The value of the absolute percent error for week 3 is 25.00%.

To calculate the absolute percent error for week 3, we need to find the absolute difference between the forecasted value and the actual value, and then divide it by the actual value. Finally, we multiply the result by 100 to convert it to a percentage.

To find the absolute percent error for week 3, we'll use the formula:

Absolute Percent Error = |(Actual Value - Forecasted Value) / Actual Value| * 100

For week 3:

Actual Value = 4.00

Forecasted Value = 3.00

Absolute Percent Error = |(4.00 - 3.00) / 4.00| * 100

= |1.00 / 4.00| * 100

= 0.25 * 100

= 25.00

Therefore,For week three, the absolute percent error value is 25.00%.

The perimeter of The perimeter of triangle ABC is 18 units. ABC is 18 units.

To find the perimeter of triangle ABC, we need to calculate the lengths of its sides and then sum them.

Using the distance formula, we can find the lengths of the sides:

AB = \(√[(-4-0)^2 + (1-(-2))^2] = √[16 + 9] = √25\) = 5 units

BC = \(√[(0-4)^2 + (-2-1)^2] = √[16 + 9] = √25\)= 5 units

CA = \(√[(4-(-4))^2 + (1-1)^2] = √[64 + 0] = √64\) = 8 units

Now, we can sum the lengths of the sides to find the perimeter:

Perimeter = AB + BC + CA = 5 + 5 + 8 = 18 units

According to the model, 18% of gross domestic product will go toward health care in the year 2026.

To find the year when 18% of gross domestic product (GDP) will go toward health care according to the given model, we need to solve the equation:

f(x) = 18

where f(x) represents the percentage of GDP going toward health care x years after 2006.

Given the model f(x) = 1.4 ln(x) + 13.8, we can substitute 18 for f(x):

1.4 ln(x) + 13.8 = 18

Subtracting 13.8 from both sides:

1.4 ln(x) = 4.2

Dividing both sides by 1.4:

ln(x) = 3

To solve for x, we can exponentiate both sides using the base e (natural logarithm):

e^(ln(x)) = e^3

x = e^3

Using a calculator, the approximate value of e^3 is 20.0855.

Therefore, according to the model, 18% of GDP will go toward health care in the year 2006 + x = 2006 + 20.0855 ≈ 2026 (rounded to the nearest year).

The probability of exactly 6 customers entering the mall in a 1-hour period is 0.0127 (approx). The probability of 0 customers entering the mall in a 20-minute period is 0.0067 (approx).

Given data: shoppers enter a mall at the rate of 15 per hour. We need to find the probabilities of different events. Explanation: Exactly 6 customers enter mall in a 1-hour period

P(X = 6) = (e^-15 * 15^6) / 6! = 0.0127 (approx)

Therefore, the probability of exactly 6 customers entering the mall in a 1-hour period is 0.0127 (approx).

0 customers enter the mall in a 20-minute period. Here, the time is given in minutes and the rate is given in an hour. Hence, we need to first convert the rate into a 20-minute period. So, the rate of customers entering the mall in 20 minutes = 15/3 = 5.Now,

P(X = 0) = e^-5 = 0.0067 (approx)

Therefore, the probability of 0 customers entering the mall in a 20-minute period is 0.0067 (approx).

1 customer enters the mall in a 20-minute period. The rate of customers entering the mall in 20 minutes is already calculated as 5.

P(X = 1) = (e^-5 * 5^1) / 1! = 0.0337 (approx)

Therefore, the probability of 1 customer entering the mall in a 20-minute period is 0.0337 (approx).

At least 2 customers will enter the mall in a 20-minute period. Here, we need to find the probability of 2 or more customers entering the mall in 20 minutes.

P(X ≥ 2) = 1 - P(X ≤ 1)P(X ≤ 1) = P(X = 0) + P(X = 1) = 0.0067 + 0.0337 = 0.0404

Now, P(X ≥ 2) = 1 - P(X ≤ 1) = 1 - 0.0404 = 0.9596

Therefore, the probability of at least 2 customers entering the mall in a 20-minute period is 0.9596.5) At most, 1 customer will enter the mall in a 20-minute period. Here, we need to find the probability of 0 or 1 customers entering the mall in 20 minutes.

P(X ≤ 1) = P(X = 0) + P(X = 1) = 0.0067 + 0.0337 = 0.0404Therefore, the probability of at most 1 customer entering the mall in a 20-minute period is 0.0404.

To summarize, the probabilities of the given events are:

P(X = 6) = 0.0127 (approx)

P(X = 0) = 0.0067 (approx)

P(X = 1) = 0.0337 (approx)

P(X ≥ 2) = 0.9596 (approx)

P(X ≤ 1) = 0.0404 (approx)

Answer:

The order of the matrix D^T × (BE) is 2 × 4

Step-by-step explanation:

In the multiplication of matrix, the number of columns in the first matrix must be equal to the number of rows of the second matrix. The resulting matrix from the product will have the same number of rows as the first matrix and the same number of column as the second matrix. For example, given Matrix A of order (m × n) and Matrix Z of order ( n × k), the product of the two matrices will give a matrix ( say Y) of order (m × k).

AZ = Y

(m x n)(n x k) = (m x k)

Now, From the question,

The order of Matrix B is 4 × 5,

the order of the matrix D is 4 × 2

and the order of the matrix E is 5 × 4.

To determine the order of the matrix D^T × (BE)

First, will find the order of (BE)

Order of BE = (4 × 5) (5 × 4)

Order of BE = (4 × 4)

Hence, the order of matrix (BE) is 4 × 4.

Now, we will determine the order of matrix D^T

D^T means the transpose of matrix D.

The transpose of a matrix is defined as a new matrix whose rows are the columns of the original matrix and the columns of the new matrix are the rows of the original matrix. This means given Matrix A of order (m × n), the transpose of Matrix A (A^T) will have an order of (n × m).

The order of the matrix D is 4 × 2

Hence, the order of the transpose of matrix D (D^T) will be 2 × 4

Now, the order of the matrix D^T × (BE) will be

Order of the matrix D^T × (BE) = (2 × 4) × (4 × 4)

Order of the matrix D^T × (BE) = 2 × 4

Hence, the order of the matrix D^T × (BE) is 2 × 4.

Step-by-step explanation:

The travel time x is 41.162 min such that 17.36% of the 60 days have a travel time that is at least x.

We have to determine the travel time such that 17.36% of the 60 days have a travel time that is at least.

Total work days to work = 60 days

The travel mean time = 35.6

Standard deviation = 10.3

For normal distribution,

P(X < A) = P(Z < (A - mean)/standard deviation)

P(X > x) = 0.2946

P(X < x) = 1 - 0.2946 = 0.7054

P(Z < (x - 35.6)/10.3) = 0.7054

Take the z value that corresponds to 0.7054 in the table of the standard normal distribution.

(x - 35.6)/10.3 = 0.54

Answer:

0.9375 feet of trim

Step-by-step explanation:

Step 1

We find the total number of inches used

We are told : She needs a piece of trim that is 8 1/8 inches long for the sleeves and a piece that is 40 5/8 inches long for the hem.

Hence, the total = (8 1/8 + 40 5/8)inches = 48 3/4

= 48.75 inches

Step 2

We convert to feet

1 inch = 0.0833333 feet

48.75 inches = x

Cross Multiply = 48.75 × 0.00833333 feet

= 4.0625 feet

Hence, she would use 4.0625 feet of ribbon

If the package contains 5 feet of trim, how much trim will she have left after making the costume.

This is calculated as:

5 feet - 4.0625 feet

= 0.9375 feet of trim

If a calculator is sold for R120 and the original selling price is Increased in a ratio of 5:3, the new price of the calculator will be R200.

Let the original selling price of the calculator be x.The price it is sold for is R120.

Then 120/x = 5/3x = (3 × 120)/5x = 72

New price of the calculator = (5/3) × 72= 120Therefore, the new price of the calculator is R200.

To determine the new price of the calculator after an increase in the ratio of 5:3, we can use the following steps:

Calculate the multiplier for the ratio increase:

multiplier = (new ratio) / (old ratio)

multiplier = 5/3

Multiply the original selling price by the multiplier to get the new price:

new price = original selling price * multiplier

new price = R120.0 * (5/3)

new price = 200.0 rupees.

The infinite geometric series 1 - 1/5 + 1/25 - 1/125 + ... is convergent and the sum of this infinite geometric series is 5/6.

To determine whether the infinite geometric series is convergent or divergent, and to find its sum if convergent, we'll consider the given series: 1 - 1/5 + 1/25 - 1/125 + ...

Step 1: Identify the common ratio (r).
In a geometric series, each term is a constant multiple of the previous term.

In this case, we can see that the common ratio is -1/5 because each term is obtained by multiplying the previous term by -1/5.

Step 2: Determine convergence or divergence.
An infinite geometric series converges if the absolute value of the common ratio (|r|) is less than 1, and diverges if |r| is greater than or equal to 1.

Since |-1/5| = 1/5 < 1, the series is convergent.

Step 3: Calculate the sum.
For a convergent geometric series, the sum can be found using the formula:
Sum = a / (1 - r)
where 'a' is the first term and 'r' is the common ratio.

In this case, a = 1 and r = -1/5, so:

Sum = 1 / (1 - (-1/5))
Sum = 1 / (1 + 1/5)
Sum = 1 / (6/5)
Sum = 5/6

Therefore, the sum of the infinite geometric series 1 - 1/5 + 1/25 - 1/125 + ... is 5/6.

Answer:

The confidence interval is (657.18, 661.02)

or , CI = 659.1 ± 1.922

Step-by-step explanation:

We have to ind the 95% confidence interval,

Mean = Y = 659.1

Standard Deviation = s(Y) = 19.9

Confidence level = 95%

Alpha value = (1 - 0.95)/2

Alpha value = 0.025

So,

This gives a z value of,

z = - 1.96

Now, there are 412 districts so, n = 412

so,

The upper limit is,

Upper limit =  UL = Y + z(s(Y))/sqrt(n)

\(UL = Upper limit = Y + z(s(Y))/\sqrt{n}\\UL = 659.1 + (1.96)(19.9)/|sqrt(412)\\UL = 661.02\)

Lower limit is,

LL = Y - z(s(Y))/sqrt(n)

\(LL = 659.1 - (1.96)(19.9)/\sqrt{412}\\LL = 657.18\)

Hence the confidence interval is (657.18, 661.02)

where, T is the total cost, b is the number of bath towels, and w is the number of wash cloths.

Her budget is $85.

To find:

The constraints, so that she can order a maximum of washcloths or bath towels.

Solution:

We have,

\(T=6b+2w\)

Her budget is $85. So, total cost is less than or equal to 85.

\(6b+2w\leq 85\)       ...(i)

For maximum number of bath towels, the number of wash cloths is 0.

\(6b+2(0)\leq 85\)

\(6b\leq 85\)

Divide both sides by 6.

\(b\leq \dfrac{85}{6}\)

\(b\leq 14.167\)

For maximum number of wash cloths, the number of bath towels is 0.

\(6(0)+2w\leq 85\)

\(2w\leq 85\)

Divide both sides by 2.

\(w\leq \dfrac{85}{2}\)

\(w\leq 42.5\)

Therefore, the required constraints for maximum of washcloths or bath towels are \(w\leq 42.5\) and \(b\leq 14.167\) respectively.
