Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

The expression (x² + 3) / (x-3)(x-1) is the simplified form of the given expression. which is the correct answer would be an option (B).

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given below as:

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

To simplify the expression, we can first combine the terms that have a common denominator:

(x-3)²+ 6(x-1) / (x-3)(x-1)

We can simplify the expression further by using the fact that

(x² + 9 - 6x + 6x - 6) / (x-3)(x-1)

Combine the likewise terms and apply the arithmetic operation,

(x² + 3) / (x-3)(x-1)

The solution for question a is -2.00. The solution for question b is  0.6687. The solution for question c is 10 students. We can show the working in the following manner.

a. What is the probability of completing the exam in one hour or less (to 4 decimals)?

To answer this question, we need to convert the time of one hour (60 minutes) to a z-score using the mean and standard deviation provided. We have:

z = (60 - 80) / 10 = -2.00

Using a standard normal distribution table or calculator, we can find that the probability of completing the exam in one hour or less is approximately 0.0228, rounded to 4 decimal places.

b. What is the probability that a student will complete the exam in more than 60 minutes but less than 75 minutes (to 4 decimals)?

To answer this question, we need to find the probability of completing the exam in less than 75 minutes and subtract the probability of completing the exam in less than 60 minutes. We have:

z1 = (60 - 80) / 10 = -2.00

z2 = (75 - 80) / 10 = -0.50

Using a standard normal distribution table or calculator, we can find that the probability of completing the exam in less than 75 minutes is approximately 0.6915 and the probability of completing the exam in less than 60 minutes is approximately 0.0228, as calculated in part a.

So, the probability of completing the exam in more than 60 minutes but less than 75 minutes is approximately:

0.6915 - 0.0228 = 0.6687, rounded to 4 decimal places.

c. Assume that the class has 60 students and that the examination period is 90 minutes in length. How many students do you expect will be unable to complete the exam in the allotted time (to the next whole number)?

To answer this question, we need to find the number of students whose exam time is greater than 90 minutes, which is the maximum time allowed. We can use the normal distribution with the given mean and standard deviation to calculate this.

First, we need to find the z-score corresponding to a time of 90 minutes:

z = (90 - 80) / 10 = 1.00

Using a standard normal distribution table or calculator, we can find that the probability of completing the exam in more than 90 minutes is approximately 0.1587.

Therefore, the expected number of students who will be unable to complete the exam in the allotted time is:

60 x 0.1587 = 9.52, which rounds up to 10 students (to the next whole number).

The given statement states that for positive integers n, M, d, and q > 1 (with 1 ≤ d ≤ n), if (M-1)q^(n-d)(q-1) < q^n, then there exists a q-ary (n, M)-code with a minimum distance of at least d.

To prove this, we can use the Singleton bound. The Singleton bound states that for any q-ary (n, M)-code, the minimum distance d satisfies the inequality d ≤ n - (M-1)q^(n-d)(q-1).

Given that (M-1)q^(n-d)(q-1) < q^n, we can rewrite it as q^n - (M-1)q^(n-d)(q-1) > 0.

Substituting this inequality into the Singleton bound inequality, we have d ≤ n - (M-1)q^(n-d)(q-1) < n - q^n + (M-1)q^(n-d)(q-1).

Since q^n - (M-1)q^(n-d)(q-1) > 0, we can simplify the inequality further to d < n - q^n + (M-1)q^(n-d)(q-1).

Therefore, we have shown that there exists a q-ary (n, M)-code with a minimum distance of at least d.

The value of x in the equilateral triangle in radical form is  \(\frac{10\sqrt{3} }{3}\).

The figure in the image is a right an equilateral triangle, meaning all its three sides are equal.

Since all its three sides are equal, each sides is x.

Meaning half of each side is x/2.

Dividing the equilateral triangle into two wqual halves forms a right triangle:

Hypotenuse = x

Leg 1 = 5

Leg 2 = x/2

Using pythagorean theorem, we can solve for x:

( hypotenuse )² = ( leg 1 )² + (leg 2 )²

x² = 5² + ( x/2 )²

x² = 5² + ( x/2 )²

x² = 5² + x²/2²

x² = 25 + x²/4

x² - x²/4 = 25

3x²/4 = 25

3x² = 25 × 4

3x² = 100

x² = 100/3

x = √(100/3)

\(x = \frac{10\sqrt{3} }{3}\)

The combination of functions (f-g)(x) involves subtracting the function g(x) from the function f(x). The difference between the functions f(x) and g(x) at x = 2 is -1.

To find (f-g)(x), we subtract g(x) from f(x). Given f(x) = 2x + 1 and g(x) =\(x^2 + 2x - 1\), we can write (f-g)(x) as f(x) - g(x).

Substituting the functions, we have (f-g)(x) = (2x + 1) - \((x^2 + 2x - 1)\). Simplifying this expression, we combine like terms:

(f-g)(x) =\(2x + 1 - x^2 - 2x + 1\)

=\(-x^2 + 3\)

To evaluate (f-g)(2), we substitute x = 2 into the expression:

(f-g)(2) = -(2)^2 + 3

= -4 + 3

The sum  of the present age of Juan and Maria is 32 years.

Step-by-step explanation:

Maria's age is three times Juan's age. In 7 years the sum of their ages will be 46 years. The sum of the current ages of Juan and Maria is

Let the Juan's present age is p.

Maria's present age is 3 p.

After 7 years,

Juan's age = p + 7

Maria's age = 3 p + 7

According to the question

p + 7 + 3 p + 7 = 46

4 p + 14 = 46

4 p = 32

p = 8

So, the present age of Juan is 8 years and Maria is 24 years, the sum is 8 + 24 = 32.  

Therefore, there are 8^13 ways for Felicity to make her candy bar selection at the grocery store.

To calculate the number of ways Felicity can make her selection, we need to consider that she can choose from the available varieties of candy bars. Since there are 8 varieties in total, she has 8 options for the first candy bar. Similarly, for the second candy bar, she still has 8 options since she can choose from the same varieties again. This process continues for all 13 candy bars.

To find the total number of ways, we multiply the number of options for each candy bar together. Since each candy bar is chosen independently, the total number of ways Felicity can make her selection is calculated as 8 multiplied by itself 13 times (8^13). This yields a large number of possible combinations, representing the various ways she can choose candy bars from the available varieties.

To calculate Evan's AGI (Adjusted Gross Income) and taxable income if he files as a single taxpayer, we need to consider his income and deductible expenses.

Calculate Evan's total income:
  - Salary: $73,650
  - Part-time hourly pay: $700

  Total income = Salary + Part-time pay = $73,650 + $700 = $74,350

Deductible expenses:
  - Moving expenses: $1,200
  - Student loan interest: $2,890
  - Uniform cost: $1,490
  - Cash contribution: $1,345

  Total deductible expenses = $1,200 + $2,890 + $1,490 + $1,345 = $6,925

Calculate AGI:
  AGI = Total income - Total deductible expenses
  AGI = $74,350 - $6,925 = $67,425

Evan's taxable income is equal to his AGI since there were no other deductions mentioned in the question.

Evan's AGI is $67,425 and his taxable income is $54,875 if he files as a single taxpayer.

We have,

Income:

Salary: $73,650

Part-time work pay: $700

Total income: $73,650 + $700 = $74,350

Deductible Expenses:

Cost of moving possessions: $1,200

(This deduction applies if the move meets certain distance and time requirements. Since the move was 125 miles away, it meets the distance requirement.)

Interest paid on student loans: $2,890

Cost of purchasing a delivery uniform: $1,490

Cash contribution to State University deliveryman program: $1,345

Total deductible expenses:

$1,200 + $2,890 + $1,490 + $1,345

= $6,925

Now we can calculate Evan's AGI and taxable income:

AGI (Adjusted Gross Income)

= Total income - Deductible expenses

AGI = $74,350 - $6,925 = $67,425

Taxable Income = AGI - Standard Deduction

For a single filer in 2022, the standard deduction is $12,550.

Taxable Income = $67,425 - $12,550 = $54,875
