Answer: Cost = $70 + ($13)(n)

Step-by-step explanation: As we can see that the cost of the banquet is 70$ and for each person attending there will be a 13$ extra so as to model this problem, let's from an expression. The expression that models the problem can be written as -

Cost = $70 + ($13)(n)

In this expression 'n' will be the number of people attending the banquet at that time.

In this expression the 'x' will be the number of people attending the banquet. 'y' will be the cost of the banquet. y-intercept will be 70$, which is actually the cost of the banquet and the slope will be 13$ which is the cost for each person that will be attending.

The relationship between the cup size and the cost is proportional and the constant of proportionality is 0.3.

At a restaurant, hot chocolate can be purchased in two different cup sizes. A 12-ounce cup costs $3.60 and a 16-ounce cup costs $4.80.

Let's find if the relationships of the variables are proportional.

proportional relationship are relationships between two variables where their ratios are equivalent.

Therefore, proportional relationship is rep[resented as follows:

y = kx

where

Hence,

3.6 = 12k

k = 3.6 / 12

k = 0.3

4.80 = 16k

k = 4.8 / 16

The Ferris wheel is 16.63 feet tall.

Angle of depression is the angle which is between a horizontal line and the line of sight which is pointed downwards.

We have a triangle formed here by the information given.

Angle of depression between the Ferris wheel and the friend on the ground = 61°

Distance of friend from the foot of the Ferris wheel = 30 feet

We have to calculate the height of Ferris wheel.

Let x be the required height.

tan 61 = 30 / x

x = 30 / tan 61

x = 30 / 1.804

x = 16.63 feet

Hence the height of the Ferris wheel is 16.63 feet.

The distribution of numerical data is roughly depicted by a histogram.

Karl Pearson was the person who first coined the phrase.

The first stage in creating a histogram is to "bin" (or "bucket") the range of values, divide 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, though not always, have the same size.

The equation for a parabola with a focus at (9, 0) and a directrix at y = -4 is y = (x - 9)^2 - 4.

Parabola is a type of curve that is symmetrical around a line called the directrix. It is an important conic section and is described by a quadratic equation.

This equation is derived from the equation for a parabola in standard form, which is y = a(x - h)^2 + k.
To find the equation for the parabola, we need to determine the values of a, h, and k. The focus of the parabola is (9, 0), so h = 9. The directrix of the parabola is y = -4, so k = -4. The value of a can be determined by the distance between the focus and the directrix, which is 4. So a = 1/4.
Putting these values together, we get y = (x - 9)^2 - 4.

How to subtract decimal numbers?

Subtracting decimals is similar to the usual subtraction of whole numbers. We just need to place the decimal numbers, one below the other, according to their place values along with the decimal point. In some cases the two given numbers are different. If needed, we change the given decimal fractions to like decimal fractions to make the subtraction easier. Two decimals are called decimal fractions if they have an equal number of decimal places.

Now, the weight of Desta's plum-the weight of Eddy’s plum=3.24-3.042

=0.198 ounce

Hence, Desta's plum weighs 0.198 ounces more than Eddy’s plum.

The equation for an exponential function is f(x) = [tex](ab)^{x}[/tex], where a and b are constants, and the value of f(12) is 1144.14.

An exponential function is one that raises the independent variable to a power. It is typically stated as f(x) = [tex]b^{x}[/tex], where b is the base and x is the exponent. Several real-world phenomena, such as population expansion, radioactive decay, and compound interest, are modelled using exponential functions.

The equation for an exponential function is f(x) = [tex](ab)^{x}[/tex], where a and b are constants.

Since we know that f(3.5) = 10 and f(9.5) = 30, we can solve for a and b.

We first need to solve for b. We can use the equation: b = f(x) / f(x-1)

So, b = 30 / 10 = 3

Now, we can solve for a. We can use the equation: a = f(x) / [tex]b^{x}[/tex]

So, a = 10 / [tex](3)^{3.5}[/tex] = 0.093

Now, we can plug in the values for a and b and x = 12 into our equation to find f(12).

f(12) = 0.093 * [tex]3^{12}[/tex] = 1144.14

Therefore, the value of f(12), to the nearest hundredth, is 1144.14.

Step-by-step explanation:

1) There were 1.26 times as many assaults in Year 5 compared to Year 1

2) Graph B best represents the data.

What is Graph?

A graph is a structure that resembles a set of items in discrete mathematics, more specifically in graph theory, in which some pairs of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Given that;

The data is most accurately depicted in bar graph B.

It allows for the following data observations:

In year 1, there were 235 assaults.

Year 1 saw 265 assaults, Year 2 saw 250 attacks, Year 1 saw 280 assaults, Year 1 saw 295 assaults, and Year 2 saw 260 assaults.

1)In the first year, there were 235 assaults, and by the fifth year, there were 295 assaults.

ratio = year5/year1 = 295/235 =1.26

Hence , there were 1.26 times as many assaults in Year 5 compared to Year 1

2) The total number of data points falls between 200 and 300.

Therefore, graph A, whose output value ranges from 0 to 300, is not truly necessary.

Graph B, on the other hand, uses the right range and has a step size of 10, which is also fairly accurate.

Therefore, Graph B best depicts the data.
