Step-by-step explanation:

Michael needs to pay car insurance premiums of $958 two times per year. Since a year has 52 weeks, this means he needs to pay $958 * 2 = $1916 per year.

Since his paycheck is bi-weekly, he needs to make a deposit of $1916 / 26 = $73.54 from each paycheck to cover the expense.

So Michael should deposit $73.54 from each bi-weekly paycheck to a savings account for "Other Expenses (Predictable)" to cover the car insurance premiums.

The length of the four-acre lot with front footage of 250 feet is approximately 693.76 feet.

In mathematics, "acre" is a unit of area that is commonly used to measure the size of a piece of land. One acre is equal to 43,560 square feet. To find the length of the lot, we need to know the area of the lot and the front footage.

Here we need to determine the length of a four-acre lot with front footage of 250 feet, we need to use the concept of area and the formula for calculating the area of a rectangle.

In this case, the area of the lot is four acres, or

=> 4 x 43,560 = 173,440 square feet.

In order to find the length of the lot, we can divide the area by the front footage, which is 250 feet.

By using the formula for the area of a rectangle, we can write this as:

=> Area = Length x Front Footage

Therefore, Length  is calculated as

=> Area / Front Footage = 173,440 / 250 = 693.76 feet.

Step-by-step explanation:

Let x be the number of black ink cartridges sold and y be the number of color ink cartridges sold. We know that:

x + y = 36 (total number of cartridges sold)

18.99x + 22.99y = 723.64 (total amount of money earned)

We can use the first equation to solve for one variable in terms of the other and substitute that expression into the second equation to get a single equation in one variable, which can then be solved. For example:

y = 36 - x

18.99x + 22.99(36 - x) = 723.64

18.99x + 827.64 - 22.99x = 723.64

-4x = -104

x = 26

So, 26 black cartridges were sold and 36 - 26 = 10 color cartridges were sold.

3.17 is the meaning of the x - value when y = 81. This equation can be solved using the concept of equation solving.

A statistical word used to express a straight-line relationship between two variables is a linear relationship (or linear association). Graphs and mathematical equations of the type y = mx + b can both be used to represent linear connections. The quantity of hours worked in relation to income is an illustration of a linear connection. The independent variable would be the number of hours worked, and the dependent variable would be the amount of money made.

Linear relationship can be represented by the equation y = 62 + 6x where y represents the expected quiz score and x represents hours spent on homework that week.

when y = 81, then: y = 62 + 6x

or, 81 = 62 + 6x

F(n + 1) + F(n – 2) = 2F(n) for n ≥ 3 using fibonacci numbers definition is proved.

What is a Fibonacci  sequence ?

The Fibonacci sequence is a number sequence in which each subsequent number is formed by adding the two numbers that came before it. The series is named after the Italian mathematician who devised it.

Fibonacci numbers are defined as follows:

F(0) = 0

F(1) = 1

F(n) = F(n-1) + F(n-2) for n ≥ 2

Now, let's prove that F(n + 1) + F(n – 2) = 2F(n) for n ≥ 3 using this definition:

F(n + 1) = F(n) + F(n - 1) (by definition)

F(n – 2) = F(n - 3) + F(n - 4) (by definition)

Adding these two equations, we get:

F(n + 1) + F(n – 2) = F(n) + F(n - 1) + F(n - 3) + F(n - 4)

Now, using the definition of F(n) = F(n-1) + F(n-2), we can substitute F(n-1) + F(n-2) for F(n):

F(n + 1) + F(n – 2) = F(n) + F(n) = 2F(n)

Therefore, F(n + 1) + F(n – 2) = 2F(n) for n ≥ 3, which is the desired result.

Hence, F(n + 1) + F(n – 2) = 2F(n) for n ≥ 3 using fibonacci numbers definition is proved.

Answer: Fingering makes transistors which are connected in series, mulpliers create transistors which are connected in parallel.

Step-by-step explanation:

"Fingers" and "multipliers" are terms used in mathematics and specifically in multiplication to help perform calculations faster and with more accuracy.

"Fingers" is a method of multiplication that uses fingers on one's hand as a visual aid to keep track of numbers being multiplied. The method is often used by children who are learning how to perform basic multiplication, as it provides a concrete way of visualizing the problem. The student would put up a certain number of fingers on one hand to represent one of the numbers being multiplied, and then use the other hand to count the number of times that the first number is being multiplied.

"Multipliers" are a set of pre-memorized values that can be used to perform multiplication more quickly. These values are usually small, and when multiplied by 10, 100, 1000, and so on, give the result of more complex multiplication problems. For example, one common multiplier is 9, which can be used to quickly multiply any number between 90 and 99, such as 93 * 9 = 837. Knowing these multipliers is a key part of mental math and helps to perform calculations faster and with more accuracy.

The probability that two grandchildren of the woman who are first cousins to one another will each inherit the dominant allele is 1/16.

To determine the probability that two grandchildren of a woman who are first cousins to one another will each inherit the dominant allele, we first need to understand the pattern of inheritance for dominant and recessive alleles.

Assuming the woman has two dominant alleles (D) and two recessive alleles (d), the probability of passing on a dominant allele to each grandchild is 1/2. For two first cousins to each inherit a dominant allele, we need both of their parents to pass on a dominant allele to them. The probability of both parents passing on a dominant allele is (1/2) * (1/2) = 1/4.

So, the probability of two first cousins each inheriting a dominant allele is 1/4 * 1/4 = 1/16. This means that there is a 1 in 16 chance that both first cousins will each inherit the dominant allele.

To summarize:

P(inheriting dominant allele) = 1/2

P(both parents passing on dominant allele) = 1/2 * 1/2 = 1/4

P(two first cousins each inheriting dominant allele) = 1/4 * 1/4 = 1/16

Therefore, the probability that two grandchildren of the woman who are first cousins to one another will each inherit the dominant allele is 1/16.

The average decrease in temperature of the liquid from 1:00 p.m. to 10:00 p.m. is approximately 0.8°C per hour.

The concept used in this calculation is average rate of change. The average rate of change is the change in a quantity (in this case, temperature) over a certain time period (in this case, 9 hours), expressed as a ratio or per unit of time. In this calculation, we are finding the average decrease in temperature per hour.

To find the average decrease, we need to find the difference between the starting temperature (14.7°C) and the final temperature (-6.8°C), and then divide by the number of hours that passed, which is 9 hours.

Therefore:

(14.7°C - (-6.8°C)) / 9 hours = 21.5°C / 9 hours = 2.39°C per hour

Rounding to the nearest whole number, we have:

2.39°C per hour ≈ 2.4°C per hour = 0.8°C per hour.

You can resolve the equation by completing the square. first, subtract 0.33 from both sides of the equation. Add 968.15/0.33 to both sides after that. The resulting equation will be x2 + 189.94 x = 2113.58. Divide both sides by 189.94, then multiply both sides by 0.5.  To find x=-93.97, square root both sides of the equation.

-0.33x^2 + 63.78x - 968.15 = 0

x2 + 189.94x = 2113.58 after subtracting -0.33 from both sides.

Multiply both sides by 189.94 to get 11.27 (x + 94.97).

To all sides, add 0.5: x + 94.97 + 0.5 = 11.77

Add up both sides and subtract 94.97: x + 0.5 = 11.77 - 94.97

Add 0.5 on either side to get the result: x = 11.27 - 94.97 x = -93.97

By completing the square, the equation -0.33x2 + 63.78x - 968.15 = 0 can be resolved. first, subtract 0.33 from both sides of the equation. As a result, the equation x2 + 189.94x = 2113.58 will be produced. Divide both sides by 189.94, then multiply both sides by 0.5. The outcome will be (x+94.97)2=2403.55. Square root both sides of the equation to finish. As a result, x + 0.5 = 11.27 - 94.97 will be obtained.
