Find a recurrence relation for the number of n digit quaternary (0, 1, 2, 3) sequences with at least one 1 and the first 1 occurring before the first 0 (possibly no 0s).

Answers

Answer 1

The recurrence relation for the number of n-digit quaternary sequences with at least one 1 and the first 1 occurring before the first 0 is:

\(A_n = 2 * A_{n-1}\)

Let's denote the number of n-digit quaternary sequences satisfying the given conditions as \(A_n\). We can establish a recurrence relation for A_n based on the position of the first digit in the sequence.

Consider the possible cases:

1. Case 1: The first digit is 1.

  In this case, the remaining n-1 digits can be any valid (n-1)-digit quaternary sequence that satisfies the given conditions.

Since the first 1 has already been placed, the remaining sequence can have any combination of digits 1, 2, and 3. Hence, the number of such sequences is \(A_{n-1}\).

2. Case 2: The first digit is not 1.

  If the first digit is not 1, it must be 2 or 3 (as per the given conditions). In this case, the remaining n-1 digits can be any valid (n-1)-digit quaternary sequence satisfying the given conditions, without any restriction on the placement of 0s and 1s.

Hence, the number of such sequences is \(A_{n-1}\).

Therefore, the recurrence relation for the number of n-digit quaternary sequences with at least one 1 and the first 1 occurring before the first 0 is:

\(A_n = 2 * A_{n-1}\)

This recurrence relation states that the number of n-digit sequences satisfying the given conditions is twice the number of (n-1)-digit sequences satisfying the same conditions.

We also have the base case A₁ = 1, as there is only one valid 1-digit quaternary sequence that satisfies the given conditions, which is "1".

Using this recurrence relation, you can compute the number of n-digit quaternary sequences with the specified conditions for any given value of n.

Answer:

youngest=115

middle=150

elder=230

Step-by-step explanation:

let the youngest be x

the middle will be x+35

the oldest will be 2x

x+x+35+2x=495

4x+35=495

4x=495-35

4x=460

x=115

since the youngest is x,the money he will receive is $115.

the middle will be x+35 which is equal to 115+35=$150.

lastly the oldest will be 2x which is equal to 2×115=$230.

Answer:

Defined variables:

Y - amount the youngest son gets

M - amount the middle son gets

O - amount the oldest son gets

Y got $115

M got $150

O got $230

Step by Step explaination:

If Y is the youngest, then the middle son, M = Y + $35 since the middle child gets $35 more than the youngest gets. The oldest son, O = 2Y since it’s twice the amount the youngest gets.

If you add each of those up, the equation you get is 2Y + (Y+$35) + Y = $495. Now you can solve for Y, the youngest son.

2Y + (Y+$35) + Y = $495

4Y + $35 = $495

4Y = $460

Y = $115

If Y gets $115 and M gets $35 more, M gets $150.

If Y gets $115 and O gets twice that amount, O gets $230.

To double check my work add 230 + 115 + 150. This equals $495. Hope this helps!

So, the probability that the next car to drive by Pablo's house will be red or blue is 12/25 that is option C.

What is probability?

Probability is a measure of the likelihood or chance that a particular event or outcome will occur, expressed as a number between 0 and 1, where 0 represents impossibility (an event that will not occur) and 1 represents certainty (an event that will definitely occur). Probability is used to quantify uncertainty and randomness in various fields, such as mathematics, statistics, physics, economics, engineering, and many other areas of science and everyday life.

Here,

To find the probability that the next car to drive by Pablo's house will be red or blue, we need to add up the number of cars that are red or blue and divide it by the total number of cars recorded.

From the table provided, we can see that the number of blue cars is 70 and the number of red cars is 50. Therefore, the total number of cars that are either red or blue is 70 + 50 = 120.

The total number of cars recorded is given as 250, so the probability of the next car being red or blue is:

Probability = Number of red or blue cars / Total number of cars recorded

Probability = 120 / 250

To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of 120 and 250 is 10.

Probability = 12 / 25

After removing 68.8 kilograms of old copper tubing from air conditioning units Mank takes his load to a recycling yard There he is paid $2.50 per pound. He spent 4 gallons of gas. The cost of gas was 3.051 gat How much money did he make in proft?

Answers

The cost of gas was 3.051, the profit made by Mank is $366.96.

The amount of old copper tubing removed from air conditioning units is 68.8 kg.

The price paid per pound of copper tubing is $2.50.

The amount of gas used is 4 gallons.

The cost of 1 gallon of gas is $3.051.

By using dimensional analysis, we can convert 68.8 kilograms into pounds as shown below,

1 kg = 2.20462 lbs

68.8 kg = 68.8 × 2.20462 lbs= 151.663856 lbs

Using the above obtained value in pounds and the given price per pound, we can determine the total amount he was paid as shown below,

Total amount paid = 151.663856 × 2.5 = $379.16

The cost of 4 gallons of gas is 4 × 3.051 = $12.204

.Subtracting the gas cost from the amount paid, we get the profit,

Mank's profit = Total amount paid - Cost of gas= $379.16 - $12.204 = $366.956 or $366.96 (rounded to two decimal places)

Therefore, the profit made by Mank is $366.96.

give a condition that is sufficient but not necessary for an undirected graph not to have an eulerian cycle. justify your answer.

Answers

A sufficient but not necessary condition for an undirected graph not to have an Eulerian cycle is if the graph contains more than two vertices with an odd degree.

An Eulerian cycle is a path in a graph that visits each edge exactly once and returns to the starting vertex. For a graph to have an Eulerian cycle, it must satisfy two conditions: (1) all vertices must have even degrees, and (2) the graph must be connected.

However, the condition of having more than two vertices with an odd degree is sufficient to guarantee that a graph does not have an Eulerian cycle. This is because in an undirected graph, every edge contributes an even degree to exactly two vertices. If a graph has more than two vertices with an odd degree, it means there are at least three vertices with an odd degree, and therefore it is not possible to construct a closed path that traverses each edge exactly once.

It is worth noting that having more than two vertices with an odd degree is not a necessary condition for a graph to lack an Eulerian cycle. There are cases where a graph with only two vertices of odd degree can still have an Eulerian cycle, as long as the graph remains connected.

The original price of an item is $25, but after the discount, you only have to pay $18.50. What is the discount (as a percent)

Answers

The discount is 26%.

What is Discount?

The discount equals the difference between the price paid for and it's par value. Discount is a kind of reduction or deduction in the cost price of a product.

Given:

\(\bold{Marked} \ \text{price} = \$25\)

\(\bold{Selling} \ \text{price} = \$18.50\)

So,

\(\text{Discount = MP - SP}\)

\(\text{Discount} = 25-18.50\)

\(\bold{Discount} = 6.50\)

Now,

\(\text{D}\% = \dfrac{\text{D}}{\text{MP}} \times100\)

\(\text{D}\% = \dfrac{6.5}{25} \times100\)

\(\text{D}\% = 26\%\)

Answers

The 95% confidence interval for a person's weight gain, measured in pounds, is approximately -6.22 to 25.60 pounds.

To determine the 95% confidence interval for weight gain, we can use the given equation: Whighi = (-94.4395) + (3.7430 × 140.ghtR). Here, Whighi represents weight gain in pounds and 140.ghtR represents the weight measured in lehes.

First, let's calculate the standard error (SE) using the formula: SE = √[(2.0425)² × (0.2945)²]. Plugging in the values, we get SE ≈ 0.609.

Next, we can calculate the margin of error (ME) by multiplying the SE with the critical value corresponding to a 95% confidence level. As the equation provided does not explicitly state the critical value, we'll assume it to be 1.96, which is commonly used for a 95% confidence level. Therefore, ME ≈ 1.96 × 0.609 ≈ 1.196.

Now, we can construct the confidence interval by adding and subtracting the ME from the mean weight gain. The mean weight gain can be found by substituting the given weight measurement of 140.ghtR into the equation Whighi = (-94.4395) + (3.7430 × 140.ghtR). Calculating the mean weight gain, we get ≈ 25.60 pounds.

Thus, the 95% confidence interval for a person's weight gain is approximately -6.22 to 25.60 pounds. This means we are 95% confident that the true weight gain for a person lies within this interval.

B.) p + 0.32p = 1,137.84


C.) 1.32p = 1,137.84


D.) 0.68p = 1,137.84


E.) p(1 + 0.32) = 1,137.84


F.) p − 0.32p = 1,137.84

Answers

The original price of the laptop was $862.00

How to calculate the original price

The original price of the laptop, denoted by x, can be found by setting up an equation that relates it to the final price after markup.

We know that the final price of the laptop is $1,137.84, and that this price is 32% higher than the original price.

So, one way to set up an equation to solve for x is to use the formula:

final price = original price + markup

where the markup is defined as a percentage of the original price.

In this case, we can write:

$1,137.84 = x + 0.32x

Simplifying this equation, we get:

$1,137.84 = 1.32x

To solve for x, we can divide both sides by 1.32:

x = $1,137.84 ÷ 1.32

x = $862.00

So the original price of the laptop was $862.00.

Using this approach, we can see that option C (1.32p = 1,137.84) is the correct equation for finding the original price of the laptop.

Option A (p(1 − 0.32) = 1,137.84) is incorrect because it represents the final price, not the original price.

Option B (p + 0.32p = 1,137.84) is also incorrect because it represents the sum of the original price and the markup, which is not what we need to find.

Option D (0.68p = 1,137.84) is incorrect because it represents a calculation that is not relevant to finding the original price.

Option E (p(1 + 0.32) = 1,137.84) is incorrect because it represents a calculation that adds the markup to the original price, which is not what we need to find.

Option F (p − 0.32p = 1,137.84) is also incorrect because it represents the difference between the original price and the markup, which is not what we need to find.
