Answer:

7:9

Step-by-step explanation:

The basic ratio is 63:81 but to simplify this ratio you can simplify each number as a multiplication of its factors.

63=3*3*7

81=3*3*3*3

Now find the factors they have in common and get rid of them.

63=3*3*7

81=3*3*3*3

The numbers in bold are all the factors that they have in common.

You can cancel these numbers out.

Now the remaining numbers you can put into a ratio in the same order

7:3*3

The annual return of the investment is 31.1%.

Given that, person has purchased a single-family home that you intend to rent for $850 per month.

A return, also known as a financial return, in its simplest terms, is the money made or lost on an investment over some period of time.

First find the amount earned per year:

= 850 x 12

= $10,200

The yearly expenses would be:

= (390 x 12) + (60 x 12) + (340 x 2) + 500 + (100 x 12)

= 4,680 + 720 + 680 + 500 + 1,200

= $7,780

The annual ROI is:

= (10,200 - 7,780) / 10,200 x 100%

= 31.1%

Therefore, the annual return of the investment is 31.1%.

The dimension of a rectangle is 23m and 23m.

Here we have to find the area of a rectangle as large as possible.

Data given:

Perimeter = 92m

The formula for the perimeter of the rectangle:

perimeter = 2(length + breadth)

92 = 2( l + b)

l + b = 46

We have to find the largest area, so when we will take the length and breadth same then we get the largest area.

So length = breadth

2 length = 46

length = 23m

length = breadth = 23m

Therefore the dimensions are 23m and 23m.

The percentage of income that a person or corporation must pay or withhold as taxes is known as the effective tax rate. The effective tax rate is 10.15%. Here option A is the correct answer.

The term effective tax rate refers to the average tax rate that an individual pays on both earned and unearned income, such as stock dividends. According to the progressive tax model, when income rises, the tax rate also rises, putting persons in a higher tax bracket.

Here, the presented data shows that the marginal tax rate is 22% for taxable income in the $40,526 to $86,375 income range.

Effective tax rate = total taxes owed/taxable income × 100.

Effective tax rate = $6,847.50/$67,400 × 100.

The tax rate in effect = 10.15%

Complete question:

Having a total tax liability of $6,847.50, a taxable income of $67,400, and a marginal tax rate of 22%. Determine the effective tax rate for a taxable income of $75,400. round the final answer to the nearest hundredth.

To write an area, you need to know the shape and the measurements of the sides.

For example, if you have a square, you can calculate its area with the formula A = s², where A is the area and s is the length of a side.

If the side is 10 cm, then the area would be written as A = 10² = 100 cm².

1. Identify the shape of the area you are trying to calculate.

2. Calculate the measurements of the sides.

3. Use the appropriate formula to calculate the area. For example, for a square, use the formula A = s², where A is the area and s is the length of a side.

4. Plug in the measurements and calculate the area.

5. Write the area using the correct unit of measurement. For example, if the side was 10 cm, the area would be written as A = 10² = 100 cm².

Answer:

Equation: 154 = 158n - 132 n = 11/6

Step-by-step explanation:

Let's start by converting this into an equation. Some keywords to look for are "is" which means an equal sign (=), "product" which is multiplication (*), and "decreased" which means a minus sign (-):

So this is our equation: 154 = 158n - 132

Now we have to solve for n:

First, we add 132 to both sides to isolate the n more:

286 = 158n

Then to completely isolate the n, we divide both sides by 158

286

------    =     n

156

n = 11/6, final answer.

Thus, the amount he deposited four years ago is 5600.

Simple interest is used to determine the amount of interest that will be charged on a sum of money at a specific rate and for a specific amount of time. The principal amount in simple interest does not change, in contrast to compound interest, which adds the interest from the principal of preceding years to determine the interest of the following year.

Here,

Given:

The amount of electrician account earned is 1680

thus total amount is = 1680 + x

where x is the principal amount

Interest rate = 7.5%

and total years = 4 years

Using formula

[tex]\frac{P*R*T}{100}[/tex]= Simple interest

=> 1680 = x*7.5*4/100

=>1680 =x * 30/100

=>1680* 100 /30 = x

=>5600

Thus, the amount he deposited four years ago is 5600.

Answer:

y = 3x + 2

Step-by-step explanation:

y = 3x + c

substitute x and y with one of the points (ex: (1,5)):

5 = 3(1) + c

5 - 3 = c

2 = c

so

y = 3x + 2

To make sure this is correct, substitute x and y with the other point (ex: (-3,-7)):

-7 = 3(-3) +2

-7 = -9 + 2

-7 = -7

that means the equation is true and as it passes through both points.

Answer:It was not until the eighteenth century that mathematician Leonard Euler (1707-1783) discovered a relationship between the three classical triangle centers.

Step-by-step explanation:

The probability of one name drawn from the hat is 0.7 if a hat contains the names of seven boys and three girls.

We know that probability is defined as the division of number of favorable outcomes to the total number of outcomes.

In hat number of names of boys are =7 and

number of names of girls are =3

So, total number of names are =number of boys names + number of girls names

=>total number of names are =7+3

=>total number of names are=10

Now, number of boys are =7

So, count of favorable outcomes is =7 and total number of outcome is 10

=>Probability of choosing a boy name is =number of favorable outcome/total number of outcome

=>P(E) = 7/10

=>P(E)=0.7

Hence, required probability is 0.7

c. the observations must be independent

A Chi-square test is a hypothesis testing method. Two common Chi-square tests involve checking if observed frequencies in one or more categories match expected frequencies.

Types of Chi-square tests

You use a Chi-square test for hypothesis tests about whether your data is as expected. The basic idea behind the test is to compare the observed values in your data to the expected values that you would see if the null hypothesis is true.

There are two commonly used Chi-square tests: the Chi-square goodness of fit test and the Chi-square test of independence. Both tests involve variables that divide your data into categories. As a result, people can be confused about which test to use. The table below compares the two tests.

The permutation combination is 120 for 3 different topping pizzas are available.

Permutation Combination:

A variety of ways to select objects from a set, usually forming a subset without replacement. The selection of this subset is called a permutation if the order of selection is a factor, and a combination if the order is not a factor. The French mathematicians Blaise Pascal and Pierre de Fermat, in the 17th century, used many chances in his game of combinatorics and probability by considering the ratio of the number of required subsets to the number of all possible subsets stimulated the development of the theory.

The concepts of permutations and combinations and their differences can be illustrated by examining all the different ways of selecting pairs of objects from five identifiable objects such as the letters A, B, C, D and E.

According to the Question:

Given that :
