To calculate the property tax rate, you need to divide the property taxes by the appraised value of the property and then multiply by 100 to express the result as a percentage.

In this case, the property tax rate can be calculated as follows:

Property tax rate = (Property taxes / Appraised value) * 100%

= ($1,650.00 / $112,000.00) * 100%

= 0.014732142857142857 * 100%

= 1.47%

So, the property tax rate in your neighborhood is 1.47%, rounded to the nearest hundredth of a percent.

Answer:  14.25x is the expression

It represents the total combined cost everyone paid.

=======================================================

Explanation:

Add up the price of a ticket, a medium drink, and a large popcorn.

7.50+2.75+4.00 = 14.25

Each person spends $14.25 for those three items.

If x is the unknown number of people, then 14.25x represents the total amount spent by everyone combined.

Example: x = 10 people, so 14.25x = 14.25*10 = 142.50 dollars total is spent by everyone combined.

The measure of angle x is given as follows:

a. x = 30º.

Angle y is complementary with the angle of 60º, meaning that the sum of their measures is of 90º, hence it's measure is given as follows:

y + 60 = 90

y = 30º.

Angle y and angle x form vertical angles, meaning that they are congruent, that is, they have the same measure, hence the measure of angle x is given as follows:

x = y = 30º.

Hence the correct option is given by option a.

The capacity of the tank is 7234.56litres

Capacity refers to the amount of fluid a container can hold. It expressed in units like litres (l), millilitres (ml). Capacity is also known as volume of a substance.

The capacity of the cylindrical pipe is

V = πr²h

r = 8cm

if it takes the pipe 2m per second

then it's volume in one second is

V = 3.14 ×8 × 2× 100

V = 5024cm³/s

if it takes 24 minutes

24 minutes = 24 × 60 s

= 1440s

therefore volume of the tank = 1440 × 5024

The net number of ATP produced from eight molecules of glucose during glycolysis is 32 ATP molecules.

Glycolysis is a metabolic pathway that breaks down glucose into two molecules of pyruvate, which in turn produces ATP. Each molecule of glucose yields two molecules of ATP and two molecules of NADH. Each NADH molecule, in turn, produces three more ATP molecules when it is oxidized in the electron transport chain. Therefore, the total number of ATP produced from one molecule of glucose is four. When eight molecules of glucose undergo glycolysis, the total number of ATP produced is 4 x 8 = 32 ATP molecules. hence 32 ATP molecules produced during the process of glycolysis.

The correct option regarding the slope is given as follows:

The slope of the line of best fit is 0.25. Each time the shoe size increases by one, the height increases by 0.25 inches.

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.

Step-by-step explanation:

0.5p - 3.45 = -1.2.

0.5p = -1.2 + 3.45

0.5p/0.5 = 2.25/0.5

p = 4.5

Answer:

here it is

Step-by-step explanation:

-3 represents the slope. Since its 3/1, this means which point on the slope is 3 to side and 1 either up or down. Since the slope is negative, it goes down.

The formula for a slope is y = mx + b. Since we don’t have the b, that means it is 0. B represents the y intercept or when the line crosses the y axis.

We can start by finding the expected value of X and Y separately: (X) = (0+0+1+1+2+1+0+1+0)/9 = 6/9 = 2/3, E(Y) = (0+0+1+1+2+0+1+0+0)/9 = 5/9

Next, we can expand (X+Y)^2: (X+Y)^2 = X^2 + 2XY + Y^2

Taking the expected value of both sides, we get: E((X+Y)^2) = E(X^2) + 2E(XY) + E(Y^2)

To find E(XY), we can create a table of the possible values of X and Y, and their corresponding probabilities: [table in the attatchment]

So, we have:

E(XY) = 0*(3/9) + 0*(2/9) + 0*(1/9) + 0*(2/9) + 1*(1/9) + 2*(1/9) + 0*(1/9) + 2*(1/9) + 4*(1/9) = 1

Next, we need to find E(X^2) and E(Y^2): E(X^2) = (0^2+0^2+1^2+1^2+2^2+1^2+0^2+1^2+0^2)/9 = 8/9

E(Y^2) = (0^2+0^2+1^2+1^2+2^2+0^2+1^2+0^2+0^2)/9 = 5/9

Putting it all together, we get: E((X+Y)^2) = E(X^2) + 2E(XY) + E(Y^2) = 8/9 + 2*1 + 5/9 = 23/9. Therefore, the answer is 23/9.

98% confidence interval for the proportion of all american adults who would report having earned money by selling something online in the previous year by using z-score. The correct answer is (0.1859, 0.2133)

The point estimate for the proportion of American adults who earned money by selling something online in the previous year is:

p-hat = 914/4579 = 0.1995

To construct a 98% confidence interval for the population proportion, we can use the formula:

p-hat ± z*(sqrt(p-hat*(1-p-hat)/n))

where z is the z-score associated with the desired confidence level (98% corresponds to a z-score of 2.33), and n is the sample size. Plugging in the values, we get:

0.1995 ± 2.33*(sqrt(0.1995*(1-0.1995)/4579))

Simplifying this expression, we get:

(0.1859, 0.2133)

Therefore, the correct answer is (0.1859, 0.2133). This means we are 98% confident that the true proportion of American adults who earned money by selling something online in the previous year lies between 0.1859 and 0.2133.

Answer:

Step-by-step explanation:

To write the Taylor series for the function f(x) = e^(-x) about x = x0 = -1, we first need to find the k-th derivative of f(x) and evaluate it at x = -1.

f(x) = e^(-x)

f'(x) = -e^(-x)

f''(x) = e^(-x)

f'''(x) = -e^(-x)

f''''(x) = e^(-x)

...

The k-th derivative alternates between e^(-x) and -e^(-x), depending on the parity of k.

To evaluate the k-th derivative at x = -1, we substitute -1 into the k-th derivative expression and simplify:

f^k(-1) = (-1)^k * e^1

Now we can write the Taylor series using the formula:

f(x) = f(x0) + (x - x0) f'(x0) / 1! + (x - x0)^2 f''(x0) / 2! + (x - x0)^3 f'''(x0) / 3! + ...

Plugging in the values we obtained earlier, we have:

f(-x0) = e

f'(-x0) = -e

f''(-x0) = e

f'''(-x0) = -e

f''''(-x0) = e

...

Substituting these values into the formula, we get:

f(x) = e - (x + 1)e + (x + 1)^2 e / 2! - (x + 1)^3 e / 3! + (x + 1)^4 e / 4! - ...

Using sigma notation, we can write this as:

f(x) = ∑_{k=0}^∞ (-1)^k (x + 1)^k e / k!

where ∑_{k=0}^∞ represents the sum from k = 0 to infinity.

There is an outlier which is the cost of 6 days of rentals which is $ 168.

To find the range, the formula is :

To find these costs, find the cost of the days of rentals :

1 day :                                  2 days                            3 days :

= 28 x 1                                = 28 x 2                         = 28 x 3

= $ 28                                   = $ 56                          = $ 84

6 days :

= 28 x 6

= $ 168

The range is therefore :

= 168 - 28

= $ 140

To find the Interquartile range, first find the First Quartile and the Third Quartile after ordering the costs:

Order of costs :

28, 28, 28, 56, 56, 56, 84, 84, 84, 168

First quartile position :

= 3 rd position which is $ 28

Third quartile position :

= 3 / 4 x ( n + 1 )

= 3 / 4 x ( 10 + 1 )

= 8 th position which is $ 84

The Interquartile range is :

The transverse axis is a line segment with vertices as its endpoints that traverses the hyperbola's center. The transverse axis's containing line is where the foci are located. The co-vertices serve as the endpoints of the conjugate axis, which is perpendicular to the transverse axis.

The transverse axis is located on the y-axis because of the equation's form, which is y^2a^2-x^2b^2 = 1. The vertices act as the graph's y-intercepts since the hyperbola is centered at the origin.

Three different factors affect the function that determines the balance in this account: the initial deposit amount, the interest rate compounded on this account, and the amount of time the money is kept in the account. The account balance changes if any one or all of these three values is altered.

Let us examine how the interest rate affects this balance. When money is kept in an interest-bearing account, the interest is added as a percentage of the balance to the value of the account. Accordingly, a higher interest rate would result in a larger sum being added to the balance because a larger portion of the balance would be deposited.
