Convert the problem to standard form by introducing slack variables:
Min Z = -2X1 - 4X2 - 3X3 + 0S1 + 0S2 + 0S3
St. X1 + 3X2 + 2X3 + S1 = 30
X1 + X2 + X3 + S2 = 24
3X1 + 5X2 + 3X3 + S3 = 60
Xi, Si >= 0
Set up the initial simplex tableau:
| 1 3 2 1 0 0 30 |
| 1 1 1 0 1 0 24 |
| 3 5 3 0 0 1 60 |
| 2 4 3 0 0 0 0 |
Identify the entering variable (most negative coefficient in the objective row): X2
Identify the leaving variable (smallest ratio of RHS to coefficient of entering variable): S1
Pivot around the intersection of the entering and leaving variables to create a new tableau:
| 0 2 1 1 -1 0 6 |
| 1 0 0 -1 2 0 18 |
| 0 0 0 5 -5 1 30 |
| 2 0 1 -2 4 0 36 |
Repeat steps 3-5 until there are no more negative coefficients in the objective row. The final tableau is:
| 0 0 0 7/5 -3/5 0 18 |
| 1 0 0 -1/5 2/5 0 6 |
| 0 0 1 1/5 -1/5 0 6 |
| 0 0 0 -2 4 0 24 |
The optimal solution is X1 = 6, X2 = 0, X3 = 6, Z = 24.
To verify the solution using the graphical method, plot the constraints on a graph and find the feasible region. The optimal solution will be at one of the corner points of the feasible region. By checking the values of the objective function at each corner point, we can verify that the optimal solution found using the simplex method is correct.
In conclusion, the problem can be solved using the simplex method, and the solution can be verified using the graphical method. The optimal solution is X1 = 6, X2 = 0, X3 = 6, Z = 24.

Each peach costs same amount .
Work out cost of one peach .

intersecting lines r, s, and t are shown below. s t 23° r 106° x° what is the value of x ?
Answers
To find the value of x, we need to use the fact that when two lines intersect, the sum of the adjacent angles formed is equal to 180 degrees.
In this case, the angle formed between lines s and t is 23 degrees, and the angle formed between lines r and s is 106 degrees. Let's denote the angle between lines t and r as x.
Using the information given, we can set up the equation:
(106 degrees) + (23 degrees) + x = 180 degrees
Combine the known values:
129 degrees + x = 180 degrees
To isolate x, subtract 129 degrees from both sides of the equation:
x = 180 degrees - 129 degrees
x = 51 degrees
Therefore, the value of x is 51 degrees.
In conclusion, the value of x, the adjacent angles formed between intersecting lines t and r, is 51 degrees.

The equations that are parallel to the given line are C. 6x + 2y = -4 and D. 6x - 2y = -4.
What is the slope-intercept form?
The slope-intercept form of an equation is y = mx + b, where m is the slope and b is the y-intercept.
Two lines are parallel if they have the same slope. The given line y = 3x - 5 is in slope-intercept form, which means its slope is 3.
A line in slope-intercept form has the equation y = mx + b, where m is the slope and b is the y-intercept. Therefore, any line of the form y = 3x + c, where c is a constant, will have a slope of 3 and be parallel to the given line.
Let's check each of the given equations to see which ones are of this form:
A. y = 3x - 7: This equation has the same slope as the given line, but it is not in the form y = 3x + c. Therefore, it is not parallel to the given line.
B. y = -3x - 5: This equation has a slope of -3, which is not the same as the slope of the given line. Therefore, it is not parallel to the given line.
C. 6x + 2y = -4: We can rearrange this equation to slope-intercept form by solving for y:
2y = -6x - 4
y = -3x - 2
This equation has the same slope as the given line, so it is parallel to the given line.
D. 6x - 2y = -4: We can rearrange this equation to slope-intercept form by solving for y:
-2y = -6x - 4
y = 3x + 2
This equation has the same slope as the given line, so it is also parallel to the given line.
Therefore, the equations that are parallel to the given line are C. 6x + 2y = -4 and D. 6x - 2y = -4.

Two players take turns removing a ball from a jar that initially contains m white and n black balls. The rst player to remove a white ball wins. Find the probability that the starting player wins.
Answers
½×½ which will be ¼
Step-by-step explanation:
because
Probability that the starting player wins:
\(P_{n} =\) m /n + m + n(n-1) /(n + m)(n+m -1) × \(P_{n-2}\)
Let us say that the probability that the first player wins is \(P_{n}\). Then this can be happen in two ways:
If the first player wins in the first move which has a probability: m /n + m
If the first player wins after the second move which has a probability :
n(n-1) /(n + m)(n+m -1) × \(P_{n-2}\)
Therefore by the law of probability,
\(P_{n} =\) m /n + m + n(n-1) /(n + m)(n+m -1) × \(P_{n-2}\)

Solve for a

Answers
Answer:
a = -30
Step-by-step explanation:
In order to solve for a in the equation \(\sf 11 = \dfrac{-3}{10} a + 2\), we can follow these steps:
Subtract 2 from both sides of the equation:
\(\sf 11 -2= \dfrac{-3}{10} a + 2-2\)
\(\sf 9 = \dfrac{-3}{10} a\)
Multiply both sides of the equation by \(\sf -\dfrac{10}{3}\):
\(\sf 9 *-\dfrac{10}{3}= \dfrac{-3}{10} a*-\dfrac{10}{3}\)
-30 = a
Therefore, the solution to the equation 11 a + 2\(\sf \dfrac{-3}{10} a + 2\) is a = -30.

First, you can simplify each square root:
√2 = 1.4142 (rounded to 4 decimal places)
3√5 = 5.1962 (rounded to 4 decimal places)
Next, you can multiply the two simplified square roots and the whole number:

Always true. The sum of the measures of the interior angles of any triangle is 180 degrees, so when one angle is 120 degrees, the remaining two angles must add to 60 degrees.
The sum of the measures of the interior angles of any triangle is 180 degrees. This is because the angles of a triangle add up to form a straight line, which is 180 degrees. Therefore, if one angle has a measure of 120 degrees, the remaining two angles must add up to the remaining 60 degrees to make 180 degrees in total. This means that the measure of angle 1 must be 60 degrees. Therefore, it is always true that when the measure of angle 4 is 120 degrees, the measure of angle 1 is 60 degrees. This is because the total sum of the interior angles of a triangle must add up to 180 degrees, so the other two angles must add up to the remaining 60 degrees.
