What is frequency table?

A frequency table is a statistical tool used to organize data by counting the number of occurrences of each unique item or value in a dataset. It is a way to summarize and present data in a concise and structured manner, making it easier to understand and analyze.

For example, if you have a dataset of students' grades, you can create a frequency table by listing all the possible grades (e.g., A, B, C, D, F) and counting how many times each grade appears in the dataset. The resulting table will show the frequency or number of times each grade was earned by the students.

Frequency tables can be used to display both qualitative (categorical) and quantitative (numerical) data. For categorical data, the frequency table will show the count or percentage of occurrences of each category. For numerical data, the frequency table will show the number of times each value or range of values appears in the dataset

Based on the data you provided, here is a frequency table for the movie genres:

The GCF of 42 and 50 is 2.

The area of the figure is 51 cm², which is option C.

In mathematics, area refers to the measure of the size of a two-dimensional surface or shape. It is typically expressed in square units, such as square meters (m²) or square centimeters (cm²), and can be calculated for a variety of geometric shapes, including squares, rectangles, triangles, circles, and more complex shapes such as trapezoids or polygons.

To find the area of the figure, we need to identify the shape of the figure. From the given information, we know that the figure has a top side, a height, and a base. We are also told that the base is divided into two parts by a perpendicular, and one of the parts is labeled as 4 cm, while the other part from the perpendicular to the right vertex is 6.2 cm.

Based on this information, we can draw the figure as a trapezoid, where the top side is the shorter base, the height is the vertical distance between the two bases, and the longer base is the sum of the two parts of the base.

Using the given information, we can calculate the longer base:

longer base = 4 cm + 6.2 cm = 10.2 cm

Now we can use the formula for the area of a trapezoid to find the area of the figure:

A = (1/2)h(b₁ + b₂)

where h is the height, b₁ is the shorter base, and b₂ is the longer base.

Plugging in the given values, we get:

A = (1/2)(5 cm)(10.2 cm + 10.2 cm) = 51 cm²

Therefore, the area of the figure is 51 cm² , which is option C.

We can label the point (75, 50) as the optimal solution for the banquet, as it represents the maximum number of guests that can be invited while staying within the constraints.

What is banquet?

A banquet is a large formal meal that usually involves multiple courses and is served to a group of people on special occasions such as weddings, awards ceremonies, or fundraising events. Banquets often include speeches, presentations, and entertainment, and are typically held in a large venue such as a hotel ballroom, banquet hall, or conference center. Banquets can be hosted for a variety of purposes, such as to honor a special guest, celebrate an achievement, or raise money for a charitable cause.

To create a graph showing the solution region of the system of inequalities representing the constraints of the situation, we can use custom relationships to define the variables and constraints.

Let's define the variables:

Let x be the number of adult guests.

Let y be the number of student guests.

Now, let's write the system of inequalities representing the constraints of the situation:

The total number of guests cannot exceed 125: x + y ≤ 125

The cost of hosting the banquet cannot exceed $3375: 45x + 15y ≤ 3375

To graph this system of inequalities, we can plot the boundary lines of each inequality and shade the region that satisfies all the constraints.

The boundary lines of each inequality are:

x + y = 125 (the line that connects the points (0, 125) and (125, 0))

45x + 15y = 3375 (the line that connects the points (0, 225) and (75, 0))

To find the viable combinations of guests that satisfy all the constraints, we need to shade the region that is below the line x + y = 125 and to the left of the line 45x + 15y = 3375.

The resulting graph should look like this:

The point where the two lines intersect, (75, 50), represents the maximum number of adult guests (75) and the maximum number of student guests (50) that can be invited to the banquet while staying within the budget and venue capacity. Any point within the shaded region represents a viable combination of guests.

We can label the point (75, 50) as the optimal solution for the banquet, as it represents the maximum number of guests that can be invited while staying within the constraints.

Answer: To find the derivative of the function h(x), we can use the quotient rule, which states that if f(x) = u(x) / v(x), then f'(x) = [v(x)u'(x) - u(x)v'(x)] / [v(x)]^2.

Using this rule, we can find the derivative of h(x) as follows:

h(x) = (x + 2) / (x - 2)

h'(x) = [(x - 2)(1) - (x + 2)(1)] / (x - 2)^2 // apply the quotient rule and differentiate numerator and denominator

h'(x) = (-2 - 2x) / (x - 2)^2

Therefore, the derivative of h(x) is h'(x) = (-2 - 2x) / (x - 2)^2.

Step-by-step explanation:

The intersection points in the function is (-4, 61)

To find the intersection points of two functions, we can set them equal to each other and solve for x. Substituting x = -4, we have:

4(-4)² + 3(-4) + 3 = (-4)³ + 7(-4)² - 3(-4) + d

Simplifying, we get:

64 - 12 + 3 = -64 + 112 + 12 + d

The probability of both rolls being more than 4 is 0.25, written to two decimal places.

Probability is the measure of how likely it is that a certain event will occur. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur. Probability is calculated by taking the number of outcomes that are favorable to the event divided by the total number of possible outcomes.

Let X1 be the outcome of the first roll and X2 be the outcome of the second roll.
We want the probability that X1 > 4 and X2 > 4.
Since each of the 6 outcomes are equally likely and the two rolls are independent of each other, we can calculate the probability as the product of the probabilities of each event.
The probability of X1 > 4 is 3/6, and the probability of X2 > 4 is also 3/6.
Therefore, the probability that both rolls are more than 4 is:
P(X1 > 4 and X2 > 4) = (3/6) * (3/6) = 0.25

What are fractions?

A fraction is a mathematical representation of a quantity that expresses a part of a whole or a ratio between two quantities.

To find the total fraction of the diagram that is shaded, we need to add the fractions representing the shaded areas of the two squares.

Given that one square is shaded 2/12 and the other shaded square is 2/15, we can add these fractions:

2/12 + 2/15

To add fractions, we need to find a common denominator. The least common multiple (LCM) of 12 and 15 is 60, so we can use 60 as the common denominator for both fractions:

(2/12) + (2/15) = (2/12) * (5/5) + (2/15) * (4/4)

= 10/60 + 8/60

Now we can add the numerators:

= (10 + 8)/60

= 18/60

= 3/10

So, the total fraction of the diagram that is shaded is 3/10.

The two middle terms, -11w and +11w, cancel each other out, leaving only the first and last terms. This is why there is no middle term with a variable in the factorization of the difference of squares pattern.

When expanding a binomial expression in the form of (a + b)ⁿ, the middle term can be found using the following formula:

Middle term coefficient = nC(k), where k = (n+1)/2 if n is odd, and k = n/2 or (n/2 + 1) if n is even. The middle term coefficient is then multiplied by the product of a raised to the power of (n-k) and b raised to the power of k.

The difference of squares pattern is a special algebraic pattern that arises when we factor a polynomial that is the difference between two perfect squares. For example,

x² - y² = (x+y)(x-y)

When we apply this pattern to the expression w - 121, we can rewrite it as:

w² - 11²

And, we can use the difference of squares pattern to factor it as:

(w + 11)(w - 11)

Notice that there is no middle term with a variable in this factorization. This is because when we multiply (w + 11)(w - 11), the middle term cancels out.

To see why this happens, let's expand the product:

(w + 11)(w - 11) = w² - 11w + 11w - 121

The two middle terms, -11w and +11w, cancel each other out, leaving only the first and last terms. This is why there is no middle term with a variable in the factorization of the difference of squares pattern.

The radius of the circle is 12, and the equation of the circle is:

(x + 2)² + (y - 8)² = 144

What is a circle?

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

To find the equation of a circle that is tangent to a horizontal line at a given point, we can use the standard form of the equation of a circle:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and r is the radius.

In this case, the center of the circle is (-2, 8), which gives us:

(x + 2)² + (y - 8)² = r²

To find the radius, we need to know where the circle intersects the y = -4 line. Since the circle is tangent to the line, the distance from the center of the circle to the line is equal to the radius.

The distance between a point (x, y) and a horizontal line y = k is given by |y - k|.

In this case, the distance between the center (-2, 8) and the line y = -4 is |8 - (-4)| = 12.

Therefore, the radius of the circle is 12, and the equation of the circle is:

To calculate the variance of complaints received per week, we first need to find the mean or expected value of the number of complaints. This can be calculated by multiplying the number of complaints in each category by its corresponding probability, and then adding up the results.

Expected value = (0 x 0.13) + (1 x 0.21) + (2 x 0.44) + (3 x 0.07) + (4 x 0.06) + (5 x 0.09) = 2.54

Next, we can use the following formula to calculate the variance:

Variance = Σ[(x - µ)²P(x)]

where Σ = sum, x = number of complaints, µ = expected value, and P(x) = probability.

Using this formula and the probabilities given in the table, we get:

Variance = (0 - 2.54)²(0.13) + (1 - 2.54)²(0.21) + (2 - 2.54)²(0.44) + (3 - 2.54)²(0.07) + (4 - 2.54)²(0.06) + (5 - 2.54)²(0.09) = 1.4856

Rounding this answer to the nearest hundredth, we get a variance of 1.49.

In conclusion, the variance of complaints received per week is 1.49, meaning that the number of complaints is quite spread out around the mean, which is 2.54. This could indicate that the department store has some variability in its service quality, as the number of complaints can vary widely from week to week.
