Therefore by increasing  [tex]\alpha[/tex] smoothing characteristics we can achieve minimum MSE which is good for forecasting in exponential smoothing.

Therefore the pattern of the data is a horizontal pattern in time series.

a) To calculate a two-week moving average, we first need to calculate the average of the first two weeks:

[tex]MA_{1}=\frac{24+13}{2}=18.5[/tex]

Then we can calculate the moving average for the second week as follows:

[tex]MA_{2}=\frac{13+20}{2}=16.5[/tex]

Similarly, we can calculate the moving averages for the rest of the weeks:

3 20 16.5

4 12 16.0

5 19 15.5

6 23 21.0

7 15 19.0

The forecast for the fourth week is the moving average for the second week (16.5), and the forecast for the fifth week is the moving average for the third week (16.0), and so on. The forecast error is the difference between the forecast value and the actual value.

Week Value Two-Week Moving Average Forecast Forecast Error

5 19 15.5 16.0 3.0

6 23 21.0 15.5 7.5

7 15 19.0 21.0 -6.0

The mean squared error (MSE) is the average of the squared forecast errors:

MSE= [tex]\frac{(-4.5)^{2}+3^{2}+7.5^{2}+(-6)^{2}}{4}=33.375[/tex]

The forecast for the eighth week is the moving average for the seventh week (19.0).

b) To calculate a three-week moving average, we first need to calculate the average of the first three weeks:

[tex]MA_{2}=\frac{24+13+20}{3}=19.0[/tex]

Then we can calculate the moving average for the third week as follows:

[tex]MA_{3}=\frac{13+20+12}{3}=15.0[/tex]

Similarly, we can calculate the moving averages for the rest of the weeks:

The polynomial of best fit for this set of points is p(x) = a0 + a1x + a2x^2, where a0, a1, and a2 are the coefficients that minimize the sum of the squared differences between the actual y-values and the predicted y-values of the polynomial.

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.

So, the polynomial of best fit for this set of points is p(x) = a0 + a1x + a2x^2, where a0, a1, and a2 are the coefficients that minimize the sum of the squared differences between the actual y-values and the predicted y-values of the polynomial.

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.

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.

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. Using this conversion, your weight would be approximately 14.5 st (rounded to one decimal place).

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).

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°

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

The correct answer is (i) and (ii). Both of the sets are subspaces of R3 because they satisfy the three criteria of a subspace. The first set, {(x,y,z)| z = (x+y)2}, is a set of all triplets (x,y,z) such that z = (x+y)2. The second set, {(x,y,z)| x=10z}, is a set of all triplets (x,y,z) such that x = 10z. Neither of the other choices are correct.

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.

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

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 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%.

Carter will have to work about 33 hours in order to save $300.

To find out how many hours Carter will have to work in order to save $300, we can use the following steps:

1. First, we need to determine how much Carter saves per hour. Since he saves (3)/(5) of his earnings, we can multiply his hourly wage by (3)/(5) to find out how much he saves per hour:

$15.25 * (3)/(5) = $9.15

2. Next, we need to determine how many hours Carter will have to work in order to save $300. To do this, we can divide $300 by the amount he saves per hour:

$300 / $9.15 = 32.79 hours

3. Since Carter can't work a fraction of an hour, we'll round up to the nearest whole hour:

33 hours

While waiting for your sister to finish her bungee jump, you decide to figure out how tall the platform she is jumping off is. The height of the platform is 106ft.

We can use trigonometry to find the height of the platform.

Let's h represent the height of the platform. The angle between the ground and our line of sight to the top of the platform is 90 - 62 = 28 degrees.

The distance between our position and the top of the platform is the hypotenuse of a right triangle with one leg of length 200 feet and an angle of 28 degrees. We can use the tangent function to find the height of the platform:

tan(28) = h/200

To solve for h, we can multiply both sides by 200:

h = 200 * tan(28)

h = 200 * 0.532

h = 106 feet

Therefore, the platform is approximately 106 feet tall.

The simplified expression is [tex](z^{(16))}(y^{(12))}/(100663296)(x^{(8))}[/tex].

To simplify the expression ((4x^(2)z^(-4))/(20y^(-3)))^(-4) using the properties of exponents, we need to follow the steps below:

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:

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

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:

(z^(16))(y^(12))/(16^(2))(x^(8))(2^(8))(5^(8))

6. Now, we can combine the terms with the same base to get our final answer:

(z^(16))(y^(12))/(256)(x^(8))(256)(390625)

7. Our final answer is:

(z^(16))(y^(12))/(100663296)(x^(8))

Therefore, the simplified expression is (z^(16))(y^(12))/(100663296)(x^(8)).

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

Therefore, the aspirin level will be less than 10 milligrams after approximately 45.06 hours.
