What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here: Sales tax

A sales tax is a consumption tax imposed by the government on the sale of goods and services. A conventional sales tax is levied at the point of sale, collected by the retailer, and passed on to the government.

Now it costs $15.00 and the tax is 7%

Treating the taxable amount as $15 and now to find 7% equivalent we get

Now 7%×15=$1.05

Thus he has to pay $1.05 in taxes

Answers

As per normalization, the session table uses the third normal form

Normalization is an important step in designing a database, as it helps to eliminate issues such as data integrity and redundancy. This is achieved through a series of steps, known as normalization.

The Sports Physical Therapy Center database has a table named Session that keeps track of all therapy appointments at the center. The table contains various pieces of information such as the session number, date, patient number, length of session, therapist ID, therapist's last and first name, and the therapy code.

the sum of 4.5 and one-third a number is equal to at most 38.9. what are all the possible values of the number? how would you write an inequality that could be used to solve this problem?(1 point)

Answers

The possible values of the number x are any real number that is less than or equal to 103.2. This can be written as: x <= 103.2

Let's call the number "x".

The sum of 4.5 and one-third of x can be written as:

4.5 + (1/3)x

The inequality to represent the statement "the sum is equal to at most 38.9" would be:

4.5 + (1/3)x <= 38.9

To solve for x, we can isolate x by subtracting 4.5 from both sides:

(1/3)x <= 34.4

And finally, multiplying both sides by 3:

x <= 103.2

So, all the possible values of the number x are any real number that is less than or equal to 103.2. This can be written as:

x <= 103.2

During a football play, Odell Beckham Jr. Runs a straight route 40 yards up the sideline before

turning around and catching a pass thrown by Eli Manning. On the opposing team, a

defender who started 20 yards across the field from Beckham saw the play setup and ran a

slant towards Beckham What was the distance the defender had to run to get to the spot

where Beckham caught the ball?

Answers

The distance the defender had to run to get to the spot where Beckham caught the ball is 34.6 yards.

Let's call the distance the defender had to run to get to the spot where Beckham caught the ball "d".

Since the defender was running aslant towards Beckham, we can use the Pythagorean theorem to find the distance he had to run. The theorem states that in a right triangle, the sum of the squares of the two smaller sides is equal to the square of the hypotenuse (the longest side).

If we call the sideline 40 yards, we can set up the equation as follows:

d² + 20² = 40²

Expanding and simplifying:

d² + 400 = 1600

d² = 1600 - 400 = 1200

d = √(1200)

= √(300 * 4)

= √(300) * √(4)

= √(300) * 2

= 10 √(3) * 2

= 20 √3

Rounding to the nearest tenth, we have:

d ≈ 34.6 yards

So, the defender had to run approximately 34.6 yards to get to the spot where Beckham caught the ball.

What is the SAS criteria for triangle similarities

The SAS(side–angle–side) criterion for triangle similarity states that If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed by the two sides in both the triangle are equal, then two triangles are said to be similar.

Observing the triangles, if the ratio of side lengths 24 and 120 is equal to that of 14 and (14 + 56), then the angles inscribed by the two sides are in both triangles are equal.

24 : 120 = 24/120

Answers

Any probability statement involving a normal random variable can be converted to an equivalent statement involving a standard normal random variable through the process of standardization.

Standardization is converting a normal random variable, X, to a standard normal random variable, Z, by subtracting its mean, μ, and dividing by its standard deviation, σ. The formula for standardization is given:

Z = (X - μ) / σ

Once a normal random variable has been standardized, it is easier to find probabilities because the standard normal distribution is well-known and widely used in statistical analysis. For example, if X is normally distributed with mean μ and standard deviation σ, the probability of X being between two values a and b can be found using the cumulative distribution function (CDF) of the standard normal distribution.

one fruit punch has fruit juice and another is fruit juice. how much of the punch should be mixed with of the punch to create fruit punch that is fruit juice?

Answers

The below calculation allows us to determine the amount of fruit juice and punch needed to create a fruit punch that is entirely fruit juice.

To create a fruit punch that is entirely fruit juice, we must calculate the ratio of fruit juice to total punch. To do this, we will use the following formula:

Fruit Juice Ratio = (Fruit Juice / (Fruit Juice + Punch)) x 100

For example, if we have 10 ounces of fruit juice and 10 ounces of fruit punch, the ratio of fruit juice to total punch is 50%. Therefore, we need to mix 50% fruit juice with 50% punch to create a fruit punch that is entirely fruit juice.

To calculate this for any given amount of fruit juice and punch, we simply plug the numbers into the formula. For instance, if we have 20 ounces of fruit juice and 60 ounces of punch, the ratio of fruit juice to total punch is 25%. Therefore, we need to mix 25% fruit juice with 75% punch to create a fruit punch that is entirely fruit juice.

By using this formula, we can easily determine the amount of fruit juice and punch needed to create a fruit punch that is entirely fruit juice.

We can use the formula Fruit Juice Ratio = (Fruit Juice / (Fruit Juice + Punch)) x 100 to calculate the ratio of fruit juice to total punch. This allows us to determine the amount of fruit juice and punch needed to create a fruit punch that is entirely fruit juice.

Carmony Computer Consultants charges a $255 fee plus $85 per hour for its work. Holliday Computer Work charges a flat rate of $115 per hour. For how many hours of work is it cheaper to hire Carmony?

Answers

Answer: Let's call the number of hours worked h.

The cost of hiring Carmony is $255 + $85h.

The cost of hiring Holliday is $115h.

We want to find the number of hours h such that $255 + $85h is less than $115h.

We can write this as:

$255 + $85h < $115h

Subtracting $115h from both sides:

$255 < $115h - $85h

Combining like terms:

$255 < $30h

the circumference of a circular pond is 44cm.What is the diameter of the fish pond?

Answers

The pond is circular, so we can apply circle formulas. In this case, we can use the circumference of a circle formula and input the corresponding variable in and solve for the diameter.

Circumference of a circle formula:

C=2πr, where C=circumference and 2r=diameter

We can rearrange the formula using the commutative property of multiplication to get 2r, which 2r=diameter (d):

C=π•2r

Now that we have 2r, we can substitute in d:

C=π•d

We know that C=44cm, so we can substitute it in and solve for d:

(44)=π•D

Divide both sides by π:

44/π=D

14.005≈D

Apply the symmetric property

D≈14.005cm

mean = 0.4, standard deviation = .396

We cannot find the mean and standard deviation since the probability distribution table is not given.

Answers

Mean = μ = 0.40

Standard deviation = σ = 0.015

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Female colorblindness proportion = 1%

Male colorblindness proportion = 8%

Female sample size = 40

Male sample size = 20

Hence, We get;

Let us check if the condition np ≥ 10 is satisfied or not,

⇒ np

⇒ 40 × 0.01

⇒ 0.4 < 10

Since, the condition np ≥ 10 is not satisfied the binomial random variable cannot be well approximated by a normal random variable. A larger sample size would be required to satisfy the condition np ≥ 10.

Hence, The mean is,

μ = np

μ = 40*0.01

μ = 0.40

And, The standard deviation is,

σ = √p(1 - p)/n

σ = √0.01(1 - 0.01)/40

σ = 0.015

Thus, We get;

Mean = μ = 0.40

Standard deviation = σ = 0.015

(1/4 + 1/2) - 2/3

Answers

(1/4 + 1/2) - 2/3 is the question i will be solving for you.

Step by Step:

You always want to start with the parentheses according to the PEMDAS rule. (Parentheses, Exponents, Multiply or Divide, Add or Subtract)

So, you first will do (1/4 + 1/2). They do not have the same denominator so you will find the common denominator.

If we want the denominator to be the same, we know we can do 1/2 × 2/2 because it'll make both denominators the same.
2 × 2 = 4
1 × 2 = 2

Now, our equation is (2/4 + 1/4) - 2/3.

Let's solve the equation in the parentheses.
2 + 1 = 3
The denominator stays 4.

Now, our equation is 3/4 - 2/3.
The denominator are not the same. So, our common denominator is going to be 12.

4: 4, 8, 12
3: 3, 6, 9, 12

To get the fractions to have the same denominator:

3/4 × 3/3 = 9/12
2/3 × 4/4 = 8/12

Now, our equation is 9/12 - 8/12.

9 - 8 = 1
The denominator stays the same.

So, (1/4 + 1/2) - 2/3 = 1/12.

Which fee pays for services such as a credit score check, an attorney, and a notary?

Answers

Typically, these services are covered by closing costs associated with a real estate transaction. Closing costs are fees charged by various parties involved in the home-buying process and can include the cost of a credit score check, attorney fees, and notary fees.

A credit score check is often required by a lender as part of the mortgage approval process, and the fee for this service can be included in the closing costs. The fee for an attorney can also be included in closing costs, especially if the attorney is hired to review and explain the closing documents. An attorney can also represent the buyer or the seller during the closing process and advise them of their rights and obligations.

A notary is typically required to witness the signing of legal documents, such as the mortgage or deed, and a notary fee can also be included in the closing costs. The exact amount of each of these fees can vary, and it's common for buyers to receive an estimate of their total closing costs from their lender prior to closing.

It's important to note that closing costs are separate from the down payment and can add several thousands of dollars to the overall cost of buying a home, so it's a good idea for buyers to carefully review their closing cost estimate and understand what each fee covers.

Answers

The Histogram shows the distribution of the students’ balance-scale readings is Histogram II.

The distribution of numerical data is roughly shown by a histogram. Karl Pearson was the one who initially coined the phrase. The first stage in creating a histogram is to "bin" (or "bucket") the range of values, or split it into a series of intervals, and then count the number of values that fall into each interval.

The bins are often defined as a series of discrete intervals that don't overlap. The bins (intervals) must be close together and frequently, but not always, have the same size.

When the mean and median are equal, a histogram is said to be symmetrical. A symmetric histogram will be split into two equal halves if we draw a line through its centre. The two parts will be exact replicas of one another.

In part (a), the y-intercept is (0,3), which means that when x = 0, the value of f(x) is 3. In part (b), the y-intercept is (0,0), which means that when x = 0, the value of f(x) is 0. In part (c), the y-intercept is (0,-6), which means that when x = 0, the value of f(x) is -6.

What do you mean by transformation?

A transformation of a function is a process that changes the position or shape of the function on a coordinate plane. There are several types of transformations, including:

Translation: A translation moves the graph of a function horizontally or vertically, but does not change its shape. This can be accomplished by adding or subtracting a constant to the input or output of a function.

Scaling: A scaling changes the size of a function's graph, but not its shape. This can be accomplished by multiplying the input or output of a function by a constant.

Reflection: A reflection flips the graph of a function over a line. This can be accomplished by negating either the input or the output of a function.

Stretching or Compression: A stretching or compression changes the height or width of a function's graph, but not its shape. This can be accomplished by multiplying the output of a function by a constant greater than 1 for stretching, or by a constant between 0 and 1 for compression.

These transformations can be used to shift, scale, reflect or distort the graph of a function, allowing for greater understanding and analysis of its properties.

a. f(x) = [tex]3(2)^{x}[/tex] + 3 is an exponential function that has been vertically shifted up by 3 units. The y-intercept is (0,3), which means that when x = 0, the value of f(x) is 3.

b. f(x) = [tex]6(4)^{x}[/tex] * 0.5 is an exponential function that has been vertically stretched by a factor of 0.5 and horizontally stretched by a factor of 6. The y-intercept is (0,0), which means that when x = 0, the value of f(x) is 0.

c. f(x) = [tex]4(0.5)^{x}[/tex] - 6 is an exponential function that has been vertically shifted down by 6 units. The y-intercept is (0,-6), which means that when x = 0, the value of f(x) is -6.

ermias can paint a room in 8 hours. manuel can paint the same room in 6 hours. how long does it take for ermias and manuel to paint the room if they are working together?

Answers

It takes Ermias and Manuel 3.43 hours to paint the room if they are working together. To find the time it takes for Ermias and Manuel to paint the room together, we can use the formula: 1/rate = time.

The rate is the combined painting rate of both workers, which is equal to the sum of their individual painting rates.

Let's call the time it takes for Ermias and Manuel to paint the room together "T". The combined painting rate of both workers is then 1/T.

The individual painting rates of Ermias and Manuel are 1/8 hours per room and 1/6 hours per room, respectively. Therefore, their combined painting rate is 1/8 + 1/6 = 6/48 + 8/48 = 14/48 hours per room.

Now we can use the formula 1/rate = time to find T:

1/ (14/48) = T

48/14 = T

T = 3.43 hours

So it takes Ermias and Manuel 3.43 hours to paint the room if they are working together.
