Answer: [tex]\int\limits^a_E {\int\limits^a_E {\int\limits^a_E {xy} } \, dV[/tex] = 1087.5

Step-by-step explanation: To evaluate the triple integral, first an equation of a plane is needed, since the tetrahedon is a geometric form that occupies a 3 dimensional plane. The region of the integral is in the attachment.

An equation of a plane is found with a point and a normal vector. Normal vector is a perpendicular vector on the plane.

Given the points, determine the vectors:

P = (5,0,0); Q = (0,9,0); R = (0,0,4)

vector PQ = (5,0,0) - (0,9,0) = (5,-9,0)

vector QR = (0,9,0) - (0,0,4) = (0,9,-4)

Knowing that cross product of two vectors will be perpendicular to these vectors, you can use the cross product as normal vector:

n = PQ × QR = [tex]\left[\begin{array}{ccc}i&j&k\\5&-9&0\\0&9&-4\end{array}\right][/tex][tex]\left[\begin{array}{ccc}i&j\\5&-9\\0&9\end{array}\right][/tex]

n = 36i + 0j + 45k - (0k + 0i - 20j)

n = 36i + 20j + 45k

Equation of a plane is generally given by:

[tex]a(x-x_{0}) + b(y-y_{0}) + c(z-z_{0}) = 0[/tex]

Then, replacing with point P and normal vector n:

[tex]36(x-5) + 20(y-0) + 45(z-0) = 0[/tex]

The equation is: 36x + 20y + 45z - 180 = 0

Second, in evaluating the triple integral, set limits:

In terms of z:

[tex]z = \frac{180-36x-20y}{45}[/tex]

When z = 0:

[tex]y = 9 + \frac{-9x}{5}[/tex]

When z=0 and y=0:

x = 5

Then, triple integral is:

[tex]\int\limits^5_0 {\int\limits {\int\ {xy} \, dz } \, dy } \, dx[/tex]

Calculating:

[tex]\int\limits^5_0 {\int\limits {\int\ {xyz} \, dy } \, dx[/tex]

[tex]\int\limits^5_0 {\int\limits {\int\ {xy(\frac{180-36x-20y}{45} - 0 )} \, dy } \, dx[/tex]

[tex]\frac{1}{45} \int\limits^5_0 {\int\ {180xy-36x^{2}y-20xy^{2}} \, dy } \, dx[/tex]

[tex]\frac{1}{45} [30375-60750+118462.5-39150][/tex]

[tex]\int\limits^5_0 {\int\limits {\int\ {xyz} \, dy } \, dx[/tex] = 1087.5

The volume of the tetrahedon is 1087.5 cubic units.

The tripple integration will be   [tex]\int\limits^a_E \int\limits^a_E \int\limits^a_E {xy} \, dV[/tex] = 1087.5

The triple integration is used to identify the volumes of the objects or for analyzing three dimension of the object.

n = 36i + 0j + 45k - (0k + 0i - 20j)

n = 36i + 20j + 45k

Equation of a plane is generally given by:

[tex]a(x-x_o)+b(y-y_o)+c(z-z_o)=0[/tex]

Then, replacing with point P and normal vector n:

[tex]36(x-5)+20(y-0)+45(z-0)=0[/tex]

The equation is: 36x + 20y + 45z - 180 = 0

x = 5

Then, triple integral is:

Calculating:

[tex]\int\limits^5_0 \int\int xy\ dzdydx[/tex]

[tex]\int\limits^5_0 \int\int xy\ (\dfrac{180-36x-20y}{45}-0)dydx[/tex]

Answer: Population

Step-by-step explanation: Population is refers to the whole or entire members or of a given set. This is different from a sample which is used to refer to members of a subset (a subset is a certain portion or fraction of an entire set). In the scenario above, since the evaluation was based on the entire number of registered voters in the country, this means we are referring to a population. The inference about the percentage of democratic voters was drawn from a pool of all the entire number of registered voters available in the country and not from a certain subset or portion of registered voters. Hence, the evaluated group is a population.

Answer:

Length = 20 metres

Width = 10 mteres

Step-by-step explanation:

Let the width be x metres

Let the length be 2x metres

Perimeter = 60 metres

therefore, by the problem ,

2(length+breadth)= perimeter

=>2(2x+x)=60

=>2 *3x=60

=>6x=60

=>x=10

length = 20 metres

width = 10 mteres

.066

1 Centimeter = 0.03280839895 Feet

The conversion of 2 centimeters into feet would be 0.066 feet.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

We have to determine the conversion of 2 centimeters into feet.

Since one centimeter = 0.03280839895 feet

Therefore two centimeters = 2×0.03280839895 feet

⇒ two centimeters = 0.0656167

Round the answer to the nearest hundredth.

⇒ two centimeters = 0.066

Therefore, the conversion of 2 centimeters into feet would be 0.066 feet.

Answer:

The weight of luggage for a flight with 142 passengers is 2,106

Step-by-step explanation:

The total weight of luggage stored in the baggage compartment can be estimated by the least squares regression equation:

y=118+14*x

where y is the total weight of luggage stored in the luggage compartment and x is the number of passengers on a bus.

If you want to predict the weight of luggage for a flight with 142 passengers, this means that x must have a value of 142. So, replacing in the expression:

y=118+14*142

you get:

y=118+1,988

y=2,106

The weight of luggage for a flight with 142 passengers is 2,106

Step-by-step explanation:

n = 1000

P (probability of those with account) = 23% = 0.23

q(probability of those without account) = 1-p = 0.77

a. We are expected to find the expected number of those without checking account

= n * q

= 1000 * 0.77

= 770

b. Standard deviation

The answer is 0.55 %

Step-by-step explanation:

ΣX = 815

[tex]$b= -\frac{725}{9779 \times 2702}$[/tex]

b = -0.0741

Answer:

x = 109/216

Step-by-step explanation:

Solve for x:

1/36 = 6 x - 3

Hint: | Reverse the equality in 1/36 = 6 x - 3 in order to isolate x to the left hand side.

1/36 = 6 x - 3 is equivalent to 6 x - 3 = 1/36:

6 x - 3 = 1/36

Hint: | Isolate terms with x to the left hand side.

Add 3 to both sides:

6 x + (3 - 3) = 3 + 1/36

Hint: | Look for the difference of two identical terms.

3 - 3 = 0:

6 x = 1/36 + 3

Hint: | Put the fractions in 1/36 + 3 over a common denominator.

Put 1/36 + 3 over the common denominator 36. 1/36 + 3 = 1/36 + (36×3)/36:

6 x = 1/36 + (36×3)/36

Hint: | Multiply 36 and 3 together.

36×3 = 108:

6 x = 1/36 + 108/36

Hint: | Add the fractions over a common denominator to a single fraction.

1/36 + 108/36 = (1 + 108)/36:

6 x = (1 + 108)/36

Hint: | Evaluate 1 + 108.

1 + 108 = 109:

6 x = 109/36

Hint: | Solve for x.

Divide both sides by 6:

x = (109/6)/36

Hint: | Multiply 36 and 6 together.

36×6 = 216:

Answer: x = 109/216

Answer:

  x = 109/216

Step-by-step explanation:

Add 3, divide by 6.

Answer:

[tex]|tv = 14[/tex]

Step-by-step explanation:

Given

[tex]|tv = x + 10[/tex]

[tex]|tu = 3x - 8[/tex]

[tex]|uv = 10[/tex]

Required

Determine length of tv

Length tv is calculated by adding lengths tu and uv.

In other words

[tex]tv = tu + uv[/tex]

Substitute values for tv, tu and uv

[tex]x + 10 = 3x-8+10[/tex]

Collect like terms

[tex]x - 3x = -8+10 -10[/tex]

[tex]-2x = -8[/tex]

Divide both sides by -2

[tex]x = 4[/tex]

Recall that [tex]|tv = x + 10[/tex]

Substitute 4 for x

[tex]|tv = 4 + 10[/tex]

[tex]|tv = 14[/tex]

Hence, the length of line segment tv is 14
