The clearance rules to solve the problem are the following:

The sign rules to solve the problem are the following:

Solving the equation we have:

-8. 5x – 3. 5x = –78

Two like signs add the values and keep the common sign.

-12x = -78

What is multiplying goes to the other side of the equality by dividing.

x = -78 / -12

x = 6.5

Substituting the (x) value in the equation we can check the answer and we get:

-8. 5x – 3. 5x = –78

-8.5(6.5) - 3.5(6.5) = -78

-55.25 - 22.75 = -78

- 78 = - 78

Answer:

a₁ = 7

a\(_{n}\) = -3 ⋅ a\(_(n-1)\), for n > 1

Step-by-step explanation:

Do you want to know how to write a recursive formula for a_n, the n^th term of the sequence: 7, -21, 63, -189...? Well, it's easy as pie! Just follow these simple steps:

1. Find the common ratio of the sequence. This is the number that you multiply each term by to get the next term. In this case, it's -3. You can check by dividing any term by the previous term. For example, -21 / 7 = -3, 63 / -21 = -3, and so on.

2. Write the formula for a\(_{n}\) using the common ratio and the previous term. The formula is a\(_{n}\) = -3  ⋅ a\(_(n-1)\)), where n is any positive integer greater than 1. This means that to find any term in the sequence, you just multiply the previous term by -3.

3. Write the formula for a₁, the first term of the sequence. This is the starting point of the recursion. In this case, it's 7. You can find it by looking at the first term in the sequence or by plugging in n = 1 into the formula for a\(_{n}\)  .

4. Voila! You have written a recursive formula for a\(_{n}\) . The formula is:

a₁ = 7

a\(_{n}\) = -3 ⋅ a\(_(n-1)\), for n > 1

Congratulations! You are now a master of recursion! Give yourself a pat on the back and celebrate with some pi!

Answer:

149 is the 47th term in the given sequence.

Step-by-step explanation:

An = A1 + (n-1)d

In this problem, An is represented as A47, or the term we are looking to find,

A1 is the first number in the sequence, so in this case, it would be 11,

n is the term that is attached to An, in this case, it would be 47,

d is the common difference, or what number can I add or subtract to get the other number and all other numbers in the sequence, for this case it would be 3. (11+3=14, 14+3=17, 17+3=20)

Now, we plug in all numbers, and it would look like

11+(47-1)3

11+(46)3

11+138=149

The arrival rate (λ) is approximately 0.5 jobs per hour, and the service rate (μ) is approximately 0.3125 jobs per hour.

The operating characteristics are approximately:
Lq = 1.3333
L = 2.1333
Wq = 2.6667
W = 5.3333

(a) To find the arrival rate (λ) and service rate (μ) in jobs per hour, we need to convert the given rates from jobs per day to jobs per hour.

Given:
Arrival rate: 2 jobs per 8-hour day
Mean repair time (service time): 3.2 hours

To convert the arrival rate to jobs per hour:
λ = (2 jobs / 8 hours) * (1 hour / 1/8 day)
λ = 0.5 jobs per hour

To find the service rate (μ), we can use the reciprocal of the mean repair time:
μ = 1 / (mean repair time)
μ = 1 / 3.2
μ ≈ 0.3125 jobs per hour

(b) Operating characteristics:
Lq: Average number of jobs in the queue
L: Average number of jobs in the system (queue + being served)
Wq: Average time a job spends in the queue
W: Average time a job spends in the system (queue + service time)

To calculate these operating characteristics, we can use the formulas for a single-server queue with exponential arrival and service times:

Lq = λ^2 / (μ * (μ - λ))
L = λ / (μ - λ)
Wq = Lq / λ
W = Wq + (1 / μ)

Plugging in the values:

Lq = (0.5^2) / (0.3125 * (0.3125 - 0.5))
L ≈ 0.25 / 0.1172
Wq = Lq / 0.5
W = Wq + (1 / 0.3125)

Evaluating the expressions:

Lq ≈ 1.3333
L ≈ 2.1333
Wq ≈ 2.6667
W ≈ 5.3333

The website which is cheaper for Caroline to buy the spice mix is French website.

Given data ,

Let's calculate the total cost for Caroline from both websites and determine which one is cheaper.

British website:

Price for 100 g = (£0.90 / 25 g) * 100 g = £3.60

Since the British website offers free delivery, the total cost remains £3.60.

French website:

Price for 100 g = (€1.20 / 50 g) * 100 g = €2.40

Delivery cost = €0.80

On simplifying the equation , we get

To convert the price and delivery cost to pounds, we'll use the conversion rate: €1 = £0.85.

Price in pounds = €2.40 * £0.85 = £2.04

Delivery cost in pounds = €0.80 * £0.85 = £0.68

Total cost = Price in pounds + Delivery cost = £2.04 + £0.68 = £2.72

Comparing the total costs:

British website: £3.60

French website: £2.72

Hence , Caroline would pay £2.72 for the spice mix from the cheaper website, which is the French website.

A graph is a function if it passes the vertical line test (in other words, every vertical line that can be drawn intersects the graph at no more than one point).

This is because for a function, each input must map onto no more than one output.

By mathematical induction, T(n) = nlog(n) for all n that are exact powers of 2.

We will prove by mathematical induction that T(n) = nlog(n) for all n that are exact powers of 2.

Base case: For n = 2, we have T(2) = 2 as given.

Inductive hypothesis: Assume that T(\(2^k\)) = \(2^k\) × log(\(2^k\)) for some positive integer k.

Inductive step: We need to show that T(\(2^{(k+1)}\)) = \(2^{(k+1)}\) × log(\(2^{(k+1)}\)).

Using the recurrence relation, we have:

T(\(2^{(k+1)}\)) = 2T(\(2^k\)) + \(2^{(k+1)}\)

Substituting T(\(2^k\)) = \(2^k\) × log(\(2^k\)) from the inductive hypothesis, we get:

T(\(2^{(k+1)}\)) = 2(\(2^k\) × log(\(2^k\))) + \(2^{(k+1)}\)

      = \(2^{(k+1)}\) × k × log(2) + \(2^{(k+1)}\)

      = \(2^{(k+1)}\) × (k+1)

      = \(2^{(k+1)}\) × log(\(2^{(k+1)}\))

For every n that are precise powers of 2, T(n) = nlog(n) is the result of mathematical induction.

The postfix expression of "7+5-3*2(6*7)/4" is "7 5 + 3 2 * 6 7 * 2 * - 4 /". Evaluating the postfix expression gives the result of the expression. The prefix expression for the given infix expression is "/ - + 7 5 * 3 * 2 ( * 6 7 ) 4".

To convert the infix expression "7+5-3*2(6*7)/4" into postfix expression, we follow the rules of operator precedence and associativity. The postfix expression is obtained by placing operators after their operands.

The postfix expression for the given infix expression is:

"7 5 + 3 2 * 6 7 * 2 * - 4 /"

To evaluate the postfix expression, we use a stack data structure. We scan the postfix expression from left to right and perform the corresponding operations.

Starting with an empty stack, we encounter the operands "7" and "5". We push them onto the stack. Then we encounter the operator "+", so we pop the last two operands from the stack (5 and 7), perform the addition operation (7 + 5 = 12), and push the result back onto the stack.

We continue this process for the remaining operators and operands in the postfix expression. Finally, after evaluating the entire expression, the result left on the stack is the final answer.

To convert the infix expression into prefix expression, we follow similar rules but scan the expression from right to left. The prefix expression is obtained by placing operators before their operands.

Note that the probability that a person selected at random would test positive for this disease is 0.06894.

We are given that the detection of a certain disease gives a positive result 5 percent of the time for people who do not have the disease.

This means:
P(positive results | do not have disease) = 0.05

We also know that the test gives a negative result 0.3 percent of the time for people who have the disease. What this means is that the test gives a positive result 99.7 percent of the time for people who have the disease.

Thus,
P(positive results |  have disease) = 0.997;

Then, we know that

large-scale studies have shown that the disease occurs in about 2 percent of the population. That is P(have disease) = 0.02, P(do not have disease) = 0.98

Thus, the probability that a person selected randomly would test positive is:
P(positive results) = P( Positive results ∩ have disease) + P(Positive results ∩ do not have disease)

= P(have disease) P (Positve results | have disease) + P(do not have disease)  P(Positive results) | do not have disease)

= (0.02 x 0.0997) + (0.98 x 0.05)
= 0.06894

Commission = (Rate of commission) x (Total sales amount)

= 7.25% x (9 x $60)

= $39.15

For Helen:

Commission = (Rate of commission) x (Total sales amount)

= 7.50% x (12 x $50)

= $45.00

For Reid:

Commission = (Rate of commission) x (Total sales amount)

= 8.25% x (10 x $40)

= $33.00

For Sidney:

Commission = (Rate of commission) x (Total sales amount)

= 7.75% x (6 x $90)

The expression (8v10) (815) simplifies to 6520v10 solved by using indicated multiplication.

To simplify the expression (8v10) (815), we need to perform the indicated multiplication.

First, let's simplify the expression within the first parentheses, (8v10):

v represents the square root (√) symbol. So, we have:

8v10 = 8√10

Now, let's simplify the expression within the second parentheses, (815):

815 is already in its simplest form.

Next, we multiply the two simplified expressions together:

(8√10) (815) = 8√10 × 815

To calculate this product, we multiply the numbers outside the square root and then multiply the numbers inside the square root:

8 × 815 = 6520

√10 remains as it is.

Finally, combining the results, we have the simplified form:

(8v10) (815) = 6520v10

Given that Treatment A B C

p-value 0.075

Conclusion These data do not provide evidence of a difference between treatments.

The F-ratio for the new data will be lower than the F-ratio for the original data. This is because the difference between the means of the three treatments has been reduced. When the difference between the means is smaller, the F-ratio will be smaller.

The F-ratio for the new data is not significant, which means that there is not enough evidence to conclude that there is a difference between the treatments. The p-value of 0.075 is greater than the alpha level of 0.05, so we cannot reject the null hypothesis.

Kevin's rate is 6 miles per hour and the rate of the current is 4 miles per hour.

What is rate?

Let's call Kevin's rate (or speed) "k" and the rate of the current "c".

When Kevin is traveling downstream, his effective speed is the sum of his own speed and the speed of the current, so his effective speed can be written as:

k + c

We know that he travels 30 miles downstream in 3 hours, so we can write an equation:

30 = 3(k + c)

When Kevin is traveling upstream (against the current), his effective speed is the difference between his own speed and the speed of the current, so his effective speed can be written as:

k - c

We know that the return trip took 15 hours, so we can write another equation:

30 = 15(k - c)

Now we have two equations with two unknowns, which we can solve as a system of linear equations.

First, we can simplify the second equation by dividing both sides by 15:

2 = k - c

Now we have a system of two equations:

30 = 3(k + c)

2 = k - c

We can solve this system using substitution or elimination. Let's use substitution:

From the second equation, we can solve for k:

k = 2 + c

Substitute this expression for k into the first equation:

30 = 3(2 + c + c)

Simplify:

30 = 6 + 6c

Subtract 6 from both sides:

24 = 6c

Divide by 6:

c = 4

Now we can substitute this value of c into either equation to solve for k. Let's use the second equation:

2 = k - c

Substitute c = 4:

2 = k - 4

Add 4 to both sides:

k = 6

So Kevin's rate is 6 miles per hour and the rate of the current is 4 miles per hour.
