Step-by-step explanation:

differentail equation:

[tex]yu_{xy} + u = 0..........(1)[/tex]  

when [tex]u(x,y) = X(x)Y(y)[/tex]

[tex]u_x = \frac{\partial u}{\partial  x} X'Y' \\\\ u_{xy} = \frac{\partial^2 u }{ \partial x\ \partial  y}= X'Y'[/tex]

by substituting the value we get:

[tex]\to \int \frac{Y'}{Y} = -\lambda \int \frac{1}{y} dy\\\\[/tex]

by solving the value:

[tex]\to Y=c_3 y^{-\lambda}\\\\\therefore\ \ c_4=c_2C_3\\\\\to u(x,y) = c_4 e^{\frac{x}{\lambda}} y^{-\lambda}[/tex]

The solution of the given partial differential equation will be

[tex]u(x,y)=c_4e^\frac{x}{\lambda}y^{-\lambda}[/tex]

The partial derivative is a way to find the slope in either the x or y direction, at the point indicated.

[tex]yu_{xy}+u=0..............................(1)[/tex]

Now if [tex]u(x,y)=X(x)Y(y)[/tex]

[tex]u_x=\dfrac{\partial u}{\partial x} X'Y'[/tex]

[tex]u_{xy}=\dfrac{\partial^2u}{\partial x\ \partial y}=X'Y'[/tex]

by substituting the value, we get:

[tex]\int \dfrac{Y'}{Y}=-\lambda\int\dfrac{1}{y}dy[/tex]

by solving the value:

[tex]Y=c_3y^{-\lambda}[/tex]

[tex]c_4=c_2c_3[/tex]

[tex]u(x,y)=c_4e^\frac{x}{\lambda}y^{-\lambda}[/tex]

Hence the  solution of the given partial differential equation will be

[tex]u(x,y)=c_4e^\frac{x}{\lambda}y^{-\lambda}[/tex]

Step-by-step explanation:

-6(2x-5)

-6(2x+5)

-6(2x) + 6(5)

-12x +30

Using specific examples, the unit rate can be obtained using equivalent ratio tables and fraction thus :

Table of equivalent ratios :

No of workers : ____ 2 ____ 4 ____ 6 ____ 8

Logs of wood cut: __ 4 ____ 8 ____12 ____16

To obtain the unit rate from the table :

Take the ratio of any pair of values ;

Hence, the unit rate is 2 logs of wood per worker.

Using the fractions :

2 worker = 4 logs of wood

1 worker = x

Cross multiply

2x = 4

x = 4/2

x = 2 logs of wood.

Hence, the unit rate is 2 logs of wood per worker.

Answer:

y = 12.5

Step-by-step explanation:

Notice these are similar triangles since they have angles of the same measure (congruent angles), then there must be a proportion among their sides such that:

[tex]\frac{y+5}{5} =\frac{14}{4}[/tex]

therefore by cross-multiplying, we get:

4(y + 5) = 14 * 5

4 y + 20  = 70

4 y = 70 - 20

4 y = 50

y = 12.5

This question is incomplete, the complete question is;

In a survey, 55% of the voters support a particular referendum. If 40 voters are chosen at random,

find the mean and variance for the number of voters who support the referendum.

Answer:

a) The Mean is 22

b) Variance is 9.9

Step-by-step explanation:

Given that;

55% of the voters support a particular referendum p = 0.55

q = 1 - p = 1 - 0.55 = 0.45

sample size n = 40

a)

Mean = sample size n × p

Mean = 40 × 0.55

Mean = 22

Therefore the Mean is 22

b)

Variance = n × p × q

so we substitute

Variance = 40 × 0.55 × 0.45

Variance = 9.9

Therefore the Variance is 9.9

Complete Question

A panel of 12 jurors needs to be selected from a group of 30  people. How many different compositions for the jury are possible?

A. 479,001, 600.

B. 18, 564.

C. 41, 430, 393, 164, 160,000.

D. 86, 493, 225.

Answer:

The correct option is D

Step-by-step explanation:

From the question we are told that

   The number of jurors to be selected is q = 12

   The total number of people available n =  30  

Generally the number of different compositions for the jury that is possible is mathematically represented as

         [tex]N = ^nC_q[/tex]

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

        [tex]N = ^{30}C_{12}[/tex]

=>     [tex]N = 86,493,225[/tex]

Answer:

Step-by-step explanation:

When we look at sequences, we have the function and we have the sequence, the sequence is f(x)... f(n)... or just f with any variable within a parenthesis right next to it.

What the variable signifies is the value that we will be replaced within the sequence, which is 2n in this case. So by your question, it we are looking for the fourth term, that means f(4) = 2n.  Since n is replaced with 4, we do the same with the sequence.
