Determine whether the table represents a linear or nonlinear function.
Answer:
Linear Function
Step-by-step explanation:
A linear function has constant slope
That means the ratio of y differences to x differences must be the same throughout the function. In other words the rate of change of the function y value is the same throughout the function
IF we look at the table we see that as x increases by 1, y decreases by 15
For example at x = 0, y = 20 and at x = 1, y = 5
So change in y/change in x = 0 = (5-20)/(1-0) = -15/1 = -15
If we look at another pair of points, say x = 1, y=5 and x = 2, y = -10
we get the rate of change = (-10 - 5)/(2-1) = -15/1 = -15
This is the same for any two x, y pair of values
So it is a linear function
WHAT IF? You need a mean score of at least 85 points to advance to the next round of the touch-screen trivia game.
A banner titled, Trivia Challenge shows your scores. The score with remarks are as follows. Game 1: 95, Very impressive. Game 2: 91, Good job. Game 3: 77, You can do better. Game 4: 89, Nice work.
Which scores in the fifth game will allow you to advance?
The mean score in the fifth game that will allow you to advance is 73.
What is the mean score that will allow you to advance?
The mean score in the fifth game that will allow you to advance can be gotten this way:
Assign the mean score, the variable, and x.
Compute the scores with remarks as follows:
95 + 91 + 77 + 89 + x ≥ 85
5
352 + x ≥ 85
5
85 × 5 = 425
352 + x ≥ 425
x = 425 - 352
x = 73.
So, the score in the fifth game that will allow you to advance will be 73.

The Marianas Trench in the Pacific Ocean is the deepest part of the ocean. It's depth is 6.85 miles. Sound
travels 4700 feet in one second under water. Find the time, to the nearest tenth of a second, it takes sound to
travel from the surface of the ocean to the bottom of the Marianas Trench and back.
6.85 miles is how deep it is. Under water, sound may travel 4700 feet in a second. The Time takes to travel the sound is 7.69.
Given that,
The deepest area in the ocean is the Marianas Trench in the Pacific Ocean. 6.85 miles is how deep it is. Under water, sound may travel 4700 feet in a second.
We have to calculate the time it takes for sound to travel from the ocean's surface to the Marianas Trench's depths and back, to the nearest tenth of a second.
We know the Distance formula is
Distance =rate×times
Time=Distance/rate
We convert 4700 feet to miles
We get,
4700 feet =0.89 miles
Now,
Time=6.85/0.89
Time=7.69
Therefore, the Time takes to travel the sound is 7.69.

Since the microwave raises the temperature of water by about 80°F in 5 minutes, the graph that has the slope that represents this rate of increase is option A.
What is the temperature about?
Temperature is seen as a given unit used to stand for hotness as well as the coolness of a given object or thing, it is said to be mostly in Fahrenheit as well as Celsius.
Based on temperature, heat energy is one that tends to shift from a hotter part of a body to a colder part of the same body.
Note that:
Temperature = 80
Minutes = 5
Y = m
5m = 80
m = 80/5
m = 16

Explain how you can represent a proportional relationship using an equation.
The proportional relationship can be represented by using an equation y = kx
Proportional relationship defined as the relationships between two variables where their ratios are equivalent. We can say that , in a proportional relationship, one variable is always a constant value times the other. That constant is called as the "constant of proportionality"
Consider y and x are in direct proportional relationship
y ∝ x
We can write this proportional relationship as
y = kx
Where y and x are the two variables
K is the constant of proportionality
In this equation we can see that the variable y is a constant value times the other variable x
Hence, the proportional relationship can be represented by using an equation y = kx

A quantitative expression, rule, or law that describes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions occur widespread, and they are essential for defining physical links in the sciences.A function is a type of rule that generates one output for a single output. This is represented by the equation y=x2. Any inputs for x result in an output for y.

[tex]e^{-5 \lambda}[/tex] is the probability that we have to wait for more than 5 min for the bus to arrive.
What probability exactly is?Mathematical representations of the likelihood that an event will occur or that a statement is true are dealt with in the area of probability.A number between 0 and 1, where 0 roughly denotes impossibility and 1 roughly denotes certainty, is the probability of an event.Axiomatic, classical, empirical, and subjective are the four most popular approaches to probability.So, [tex]f_X(x)=\lambda e^{-\lambda x}, x \geq 0[/tex] ⇒ [tex]P(x \geq 5)=\int_5^{\infty} f_X(x) d x[/tex]
Now, solving the above function as follows:

A wireless carrier offers the following plans that a person is considering.
The Family Plan: $90 monthly fee, unlimited talk and text on up to 8 lines, and data charges of $40 for each device.
The Mobile Share Plan: $120 monthly fee for up to 10 devices, unlimited talk and text for all the lines, and data charges of $35 for each device.
Use P for the number of devices that need data plans as part of their cost.
Find the model of the total cost of the Family Plan.
Find the model of the total cost of the Mobile Share Plan.
Assuming they stay under their data limit, find the number of devices that would make the two plans equal in cost.
If a family has 3 smart phones, which plan is more affordable?
Using linear functions, it is found that:
The model of the total cost of the Family Plan is: F(P) = 90 + 40P.The model of the total cost of the Mobile Share Plan is: M(P) = 120 + 35P.The costs will be the same for 6 devices.For 3 smartphones, the Family Plan is more affordable.What is a linear function in slope-intercept format, and why it is used in this problem?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).In the context of this problem, it is used because the rate of change for each plan is constant, that is, for each device, there is a constant increase in the plan charge.
For the plans in this problem, we have that:
The intercept is given by the monthly fee.The slope is given by the charges for each device.Hence the models for each plan are given as follows, with P representing the number of devices.
Family Plan: F(P) = 90 + 40P.Mobile Share Plan: M(P) = 120 + 35P.The costs will be the same when:
F(P) = M(P)
Hence we solve for P to find the number of plans as follows:
90 + 40P = 120 + 35P
5P = 30
P = 6 devices.
For 3 smartphones, the costs are given as follows:
F(3) = 90 + 40(3) = 210.M(3) = 120 + 35(3) = 225.210 < 225, hence the Family Plan is more affordable.

statements.

The number of centers that will be needed to contain the guests is 5.
How to calculate the value?It should be noted that the question isn't well written but will be answered based on the information given.
From the information, a space center can have at most 7 guests and there are 31 guests. In this case, the number of space centers needed will be calculated by dividing the number of guests by the numbers that are contained in each center.
This will be:
= Number of guests / Number contained by each center
= 31 / 7
= 4 3/7
In this case, since there's a remainder of 3, this implies that we will need an extra space center. Therefore,the total space centre will be:
= 4 + 1
= 5
In this case, the value of 5 that's gotten simply shows the number of space centers that will be needed.
