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.

Option A. 57. Roman numerals use letters from the Latin alphabet to represent numbers. The Roman numeral LVII represents the number 57.

The basic symbols used in the Roman numeral system are I, V, X, L, C, D, and M, which represent the numbers 1, 5, 10, 50, 100, 500, and 1,000, respectively. By combining these symbols, larger numbers can be formed.

In the case of LVII, the symbol L represents 50, the symbol V represents 5, and the symbol II represents 2. To get the total value of the Roman numeral, we add up the values represented by each symbol. So:

LVII = L + V + II

= 50 + 5 + 2

= 57

Therefore, the Roman numeral LVII represents the number 57.

The inverse of the given function could be; y = √x / 7 + 8

Suppose that the given function is [tex]f:X\rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

[tex]f^{-1}: Y \rightarrow X[/tex]

This simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'

We have been given the function as g(x)=7(x-8)² +3 for 8 ≤ x < ∝

Function that can reverse into another function is known as an inverse function or anti function to find y when x is swapped with another variable, we must first determine the inverse function.

Rory's product is less than Maranda's because 13/9 is less than 13/3

In mathematics, a fraction represents a part of a whole. A fraction consists of two numbers separated by a horizontal line called a fraction bar or a division sign. The number above the bar is called the numerator, and the number below the bar is called the denominator.

The numerator represents the number of parts being considered, while the denominator represents the total number of parts in the whole. For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator. This fraction represents three parts out of a total of four equal parts.

Fractions can be written in different forms, such as proper fractions, improper fractions, and mixed numbers.

A proper fraction has a smaller numerator than the denominator, such as 2/3 or 5/8.

An improper fraction has a numerator that is equal to or greater than the denominator, such as 7/4 or 11/6.

A mixed number consists of a whole number and a proper fraction, such as 2 1/3 or 3 2/5.

Fractions are used in many real-life situations, such as cooking, measuring, and financial calculations. They are also an essential part of mathematics and are used in operations such as addition, subtraction, multiplication, and division.

From the table, it appears that Maranda multiplied 4 1/3 by 4 1/3 and then by 1/3, while Rory multiplied 4 1/3 by 1/3 and then by 4 1/3.

Multiplying by 1/3 first reduces the overall size of the number being multiplied, resulting in a smaller product. This is what Rory did, which is why their product is less than Maranda's.

On the other hand, Maranda multiplied by the larger numbers first and then by the smaller fraction, resulting in a larger overall product.

Using the exponential function[tex]A(t) = 234(2.55)^t-[/tex]

There were approximately 1522 public electric charging units available in 2007.

There were approximately 9894 public electric charging units available in 2009.

There were approximately 25230 public electric charging units available in 2010.

The formula for an exponential function is [tex]f(x) = a^x,[/tex]where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

The exponential function is [tex]A(t) = 234(2.55)^t.[/tex]

Use the formula [tex]A(t) = 234(2.55)^t[/tex] to find the number of public electric charging units available for hybrid vehicles in a given year.

To find the number of outlets available in 2007, substitute t = 2 (since 2007 is two years after 2005) into the formula -

[tex]A(2) = 234(2.55)^2[/tex]

A(2) = 234(6.5025)

A(2) ≈ 1521.59

Therefore, the number of electric vehicles is 1522.

To find the number of outlets available in 2009, substitute t = 4 (since 2009 is four years after 2005) into the formula -

[tex]A(4) = 234(2.55)^4[/tex]

A(4) = 234(42.2825062)

A(4) ≈ 9894.10

Therefore, the number of electric vehicles is 9894.

To find the number of outlets available in 2010, substitute t = 5 (since 2010 is five years after 2005) into the formula -

[tex]A(5) = 234(2.55)^5[/tex]

A(5) = 234(107.820391)

A(5) ≈ 25229.97

Therefore, the number of electric vehicles is 25230.

The correct statements are (a) and (d). which are the graph is reflected over the x - axis and the the graph is shifted down 1 unit.

a. The graph is reflected over the x-axis.

This statement is true. The negative sign in front of the sine function reflects the graph of the parent function over the x-axis.

b. The frequency decreases by a factor of 1/4.

This statement is false. The coefficient in front of the x in the sine function determines the frequency of the wave. Since there is no coefficient in front of x in this case, the frequency of the wave remains the same.

c. The phase shift is 1/4 unit to the right.

This statement is false. The phase shift determines how the graph is horizontally shifted left or right. However, there is no horizontal shift in this case, so the phase shift is 0.

d. The graph is shifted down 1 unit.

This statement is true. The negative sign in front of the sine function also shifts the graph down by 1 unit.

e. The graph is reflected over the y-axis.

This statement is false. A reflection over the y-axis would require a negative sign in front of x, not in front of the sine function.

f. The frequency increases by a factor of 4.

This statement is false. As mentioned in (b), there is no change in frequency in this case.

Therefore, the correct statements are (a) and (d).

Answer: Malcolm can read 25 pages in 1 hour if he maintains the same reading speed.

Step-by-step explanation:

First, let's calculate how many pages Malcolm can read in 1 minute:

5 pages / 12 minutes = 0.4167 pages per minute (rounded to four decimal places)

To find out how many pages Malcolm can read in 1 hour, we need to multiply the number of pages he can read in 1 minute by the number of minutes in an hour:

0.4167 pages per minute * 60 minutes per hour = 25 pages per hour (rounded to the nearest whole number)

Therefore, Malcolm can read 25 pages in 1 hour if he maintains the same reading speed.

Answer: C. $725

Step-by-step explanation: To find the answer, let's first calculate the increase. A 16% increase causes the cost to go up by 16% of its own value, so let's calculate that by doing 0.16 x 12.5, giving us 2. Next, we add 2 to 12.50, giving us 14.5. Finally, we multiply 14.5 by 50 to find the cost for 50 students, giving us $725. So, $725 is our answer.

the unit rate for cranberries is $3 per pound.

How did we get?

The unit rate for raisins is the cost per pound. Since the cost for x pounds of raisins is y=2.5x, the unit rate for raisins is:

$$\frac{y}{x}=\frac{2.5x}{x}=2.5$$

Therefore, the unit rate for raisins is $2.5 per pound.

The unit rate for cranberries is also the cost per pound. Since the cost for 4 pounds of dried cranberries is $12, the unit rate for cranberries is:

$$\frac{\text{cost}}{\text{quantity}}=\frac{12}{4}=3$$

Therefore, the unit rate for cranberries is $3 per pound.

Therefore , the solution of the given problem of probability comes out to be P(not same color) = 236/361.

Calculating the likelihood that a statement is true or that an event will take place is the focus of probability theory, a branch of mathematics. Any number range between 0 and 1, where 1 is frequently used to describe certainty and 0 is commonly used to denote possibility, can be used to represent chance. A probability diagram shows the likelihood that a particular event will occur.

Here,

There are three cases to consider:

Case 1: both marbles are red

Case 2: both marbles are yellow

Case 3: both marbles are blue

The probability of drawing two red marbles can be found by multiplying the probability of drawing a red marble on the first draw (5/19) by the probability of drawing a red marble on the second draw (5/19):

P(red and red) = (5/19) * (5/19) = 25/361

Similarly, the probability of drawing two yellow marbles is:

P(yellow and yellow) = (6/19) * (6/19) = 36/361

And the probability of drawing two blue marbles is:

P(blue and blue) = (8/19) * (8/19) = 64/361

So, the probability of drawing two marbles that are the same color is:

P(same color) = P(red and red) + P(yellow and yellow) + P(blue and blue)

P(same color) = (25/361) + (36/361) + (64/361)

P(same color) = 125/361

d. If two marbles are drawn, what's the chance they are NOT the same color?

There are three cases to consider:

Case 1: one marble is red and one marble is yellow

Case 2: one marble is red and one marble is blue

Case 3: one marble is yellow and one marble is blue

The probability of drawing one red marble and one yellow marble can be found by multiplying the probability of drawing a red marble on the first draw (5/19) by the probability of drawing a yellow marble on the second draw (6/19), and then multiplying by 2 (since the order of the marbles doesn't matter):

P(red and yellow) = 2 * (5/19) * (6/19) = 60/361

Similarly, the probability of drawing one red marble and one blue marble is:

P(red and blue) = 2 * (5/19) * (8/19) = 80/361

And the probability of drawing one yellow marble and one blue marble is:

P(yellow and blue) = 2 * (6/19) * (8/19) = 96/361

So, the probability of drawing two marbles that are not the same color is:

P(not same color) = P(red and yellow) + P(red and blue) + P(yellow and blue)

P(not same color) = (60/361) + (80/361) + (96/361)

P(not same color) = 236/361

In observational studies, the variable of interest is not controlled.

The correct answer is D.

Observational studies are a type of research design used to investigate the relationship between variables. In an observational study, the researcher observes and records data without manipulating any variables. The variable of interest is the one that the researcher wants to investigate and understand its relationship with other variables.

Numerical variables are those that can be measured and expressed as numbers. Examples of numerical variables include age, weight, height, temperature, and income. These variables are important in observational studies because they can be analyzed quantitatively and compared to other variables of interest.

In contrast, categorical variables are not numerical, and they cannot be measured or expressed as numbers. Examples of categorical variables include gender, race, occupation, and marital status. These variables are not appropriate as the variable of interest in observational studies because they cannot be analyzed quantitatively.

In observational studies, the variable of interest is not controlled, meaning the researcher does not manipulate or control it. Instead, the researcher observes and records data on the variable and its relationship with other variables. This is in contrast to experimental studies, where the researcher manipulates one or more variables to observe their effect on another variable. Therefore the answer is D) is not controlled.
