Answer:

3,975.16 United States Dollar

Step-by-step explanation:

The following equation is m=d-10+k×i represent the total amount in account(m) in dollar.

Although the question does not specify the options, but I have specified my answer as follows:

Given:

The equation representing the total amount in the account, m, when starting with d dollars and being charged a 10$ fee.

Account Opening Charges: $10

Starting amount: $d

The total amount in the account: $m

Let us say the depositor deposits an amount $k for 'i' number of months

Banks deduct their charges from the account balance itself, hence account opening charges are deducted from the bank balance.

I have assumed an amount $k invested every month. You can remove that term as per the requirement of the question.

The total amount at a point in time = starting amount - Account Opening Charges + monthly deposit till that time

⇒m=d-10+k×i

This equation shows that the total amount in the account will be equal to the initial deposit minus the fee charged by the bank.

Therefore, the following equation is m=d-10+k×i.

Wyoming's population will surpass Alaska's approximately 28.8 years after 2006, or in the year 2035.

A differential equation is a mathematical equation that relates a function with its derivatives. It expresses a relationship between a function and its rate of change.

An example of a differential equation is the simple equation dy/dx = 2x, which describes the rate of change of a function y with respect to x.

To determine when Wyoming's population will surpass Alaska's, we need to set the two population equations equal to each other and solve for t:

515,000e^(0.020t) = 670,000e^(0.012931t)

Dividing both sides by 515,000:

e^(0.020t) = 1.30291262136e^(0.012931t)

Taking the natural logarithm of both sides:

0.020t = ln(1.30291262136) + 0.012931t

Simplifying:

0.007069t = ln(1.30291262136)

Solving for t:

t = ln(1.30291262136) / 0.007069

t ≈ 28.8

Organic foods in local stores are typically more expensive than conventional foods. The table compares recent organic and conventional prices per pound for carrots and apples. Using the table, we can determine whether the organic prices vary directly with the conventional prices.

According to the data in the table, it can be noticed that the organic prices do vary directly with the conventional prices because the ratios of organic price per pound to conventional price per pound are constant. Therefore, we can say that the organic prices vary directly with the conventional prices. We can identify k by using the carrot data which is $1.51 per pound and $0.77 per pound.1.51/0.77 = 1.962 k = 1.962Therefore, k = 1.962 does vary directly with the conventional prices. We can also determine if the total cost of organic apples varies directly with the number of pounds of organic apples purchased. If they do, we can identify k. According to the data in the table, we can say that the total cost of organic apples varies directly with the number of pounds of organic apples purchased because the ratios of total cost to the number of pounds are constant.

The solution expressed in inequality notation is x < 0 or 0 < x < 3 or x > 3.

To solve the inequality x² + 35 > 12x, we can rearrange it to the standard quadratic form and solve for x:

x² - 12x + 35 > 0

To find the solution, we can create a sign chart by examining the signs of the expression x² - 12x + 35 for different intervals of x.

Consider x < 0:

If we substitute x = -1 (a negative value) into the expression, we get:

(-1)² - 12(-1) + 35 = 1 + 12 + 35 = 48 (positive)

So, in the interval x < 0, the expression x² - 12x + 35 > 0 is true.

Consider 0 < x < 3:

If we substitute x = 2 (a positive value) into the expression, we get:

2² - 12(2) + 35 = 4 - 24 + 35 = 15 (positive)

So, in the interval 0 < x < 3, the expression x² - 12x + 35 > 0 is true.

Consider x > 3:

If we substitute x = 4 (a positive value) into the expression, we get:

4² - 12(4) + 35 = 16 - 48 + 35 = 3 (positive)

So, in the interval x > 3, the expression x² - 12x + 35 > 0 is true.

Now, let's combine the intervals where the inequality is true:

The solution expressed in inequality notation is x < 0 or 0 < x < 3 or x > 3.

To assess the correctness of the curved arrow notation in each case, specific examples or instances of the notation are needed. Without such examples, it is challenging to provide a meaningful analysis or explanation of whether the curved arrow notation is correct or incorrect.

Curved arrow notation is commonly used in organic chemistry to represent electron movement in chemical reactions and mechanisms. It indicates the flow of electrons, such as the movement of lone pairs, bonding electrons, or the formation/breakage of bonds. The notation is essential for understanding reaction mechanisms and the distribution of electron density in molecules.

To determine the correctness of curved arrow notation, one needs to evaluate whether it accurately represents the movement of electrons according to the established rules and principles of organic chemistry. This involves considering factors such as electron pair repulsion, formal charges, bond breaking/forming, and resonance structures.

Without specific examples or instances of the curved arrow notation in question, it is not possible to provide a comprehensive analysis or explanation. If you can provide specific examples or questions regarding the curved arrow notation, I would be glad to assist you further.

Every pair of real numbers in B can be mapped to by f(x) for some pair (a,b) in A, which means the function is onto. As the function is one-to-one and onto, it is a bijection.

(a) The function f(x)=x-1 from A=B=Z is one-to-one, not onto and not a bijection.

The given function f(x) subtracts 1 from each element of the set A. Since each element of A has only one unique predecessor in A, the function is one-to-one. However, there exists no element in B that can be mapped to by f(x) for any negative integer in A, which means the function is not onto. As the function is not onto, it is not a bijection.

(b) The function f(x)=|x| from A=R and B={x:x∈R,x≥0} is not one-to-one, not onto, and not a bijection.

The absolute value function f(x) maps every element of A to a non-negative value in B. Since both positive and negative numbers in A are mapped to the same non-negative value in B, the function is not one-to-one. Additionally, there are no negative values in B that can be mapped to from A, which means the function is not onto. As the function is not one-to-one and not onto, it is not a bijection.

(c) The function f((a,b))=a from A=R×R and B=R is not one-to-one, onto, and not a bijection.

The function f((a,b))=a maps each element of A to its first component. Since different pairs in A can have the same first component, the function is not one-to-one. However, every real number in B can be mapped to by f(x) for some element (a,b) in A, which means the function is onto. As the function is not one-to-one and onto, it is not a bijection.

(d) The function f((a,b))=(a+b,a−b) from A=B=R×R is one-to-one, onto, and a bijection.

The function f((a,b))=(a+b,a−b) maps each element of A to a unique element in B. Since each pair (a,b) in A corresponds to a unique pair of values in B, the function is one-to-one. Additionally, every pair of real numbers in B can be mapped to by f(x) for some pair (a,b) in A, which means the function is onto. As the function is one-to-one and onto, it is a bijection.

Polling mistakes are frequently caused by poorly written questions. People frequently misunderstand questions that are worded strangely and react to the question inaccurately, which leads to an error in the polling data. Due to misinterpretation, people frequently react differently than they would typically say , then option c is correct.

Limited respondent selections, a lack of knowledge, difficulty assessing intensity, and lack of interest in political matters are just a few of the factors that might make a poll unreliable.

Survey mistake, fewer respondent alternatives, a lack of knowledge, problems assessing intensity, and a lack of interest in political matters are some potential polling weaknesses.

The drawback of polling is that if there are too many devices to check, it may take longer to service an I/O device than it does to poll all of the devices.

A normal distribution has a mean of 120 and a standard deviation of 10 then P(x > 110) is 0.84

Given that mean is 120 and a standard deviation of 10

The z-score for x=110 can be calculated as:

z = (x - μ) / σ = (110 - 120) / 10 = -1

Using a standard normal distribution table

we can find that the probability of a z-score being greater than -1 is 0.8413.

Therefore, P(x > 110) = 1 - P(x ≤ 110)

= 1 - P(z ≤ -1)

= 1 - 0.1587

= 0.8413.

Hence,  a normal distribution has a mean of 120 and a standard deviation of 10 then P(x > 110) is 0.84
