The probability for the bear visits using Poisson process of rate one visits per month is given by ,

P(X=i, Y=j) j=i                            j=2i                                        j=3i

X=i              e^(-1)(1/ i!) × 1/3^i 1/3^i + 4/3^(i-1) × e^(-1)/i!     2/3^i× e^(-1)/i!

Bear visits form a Poisson process of rate 1 visit per month.

Number of visits in a month  = Poisson distribution with parameter λ = 1.

Let X be the number of visits in a month.

And Y be the total number of bears in the month.

Probability of X and Y is equal to ,

P(X = i, Y = j), for i = 0, 1, 2, 3 and j = i, 2i, or 3i.

Law of total probability for  P(X = i, Y = j) for each i and j.

P(X = i, Y = i)

= P(X = i) × P(Y = i | X = i)

= e^(-λ) × λ^i / i! × 1/3^i

= e^(-1) × 1^i / i! × 1/3^i

= e^(-1) (1/ i!) × 1/3^i

Now,

P(X = i, Y = 2i)

= P(X = i) × P(Y = 2i | X = i)

= e^(-λ) × ( λ^i / i!) ×  [(1/3)^i + 2(1/3)^(i-1)(2/3)]

= e^(-1) / i! × [1/3^i + 4/3^i-1]

For,

P(X = i, Y = 3i)

= P(X = i) × P(Y = 3i | X = i)

= e^(-λ) × λ^i / i! × (1/3)^i × 2

= 2e^(-1) / i! × 1/3^i

Therefore, the probability of the size of bears for given condition is equal to,

P(X=i, Y=j) j=i                            j=2i                                        j=3i

X=i              e^(-1)(1/ i!) × 1/3^i 1/3^i + 4/3^(i-1) × e^(-1)/i!     2/3^i× e^(-1)/i!

The given question is incomplete, I answer the question in general according to my knowledge:

A village in Alaska is sometimes visited by polar bears. In fact, bear visits form a Poisson process of rate 1 visits per month. At each visit a group of bears shows up; the size of a group is equal to 1,2, or 3 with equal opportunity. Find the probability for each size.

After evaluating using the correct order of operations, the result will become 22/9.

The correct order of operations is to perform any calculations inside parentheses first, then exponents, then multiplication and division from left to right, and finally addition and subtraction from left to right. This order of operations is known as PEMDAS. Using this order, we can evaluate the expression as follows:

(17)/(18) + (6)/(35) ÷ (5)/(7) x (25)/(4)

Divide 6/35 by 5/7 by multiplying 6/35 by the reciprocal of 5/7.
= (17/18) + (6/35) x (7/5) x (25/4)
= (17/18) + (6/25) x (25/4)

Multiply 6/25 by 25/4.
= (17/18) + (6/4)

Finally, add 17/18 and 6/4 together.
= 22/9

Therefore, the final answer is 22/9,

The average percentage change in population from 2000-20009 is 1.36%.

A figure or ratio stated as a fraction of 100 is called a percentage. Frequently, it is indicated with the per cent sign, "%". If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage, therefore, refers to a component per hundred. Per 100 is what the word per cent means. As there is no unit of measurement for percentages, they are dimensionless numbers. This is because we divide numbers with the same units in percentage calculation.

a) Average percentage change

= Sum of percentage change in each year/number of years

= (1.97+1.71+1.65+1.42+1.22+1.02+1.07+1.22+0.93) / 9

= 1.36%

Therefore the average percentage change in population from 2000-20009 is 1.36%.

Step-by-step explanation:

3.

the sum of all internal angles in a quadrilateral is always 360°.

so, the internal angle at x is given by

360 = 40 + 80 + 110 + inner angle

inner angle = 360 - 40 - 80 - 110 = 130°

an inner and an outer angle combined are together always 180°.

so,

130 + x = 180

x = 50°

4.

first, again, the sum of all inner angles is 360°.

this is a parallelogram. that means the diagonally opposing angles are equal.

so, the angle opposite of the 38° angle is also 38°.

that leaves

360 - 38 - 38 = 284°

for the 2 (again equal) remaining angles :

284 = 2 × angle

each of these remaining angles is then

284/2 = 142°

the angle JML is one of them.

so,

angle JML = 142°

The expression which represents t as the subject of the formula is; t = (p + 4s) / √(s (3s - p)).

As evident in the task content; it follows that the expression which represents t as the subject of the formula is to be determined.

Given; ( (p + 4s) / t )² = s (3s - p)

(p + 4s) / t = √(s (3s - p))

t = (p + 4s) / √(s (3s - p))

Ultimately, the correct expression is; t = (p + 4s) / √(s (3s - p)).

Answer:

The given information that the graph of a polynomial function continues down on the left and continues up on the right is an indication that the degree of the polynomial is odd.

If the degree of the polynomial is odd, then the leading coefficient must be either positive or negative depending on the end behavior of the graph.

Since the graph continues down on the left and up on the right, the end behavior indicates that the leading coefficient is negative.

Therefore, the only option that satisfies the given information is:

d) The function is odd, with a negative leading coefficient.

The height in meters is 1.73 meters (rounded to two decimal places), the weight in other unit (kg) approximately 92.1 kg.The distance ran is approximately 546 meters

The distance you have run is 597 yards. To convert yards to meters, we can use the conversion factor 1 yard = 0.9144 meters. Therefore, the distance you have run in meters is approximately 546 meters (rounded to the nearest meter).

Your weight is currently expressed in pounds (lbs). To express your weight in other units, we can use conversion factors. For example, your weight in kilograms (kg) can be found by multiplying your weight in pounds by 0.453592. Using this conversion, your weight would be approximately 92.1 kg (rounded to one decimal place). Alternatively, your weight in stones (st) can be found by dividing your weight in pounds by 14.

A. The amount of aspirin in the dose is 22.066 milligrams.

B. ƒ (60) = 7.483 milligrams
This means that 60 hours after ingesting a dose of 22.066 milligrams of aspirin, the amount of aspirin in the person's blood will be 7.483 milligrams.

C. The aspirin level will be less than 10 milligrams after approximately 45.06 hours.

a. The initial amount of aspirin in the dose can be found by evaluating f(0):

f(0) = 300 * (1/2)^(1/30) ≈ 22.066

Therefore, there are approximately 22.066 milligrams of aspirin in the dose.

b. We can find f(60) by substituting t = 60 into the equation:

f(60) = 300 * (1/2)^(1/30 * 60) ≈ 7.483

Therefore, there are approximately 7.483 milligrams of aspirin in the person's blood 60 hours after ingesting the dose. This is significantly less than the initial amount of 22.066 milligrams, indicating that the aspirin is being metabolized and eliminated from the body over time.

c. We want to solve for t when f(t) < 10:

300 * (1/2)^(1/30t) < 10

Dividing both sides by 300:

(1/2)^(1/30t) < 1/30

Taking the natural logarithm of both sides:

ln[(1/2)^(1/30t)] < ln(1/30)

Using the properties of logarithms:

(1/30t)ln(1/2) < ln(1/30)

Simplifying:

-0.6931t < ln(1/30)

Dividing both sides by -0.6931 (which is ln(1/2)):

t > ln(1/30) / (-0.6931)

t > 45.06

The polynomial of best fit for a set of points is the polynomial that most closely fits the points. In order to find the polynomial of best fit, we need to use the method of least squares. This involves finding the coefficients a0, a1, and a2 that minimize the sum of the squared differences between the actual y-values and the predicted y-values of the polynomial.

1. First, we need to set up a system of equations using the given points:
a0 + a1(x1) + a2(x1)^2 = y1
a0 + a1(x2) + a2(x2)^2 = y2
a0 + a1(x3) + a2(x3)^2 = y3

2. Next, we need to solve this system of equations for a0, a1, and a2. This can be done using matrix operations or by using substitution and elimination.

3. Once we have found the values of a0, a1, and a2, we can plug them back into the equation for the polynomial of best fit:
p(x) = a0 + a1x + a2x^2

4. Finally, we can use this polynomial to make predictions for other x-values and compare them to the actual y-values to see how well the polynomial fits the data.

After comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.

A transformation known as a rotation involves turning the figure either clockwise or counterclockwise. The centre of rotation is the fixed location where the rotation occurs. The term "angle of rotation" refers to the amount of rotation. A figure can be rotated 90 degrees, or a quarter turn, in either a clockwise or counterclockwise direction.

You have rotated the figure 180 degrees when you have spun it exactly halfway. The figurine may be rotated 360° by turning it all the way around. A counterclockwise turn has a positive magnitude because a clockwise rotation indicates a negative magnitude. Rotational symmetry exists in every regular polygon. When an object is rotated around its centre, it retains its original appearance. The object is then referred regarded as having rotational symmetry.

Let's write the coordinates of the original figure,

A = (1, -5)

B = (6, -2)

C = (6, -5)

D = (1, -8)

Now, if we rotate it 90 degrees counterclockwise, the coordinates are:

A' = ( 5, 1)

B' = (2, 6)

C' = (5, 6)

D' = (8, 1)

Now if we rotate it again 90 degrees counterclockwise, the coordinates are:

A'' = ( -1, 5)

B'' = (-6, 2)

C'' = (-6, 5)

D'' = (-1, 8)

Now from the figure, let's write the coordinates.

A' = ( -1, 5)

B' =  (-6, 2)

C' = (-6, 5)

D' =  (-1, 8)

This is the same as the coordinates of the second 90 degrees counterclockwise rotation.

Since we did two 90 degrees rotations, we can say we did a total of 180° counterclockwise rotation.

Therefore after comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.

1. First, we need to distribute the exponent of -4 to each term inside the parentheses. This will give us:

(4^(-4))(x^(2*-4))(z^(-4*-4))/(20^(-4))(y^(-3*-4))

2. Next, we need to simplify the exponents by multiplying them. This will give us:

3. Now, we need to simplify the terms with negative exponents by moving them to the opposite side of the fraction. This will give us:

[tex](z^(16))(y^(12))/(4^(4))(x^(8))(20^(4))[/tex]

4. Finally, we need to simplify the terms with the same base by adding their exponents. This will give us:
[tex](z^(16))(y^(12))/(4^(4))(x^(8))(2^(8))(5^(8))[/tex]

5. We can further simplify the expression by simplifying the terms with the same base. This will give us:

Check the picture below.

we have three sides, let's look at the two smaller sides first, 1.9 and 2.7.

if we move the sides closer and ever closer to each other, to the extent that one is right on top of the other, what is the length of the red side?  Well, assuming the two smaller sides are one pancaked on top of the other, the red side will be as long as 2.7 - 1.9 = 0.8.  However, the sides can't be on top of each other, because if that's so, we have a flat-line, and thus we wouldn't have a triangle.  So whatever the third side may be, it must be greater than 0.8.

Now, if we move the sides away from each other, farther and farther to the extent that one is parallel to the other, then the third side will just be as long as 1.9 + 2.7 = 4.6.  However, we can't do that, because if that were to happen, we again will have a flat-line and not a triangle.  So whatever the third side may be, it must be less than 4.6, it can't be 4.6.

So no dice.

The value of x in the given figure of parallel lines is x = 0.89.

When two parallel lines are sliced by a transversal, alternating interior angles and alternate exterior angles result in the shape "Z".

From the figure we observe that according to alternate interior angle, the angle adjacent to x + 94 is 95x.

Thus, the two angles form a straight line.

The angle of a straight line is 180 degrees.

Thus,

x + 94 + 95x = 180

96x + 94 = 180

x = 0.89

Hence, the value of x in the given figure of parallel lines is x = 0.89.

a) U is subspace of R^3.

b) The set {(3, -2, 0), (0, 1/2, 1)} is a basis for U.

c) 2.

a) To show that U is a subspace of R^3, we need to verify the following three conditions:

i) The zero vector (0, 0, 0) is in U.

ii) U is closed under addition.

iii) U is closed under scalar multiplication.

i) The zero vector is in U since 0 + 2(0) - 3(0) = 0.

ii) Let (x1, y1, z1) and (x2, y2, z2) be two vectors in U. Then we have:

x1 + 2y1 - 3z1 = 0 (by definition of U)

x2 + 2y2 - 3z2 = 0 (by definition of U)

Adding these two equations, we get:

(x1 + x2) + 2(y1 + y2) - 3(z1 + z2) = 0

which shows that the sum (x1 + x2, y1 + y2, z1 + z2) is also in U. Therefore, U is closed under addition.

iii) Let (x, y, z) be a vector in U, and let c be a scalar. Then we have:

x + 2y - 3z = 0 (by definition of U)

Multiplying both sides of this equation by c, we get:

cx + 2cy - 3cz = 0

which shows that the vector (cx, cy, cz) is also in U. Therefore, U is closed under scalar multiplication.

Since U satisfies all three conditions, it is a subspace of R^3.

b) To find a basis for U, we can start by setting z = t (where t is an arbitrary parameter), and then solving for x and y in terms of t. From the equation x + 2y - 3z = 0, we have:

x = 3z - 2y

y = (x - 3z)/2

Substituting z = t into these equations, we get:

x = 3t - 2y

y = (x - 3t)/2

Now, we can express any vector in U as a linear combination of two vectors of the form (3, -2, 0) and (0, 1/2, 1), since:

(x, y, z) = x(3, -2, 0) + y(0, 1/2, 1) = (3x, -2x + (1/2)y, y + z)

Therefore, the set {(3, -2, 0), (0, 1/2, 1)} is a basis for U.

c) Since the basis for U has two elements, the dimension of U is 2.

To make a parallelogram a rhombus, make its sides equal, angles should be 90° and diagonals should be equal.

What is a parallelogram?

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side.

A parallelogram becomes a rhombus if and only if all four sides are congruent, which means they have the same length.

Therefore, to make the parallelogram QRST a rhombus, we need to ensure that all four sides are of equal length.

This can be achieved by satisfying any of the following conditions -

All four sides have the same length.

The diagonals of the parallelogram are perpendicular bisectors of each other.

In other words, they meet at right angles and divide each other into equal halves.

The diagonals of the parallelogram have equal length.

Therefore, if we can make sure that any of these three conditions are true for the parallelogram QRST, then we can make it a rhombus.

Using point-slope form, the coordinate of D(2, X) is 2 units away from point X(1, 1).

To find the coordinates of point D, we need to know the location of point X on the line YZ. We can use the slope-intercept form of the equation of a line to find the equation of the line passing through points Y and Z:

slope m = (y2 - y1) / (x2 - x1) = (0 - 2) / (3 - 2) = -2

Using the point-slope form of the equation of a line with point Y(2, 2) and slope m = -2:

y - y1 = m(x - x1)

y - 2 = -2(x - 2)

y - 2 = -2x + 4

y = -2x + 6

Now we can substitute x = 2 into the equation of the line to find the y-coordinate of point D:

y = -2x + 6

y = -2(2) + 6

y = 2

Therefore, the coordinates of point D are (2, 2).

So, D(2, 2) is the point that lies on line YZ and is 2 units away from point X(1, 1).

Cylinder B is taller which is 3.45 inches more than cylinder A.    

A cylinder is a three-dimensional geometric shape that consists of two parallel circular bases that are connected by a curved surface.

The formula for the volume of a cylinder is given by  

Where V is the volume of the cylinder, r is the radius of the circular base of the cylinder, and h is the height of the cylinder.

Here we have

Two cylinders have the same volume of 845π cubic inches.  

The radius of Cylinder A is 13 inches

Let 'h₁' be the height of th cylinder

By using the formula, V = π r² h₁

Volume of the cylinder A = π (13)² h₁ = 169πh₁

From the data, 169πh₁ = 845π

=> 169h₁ = 845

=> h₁ = 845/169

=> h₁ =  5  

The radius of Cylinder B is 10 inches.

Let h₂ be the height

Volume of the Cylinder B = π (10)² h₂ = 100πh₂  

From the data, 100πh₂ = 845π  

=> 100h₂ = 845

=> h₂ = 8.45

The difference between the heights of the two cylinders

= 8.45 inch - 5 inch = 3.45 inch  

Therefore,

Cylinder B is taller which is 3.45 inches more than cylinder A.

The solution (x, y, z) = (3, 5, -2) is verified to be true.

A 3x3 linear system whose solution is (x, y, z) = (3, 5, -2) is:

1x + 3y - z = 9

3x - 2y + 4z = 6

4x + y - z = 7

Verifying that (x, y, z) = (3, 5, -2) is the solution to this system:

1x + 3y - z = 9

1*3 + 3*5 - (-2) = 9

9 = 9, which is true.

3x - 2y + 4z = 6

3*3 - 2*5 + 4*(-2) = 6

6 = 6, which is true.

4x + y - z = 7

4*3 + 5 - (-2) = 7

7 = 7, which is true.

Therefore, the solution (x, y, z) = (3, 5, -2) is verified to be true.

Application of the following methods with the linear system:

In Gauss-Jordan Elimination, the matrix is reduced to reduced row-echelon form, with the right side becoming the solution. This can be done to the linear system:

1x + 3y - z = 9

3x - 2y + 4z = 6

4x + y - z = 7

By rearranging the equation and performing elimination, the system can be reduced to:

1 0 0 | 9

0 1 0 | 5

0 0 1 | -2

Therefore, the solution (x, y, z) = (3, 5, -2) is verified to be true.

In the Inverse Matrix Method, an inverse matrix is calculated and multiplied by the right side of the equation to get the solution. This can be done to the linear system:

1x + 3y - z = 9

3x - 2y + 4z = 6

4x + y - z = 7

By rearranging the equation and multiplying the inverse of the matrix with the right side of the equation, the solution can be found:

(1/17) * (1 -3 4 | 9)

(1/17) * (-3 2 -1 | 6)

(1/17) * (4 -1 1 | 7)

This yields the solution (x, y, z) = (3, 5, -2). Therefore, the solution (x, y, z) = (3, 5, -2) is verified to be true.

In Cramer's Rule, the determinants of the matrix are calculated and the solutions are found by dividing the determinant of the coefficient matrix by the determinants of the matrices that contain only one variable. This can be done to the linear system:

1x + 3y - z = 9

3x - 2y + 4z = 6

4x + y - z = 7

The determinant of the coefficient matrix is 17, and the determinants of the matrices that contain only one variable are the following:

x: 13

y: -7

z: 14

Dividing the determinants yields:

x = 13/17 = 0.76

y = -7/17 = -0.41

z = 14/17 = 0.82

Therefore, the solution (x, y, z) = (3, 5, -2) is verified to be true.

Formula explicitly = n² + 2 n, where n is a full number and the first 5 numbers of the sequence would be 4, 8, 12, 20, and 24.

Let 4,8,12,20,24 be the sequence's first five terms.

Let me define the terms explicit formula and recursive formula.

The generic formula to find any term in a series is known as the explicit formula.

Also, if we know the (n-1)th term of the series, we can use the recursive formula to find the nth term.

Thus, the sequence's explicit formula is,

Y equals 4 n, where n is any positive integer.

And this is the recursive formula.

Y = 4 (n-1), and we can find the nth term by using the (n-1)th term.

Initial term = 4 = 4 1

Term two = 8 = 4 2

Term three =12=43

Fourteenth term = 16 = 4 4

.....................

...........................

.................................

(n-1) th term =4 × (n-1)

nth term =4 × n

The universal and recursive formula is obtained by applying the straightforward technique of examining the first, second, and direction of the next term.

You stated that you did not desire a simpler sequence.

Think about the sequence's first five terms: 0, 3,8, 15, and 24.

Well stated formula =n2 + 2 n

Recursive equation: (n-1)

²+2(n-1)

If you examine the sequence, neither geometry nor arithmetic applies.

First term =0=0²+0×0

Second term =3=1+2=1²+2 × 1

Third term =8=4+4=2²+2×2

Fourth term =15=9+6=3²+2×3

Fifth term =24=16 +8=4²+2×4

In the explicit formula, n is a whole number and n²+2n.

Therefore, the formula explicitly = n² + 2 n, where n is a full number and the first 5 numbers of the sequence would be 4, 8, 12, 20, and 24.
