Both a frequency table and a frequency distribution are tools used to organize and summarize data, particularly in statistical analysis. They both display the frequency or count of occurrences of each unique value or category in a dataset.

The main difference between a frequency table and a frequency distribution is the type of data they are used to summarize. A frequency table is typically used to display the frequency of occurrence of qualitative or categorical data. It lists the categories or classes of data and the number of observations that fall into each category. For example, a frequency table could display the number of students in a class that received an A, B, C, D, or F grade in a course.

On the other hand, a frequency distribution is typically used to display the frequency of occurrence of quantitative or numerical data. It groups the data into classes or intervals and lists the number of observations that fall into each class or interval. For example, a frequency distribution could display the number of times a coin toss resulted in 0, 1, or 2 heads in a series of 10 tosses.

If Diego makes 10 sandwiches, he will have only 4 slices of cheese left over.

What is Linear equation ?
A linear equation is an algebraic equation in which the highest power of the variable(s) is 1. In other words, it is an equation that represents a straight line on a graph.

The general form of a linear equation with one variable is:

ax + b = 0

Explanation:
The number of slices of cheese Diego uses to make x sandwiches is equal to 2x (since he uses 2 slices of cheese for each sandwich). If he starts with a package of cheese that has 24 slices, then the number of slices of cheese remaining, y, after making x sandwiches is:

y = 24 - 2x

This equation shows that the number of slices of cheese remaining depends on the number of sandwiches Diego makes. As he makes more sandwiches, he will use more cheese and the number of slices of cheese remaining will decrease.
To clarify, the equation is:

y = 24 - 2x

where y represents the number of slices of cheese remaining, and x represents the number of sandwiches Diego makes.

For example, if Diego makes 5 sandwiches, then the number of slices of cheese he uses is 2 times 5, or 10. The number of slices of cheese remaining would be:

y = 24 - 2(5) = 24 - 10 = 14

So, if Diego makes 5 sandwiches, he will have 14 slices of cheese left over.

Similarly, if Diego makes 10 sandwiches, then the number of slices of cheese he uses is 2 times 10, or 20. The number of slices of cheese remaining would be:

y = 24 - 2(10) = 24 - 20 = 4

Using arithmetic operations it is obtained that the patient inhales approximately 29,520 times in a 24-hour day.

What is arithmetic operation?

A subject of mathematics known as arithmetic operations deals with the study and use of numbers in all other branches of mathematics. Basic operations including addition, subtraction, multiplication, and division are included.

We can start by converting the patient's breathing rate from seconds to minutes, since we have the heart rate in minutes.

Use the arithmetic operation of multiplication and division -

The patient inhales once every 3 seconds, which is equivalent to -

(1 inhale / 3 seconds) x (60 seconds / 1 minute) = 20 inhales per minute

Next, we can use the patient's heart rate to find the number of breaths per heartbeat, and then multiply by the heart rate to get the total number of breaths per minute -

Breaths per heartbeat = 1 inhale / 4 heartbeats (since each heartbeat corresponds to 4 phases of the cardiac cycle, during which the patient inhales and exhales once)

Breaths per minute = (Breaths per heartbeat) x (Heart rate)

= (1/4) x 82

= 20.5

So the patient takes approximately 20.5 breaths per minute.

Multiplying this by the number of minutes in a day (24 hours x 60 minutes per hour = 1440 minutes) gives -

Breaths per day = (Breaths per minute) x (Minutes per day)

= 20.5 x 1440

= 29,520

Therefore, the number of inhales is 29,520.

The margin of error for a sample taken from 150 households, with a 95% level of confidence and assuming a standard deviation of 0.5, is approximately 0.080 or 8.0%

To determine the margin of error for a sample taken from 150 households, we need to know the sample size and the level of confidence we want to have in our estimate.

Assuming a 95% level of confidence and a standard deviation of 0.5 (which is a conservative estimate when the population size is much larger than the sample size), the margin of error can be calculated using the following formula:

Margin of error = Z * (σ / √n)

where Z is the Z-score for the desired level of confidence, σ is the standard deviation of the population (or an estimate of it), and n is the sample size.

For a 95% level of confidence, the Z-score is 1.96. Assuming a standard deviation of 0.5, we can calculate the margin of error as:

Margin of error = 1.96 * (0.5 / √150) = 0.080

Therefore, the margin of error for a sample taken from 150 households, with a 95% level of confidence and assuming a standard deviation of 0.5, is approximately 0.080 or 8.0%. This means that the estimate obtained from the sample is likely to be within 8.0% of the true population parameter with 95% confidence.

1. The definition of cosigner of a loan is someone who will promise to pay the loan if the borrower doesn't.

2. She has made late payments which affects her character

3. The cosigner’s current financial situation

4. Capacity, collateral, character

5. The cosigner’s past record of paying on time.

6. They can't qualify for a loan by themselves.

7. The cosigner's financial assets, such as a house or car.

8.  They have a steady job.

9.  A person with a good credit history and a car and house.

1.

The correct definition of a cosigner for a loan is (c) someone who will promise to pay the loan if the borrower doesn't. A cosigner is a person who signs a loan document along with the primary borrower and assumes equal responsibility for the repayment of the loan.

2.

The answer is (d) she has made late payments which affects her character. When someone cosigns a loan, they become equally responsible for repaying the loan. This means that the lender will evaluate the cosigner's creditworthiness and ability to repay the loan just as they would with the primary borrower. The lender will look at factors such as the cosigner's credit score, debt-to-income ratio, and payment history to determine if they are a suitable cosigner.

3.

The correct definition of capacity for potential cosigners is (d) the cosigner's current financial situation. Capacity refers to a cosigner's ability to repay the loan if the primary borrower defaults. The lender will assess the cosigner's income, assets, and liabilities to determine if they have the ability to take on the additional debt.

4.

The correct answer is (a) Capacity, collateral, character. Lenders evaluate a borrower or cosigner's creditworthiness and ability to pay back a loan by analyzing their capacity to repay the loan, the collateral they can offer to secure the loan, and their character.

Capacity refers to the borrower's or cosigner's current financial situation, including their income, job stability, and current debts. Lenders look at this information to determine whether the borrower or cosigner can afford to make payments on the loan.

Collateral refers to assets that the borrower or cosigner can pledge as security for the loan. This could be a car, house, or other valuable property. Lenders use this information to assess the risk of the loan and the likelihood that they will be able to recover the funds if the borrower or cosigner defaults on the loan.

Character refers to the borrower or cosigner's reputation and willingness to repay the loan. Lenders will often check credit reports, payment histories, and references to determine whether the borrower or cosigner is reliable and trustworthy.

5.

The correct definition of character for potential cosigners is (a) the cosigner’s past record of paying on time. Character refers to the borrower or cosigner's creditworthiness and willingness to repay the loan. Lenders will often check the credit report, payment history, and references of the cosigner to determine whether they are reliable and trustworthy.

6.

The correct answer is (a) they can't qualify for a loan by themselves. A borrower may need a cosigner to secure a loan if they do not meet the lender's credit requirements. This could be due to factors such as a low credit score, insufficient income, or a high debt-to-income ratio. By having a cosigner with good credit and financial stability, the borrower can improve their chances of being approved for the loan.

7.

The correct definition of collateral for potential cosigners is (a) the cosigner's financial assets, such as a house or car. Collateral refers to assets that the borrower or cosigner can pledge as security for the loan. This could include a car, house, or other valuable property.

8.

The criteria that makes a person a good cosigner is (b) they have a steady job. A good cosigner should have a stable and consistent income, which shows the lender that they have the financial means to repay the loan if the borrower cannot. This can include a full-time job or other consistent source of income.

9.

The best choice for a cosigner for a car loan would be (b) a person with a good credit history and a car and house. A cosigner with a good credit history and established financial assets can provide additional security for the lender and increase the likelihood of the loan being approved. The presence of collateral, such as a car and house, can also help to secure a lower interest rate for the loan.

Answer:

Step-by-step explanation:

Answer:

Mary was charged a 6% tax

Step-by-step explanation:

To find the percentage tax Mary was charged, we need to determine the amount of tax she paid and then calculate that as a percentage of the original purchase price.

We know that the total bill after tax was $25.44, and the purchase price before tax was $24, so the tax paid must be:

$25.44 - $24 = $1.44

To find the percentage tax charged, we need to divide the tax paid by the original purchase price, then multiply by 100 to express the answer as a percentage:

($1.44 / $24) x 100% ≈ 6%

Therefore, Mary was charged a 6% tax.

The Z score for a 90% confidence interval is nearly 1.645.

A confidence interval is a range of values that, with a given degree of certainty, is likely to contain the real value of a population parameter.

To figure the interval estimate for each sample,

Approximately 90% of these intervals would contain the true population parameter.

To find the Z score for a 90% confidence interval,

We can make use of a calculator or a conventional normal distribution table.

The Z score for a 90% confidence interval corresponds to the point on the standard normal distribution where the area to the right of the Z score is 0.05

(As the confidence interval is split evenly into two tails, each with a probability of 0.05).

Since we are looking for the speed you ran back home, which is r - 3, we can discard the solution of 1.8 (which would give a negative speed) and conclude that you ran back home at a speed of 2.8 miles per hour slower than your speed on the way to the park.

Speed is a measure of how fast an object is moving. It is defined as the distance traveled by the object per unit of time. The most common unit of speed is meters per second (m/s), but other units like kilometers per hour (km/h) and miles per hour (mph) are also used.

Speed is a scalar quantity, which means it only has a magnitude (i.e., the numerical value) and no direction. For example, if a car is traveling at a speed of 60 km/h, we only know how fast it is moving, but we don't know in which direction it is traveling.

Average speed is calculated by dividing the total distance traveled by the time taken to travel that distance. Instantaneous speed is the speed at a particular instant in time and can be found by calculating the rate of change of position with respect to time.

Speed can be influenced by several factors, such as the distance traveled, the time taken to travel that distance, and the presence of obstacles or resistance.

a. The total time you ran can be calculated by adding the time it took you to run to the park and the time it took you to run back home. Let's assume that you ran at a constant speed of "r" miles per hour. Then:

Time to run to the park = Distance / Speed = 18 / r

Time to run back home = Distance / Speed = 15 / (r - 3)

Total time = 18 / r + 15 / (r - 3)

b. To find how fast you ran back home, we can set up an equation using the information given:

Distance = 15 miles

Speed = r - 3 miles per hour (since you were 3 miles per hour slower on the way back)

Time = Distance / Speed

15 / (r - 3) = Time it took to run back home

We don't have enough information to solve for r directly, but we can simplify the equation by multiplying both sides by (r - 3):

15 = Time x (r - 3)

Now we can substitute the expression for the total time we found in part a:

[tex]15 = (18 / r + 15 / (r - 3)) x (r - 3)[/tex]

Expanding and simplifying:

[tex]15r(r - 3) = 18(r - 3) + 15r15r^2 - 45r = 18r - 54 + 15r15r^2 - 48r + 54 = 0[/tex]

Dividing both sides by 3:

5r^2 - 16r + 18 = 0

Using the quadratic formula:

[tex]r = [16 \± \sqrt{(16^2 - 4 \times 5 \times 18)] / 10}r = [16 \± 2] / 10r = 1.8 or 2.8[/tex]

Since we are looking for the speed you ran back home, which is r - 3, we can discard the solution of 1.8 (which would give a negative speed) and conclude that you ran back home at a speed of 2.8 miles per hour slower than your speed on the way to the park.

If the zeros of a quadratic function are 0 and -7, then the function can be written as:

f(x) = a(x - 0)(x - (-7))

Simplifying:

f(x) = a(x)(x + 7)

To find the value of 'a', we can use one of the points on the parabola. Since we know that the x-intercept is 0, we can substitute x = 0 and y = 0 into the equation:
