The value went from $45.00 to $68.75. What was the percent change?

The mean change in Mr.60. Connor's bank account is $6.

To find the mean change in Mr. Connor's bank account, we need to add up all the changes and divide by the total number of changes.

First, we can simplify the given list of changes by combining the positive changes and the negative changes separately:

$50.25 + $50.25 = $100.50 (total positive change)

-$22.50 + (-$22.50) + (-$22.50) = -$67.50 (total negative change)

Then, we can find the total change in Mr. Connor's account by subtracting the total negative change from the total positive change:

$100.50 - $67.50 = $33.00 (total change)

Finally, we can find the mean change by dividing the total change by the number of changes:

$33.00 ÷ 5 = $6.60 (mean change)

Therefore, the mean change in Mr.60. Connor's bank account is $6.

In mathematics, the mean is a measure of central tendency that represents the average value of a set of numbers. It is also known as the arithmetic mean or simply the average.

To find the mean of a set of numbers, you add up all the numbers in the set and then divide by the total number of numbers. For example, to find the mean of the numbers 2, 5, 7, and 10, you add them up (2 + 5 + 7 + 10 = 24) and then divide by the total number of numbers (4), which gives a mean of 6.

The mean is often used in statistics to describe the typical or average value of a data set. It is a useful measure of central tendency because it takes into account all the values in the data set, not just a few extreme values. However, the mean can be affected by outliers, or extremely high or low values in the data set that can skew the average.

There are different types of means, including the arithmetic mean, the geometric mean, and the harmonic mean, each with different methods of calculation and specific applications.

The snowstorm resumes at a consistent rate of 2 inches per hour after 5 hours. Draw a second diagonal line with a slope of 2 as a result. Points 7 and 10 should be the beginning and finish of this line, respectively (14,18).

The resulting graph should include a horizontal line at y=10 from (0,4) to (2,10), a diagonal line with a slope of 2 from (7,10) to (0,4), and a horizontal line at y=3 from (0,4) to (0,10). (14,18).

Graphs are visual representations of data that show how any two variables relate to one another. Without requiring a lot of words, they are frequently used to communicate complex and large amounts of data. A specific amount of data must be gathered through surveys or experiments before a graph may be created.

To create the graph of the snow on the ground over time, we can follow these steps:

Start with a point at (0,4) since at the beginning of the storm there were 4 inches of snow on the ground.

From this starting point, draw a diagonal line with a slope of 3, representing the constant rate of snowfall of 3 inches per hour. This line should have a y-intercept of 4 and an x-intercept of 2 (since 6 inches of snow fell in 2 hours).

After the 6 inches of snow have fallen, the snowstorm stops for 5 hours. During this time, the snow on the ground remains the same. So, draw a horizontal line at the y-value of 10 (since there are 10 inches of snow on the ground after the first 6 inches fall).

After 5 hours, the snowstorm starts again at a constant rate of 2 inches per hour. So, draw another diagonal line with a slope of 2. This line should start at the point (7,10) and end at the point (14,18).

The resulting graph should have a diagonal line with a slope of 3 from (0,4) to (2,10), a horizontal line at y=10 from (2,10) to (7,10), and a diagonal line with a slope of 2 from (7,10) to (14,18).

If a homeowner would like to spread shredded bark (mulch) over her flowerbeds. it will cost $65.07 to cover all the flowerbeds with shredded bark.

To calculate the amount of mulch needed, we need to find the volume of each flowerbed and add them together. The recommended depth for the mulch is 4 inches, which is equal to 4/12 = 1/3 feet.

For the first flowerbed, the volume of mulch needed is:

24 ft x 3.1 ft x 1/3 ft = 24.8 cubic feet

For the second flowerbed, the volume of mulch needed is:

14 ft x 4.3 ft x 1/3 ft = 20.87 cubic feet

For the third flowerbed, the volume of mulch needed is:

30 ft x 1.5 ft x 1/3 ft = 15 cubic feet

The total volume of mulch needed to cover all three flowerbeds is:

24.8 cubic feet + 20.87 cubic feet + 15 cubic feet = 60.67 cubic feet

Since there are 27 cubic feet in a cubic yard, the total amount of mulch needed is:

60.67 cubic feet / 27 cubic feet per cubic yard = 2.25 cubic yards

At a cost of $27 per cubic yard, the total cost of the mulch is:

2.25 cubic yards x $27 per cubic yard = $60.75

Therefore, it will cost $60.75 to cover all of the flowerbeds with shredded bark.

Therefore, x³ must be even. Therefore, if -z is irrational, then z must also be irrational.

In mathematics, an integer is a whole number that can be either positive, negative, or zero. It can be written without a fractional or decimal component. Some examples of integers are -3, -2, -1, 0, 1, 2, 3. Integers are used in many different areas of mathematics, including number theory, algebra, and geometry. They are a fundamental concept in mathematics and have many important properties, such as the ability to add, subtract, and multiply them.

Here,

Proof of "x³ is even if and only if x is even":

First, assume that x is even. Then x can be written as x = 2k for some integer k. Substituting this into x³, we get:

x³ = (2k)³ = 8k³ = 2(4k³)

Since 4k³ is an integer, this shows that x³ is even.

Now, assume that x³ is even. This means that x³ is divisible by 2. We can write x³ as x³ = 2m for some integer m. Taking the cube root of both sides, we get:

x = (2m)*(1/3)

If x is an integer, then (2m)*(1/3) must also be an integer. However, the only way for the cube root of an even number to be an integer is if the original number is even. Therefore, x must be even.

Proof of "z is irrational if and only if -z is irrational":

First, assume that z is irrational. By definition, this means that z cannot be expressed as the ratio of two integers. Now suppose that -z is rational. This means that -z can be expressed as the ratio of two integers, say -z = p/q, where p and q are integers and q is not equal to 0. Multiplying both sides of the equation by -1, we get:

z = -p/q

This shows that z can be expressed as the ratio of two integers, which contradicts our assumption that z is irrational. Therefore, if z is irrational, then -z must also be irrational.

Now, assume that -z is irrational. By definition, this means that -z cannot be expressed as the ratio of two integers. We can rewrite this as z = (-1)(-z), which means that z is the product of -1 and a number that is not the ratio of two integers. Multiplying a number by -1 does not change its irrationality, so z must also be irrational. Therefore, if -z is irrational, then z must also be irrational.

The average rate of change of profit as x changes from 3 to 5 is $12 per item.

To find the average rate of change of profit as x changes from 3 to 5, we need to find the change in profit divided by the change in x over that interval:

Average rate of change = (P(5) - P(3)) / (5 - 3)

We can find P(5) and P(3) by plugging those values of x into the profit equation:

P(5) = 2(5)^2 - 4(5) + 6 = 36

P(3) = 2(3)^2 - 4(3) + 6 = 12

Substituting these values, we get:

Average rate of change = (36 - 12) / (5 - 3)

Average rate of change = 24 / 2

Step-by-step explanation:

To find the number that 105 is 33 1/3 of, we can use algebra.

Let x be the number we are looking for. Then we can write the equation:

105 = (33 1/3)% of x

To solve for x, we can first convert the percentage to a decimal by dividing by 100:

33 1/3% = 33 1/3 ÷ 100 = 0.3333

Substituting this in the equation, we get:

105 = 0.3333x

To solve for x, we can divide both sides by 0.3333:

x = 105 ÷ 0.3333

Using a calculator, we get:

x ≈ 315

Therefore, 105 is 33 1/3 of 315.

The correct formula for this scenario is A. =IF(B3>B2, ROUND(B3 - B2, 0), 0).

The IF and ROUND functions are two commonly used functions in Microsoft Excel. Here's a brief explanation of each:

IF Function:

The IF function allows you to test whether a certain condition is true or false, and then perform a specific action based on the result of that test. The basic syntax of the IF function is as follows:

=IF(logical_test, value_if_true, value_if_false)

Here, the "logical_test" is the condition that you want to test. If this condition is true, then Excel will return the "value_if_true". If the condition is false, Excel will return the "value_if_false".

For example, suppose you have a cell A1 that contains a number. You could use the IF function to test whether that number is greater than 10, and then return "Yes" if it is, and "No" if it isn't, using the following formula:

=IF(A1>10, "Yes", "No")

ROUND Function:

The ROUND function allows you to round a number to a specific number of decimal places. The basic syntax of the ROUND function is as follows:

=ROUND(number, num_digits)

Here, the "number" is the number that you want to round, and the "num_digits" is the number of decimal places to which you want to round. If the "num_digits" is positive, then the function will round to the specified number of decimal places to the right of the decimal point. If the "num_digits" is negative, then the function will round to the left of the decimal point.

For example, suppose you have a number in cell A1 that contains many decimal places, and you want to round it to two decimal places. You could use the ROUND function as follows:

=ROUND(A1, 2)

This will round the number in cell A1 to two decimal places.

Here,

The correct formula for this scenario is A. =IF(B3>B2, ROUND(B3 - B2, 0), 0).

This formula uses the IF function to check whether the amount paid (B3) is greater than the amount for which the person is responsible (B2). If this is true, then it subtracts the amount for which the person is responsible from the amount paid and rounds the difference to the nearest whole number using the ROUND function. If the amount paid is not greater than the amount for which the person is responsible, then the formula displays zero.

What is modulus ?
In complex analysis, the modulus of a complex number z = a + bi is a measure of its distance from the origin in the complex plane. Specifically, the modulus is defined as |z| = sqrt(a^2 + b^2), where sqrt denotes the square root. Geometrically, |z| represents the length of the line segment from the origin to the point (a, b) in the complex plane.

Explanation:

The equation |x| = 2 represents the absolute value of x equals 2.

The graph of this equation will be a V-shaped graph that intersects the x-axis at x = -2 and x = 2, and the y-axis at y = 2. The vertex of the V-shaped graph is at the origin (0, 0).

Visually, the graph will look like two lines that start at the origin and extend upwards and downwards at a 45-degree angle, forming a V-shape. The two lines will be symmetric to the y-axis, meaning that the left half of the graph will be a mirror image of the right half.

Step-by-step explanation:

If two sides and the included angle in one triangle are congruent to two sides and the included angle in another triangle, the triangles are congruent.  

The included angle is the angle between two sides of a triangle.

Therefore:

We are told that AN ≅ RW, GN ≅ TW, and ∠N ≅ ∠W.

Therefore, as two sides and the included angle in triangle ANG is congruent to the two sides and the included angle in triangle RWT, the SAS Postulate can be used to prove that the triangles are congruent.

The two given triangles have two sides of equal length, denoted by the same number of tick marks on each congruent line segment.  The included angles are also congruent (both are 90°).  Therefore, the SAS Postulate can be used to prove that the triangles are congruent.

Answer:

Answer:

Step-by-step explanation:

To find the 90% confidence interval for the difference in proportions, we can use the following formula:

CI = (p1 - p2) ± zα/2 * √( (p1 * (1-p1) / n1) + (p2 * (1-p2) / n2) )

where:

p1 and p2 are the sample proportions from the city and rural area, respectively

n1 and n2 are the sample sizes from the city and rural area, respectively

zα/2 is the critical value from the standard normal distribution for a 90% confidence level, which is 1.645

First, we need to calculate the sample proportions:

p1 = 112 / 272 = 0.4118

p2 = 53 / 105 = 0.5048

Next, we can plug in the values and calculate the confidence interval:

CI = (0.4118 - 0.5048) ± 1.645 * √( (0.4118 * (1-0.4118) / 272) + (0.5048 * (1-0.5048) / 105) )

CI = (-0.146, -0.031)

Therefore, the 90% confidence interval for the difference in proportions is (-0.146, -0.031). This means we are 90% confident that the true difference in proportions of religious people between the city and rural areas lies between -0.146 and -0.031. Since this interval does not include zero, we can conclude that the proportion of religious people is significantly different between the two areas.
