plot the x- intercept and y- intercept. then write the intercepts as ordered pairs
Answers
Answer:
x-intercept = 4
y-intercept = -1
As ordered pairs they would be ( 4, 0) and ( 0, -1)
Step-by-step explanation:
The line goes through 4 on the x line and goes through -1 on the y line.
As an ordered pair you just put the numbers in their x and y spots being ( x, y )
With 4 being on the X and -1 being on the Y it would make them ( 4, 0) and

For each of the following scenarios, determine whether the mean or median better represents the data (place a check mark in the appropriate box). For each case, explain why you chose that particular average. The following three scenarios below do not have a specific data set. Be sure to consider all possibilities/outcomes! "Create" a data set if you need to.
Answers
In each scenario, the choice between mean and median as a representative measure of central tendency depends on the nature of the data and the specific context..
1. Scenario: Income distribution of a population
- If the income distribution is skewed or contains extreme values (outliers), the median would be a better representation of the central tendency. This is because the median is not influenced by outliers and provides a more robust estimate of the "typical" income level. However, if the income distribution is approximately symmetric without outliers, the mean can also be an appropriate measure.
2. Scenario: Exam scores in a class
- If the exam scores are normally distributed without significant outliers, the mean would be a suitable measure as it takes into account the value of each score. However, if there are extreme scores that deviate from the majority of the data, the median may be a better representation. This is especially true if the outliers are indicative of errors or exceptional circumstances.
3. Scenario: Housing prices in a city
- In this case, the median would be a more appropriate measure to represent the central tendency of housing prices. This is because the housing market often exhibits a skewed distribution with a few high-priced properties (outliers). The median, being the middle value when the data is sorted, is not influenced by these extreme values and provides a better understanding of the typical housing price in the city.
Ultimately, the choice between mean and median depends on the specific characteristics of the data and the objective of the analysis. It is important to consider the distribution, presence of outliers, and the context in which the data is being interpreted.

Two race cars, Car Y and Car Y, are at the starting point of a 2-km track at the same
time. Car X and Car I make one lap every 60 s'and every 80 s respectively.
(a)
How long, in seconds, will it take for both cars to be back at the starting point
at the same time?
b)How long, in minutes, will it take for the faster car to be 5 laps ahead of the
slower car?
Answers
a). Both cars will be back at the starting point at the same time after
240 seconds.
b). The time difference between the two cars will be 100 seconds.
a). We need to find the time when both cars complete their 1st lap at the same time.
Time taken by Car X to complete 1 lap = 60 s.
Time taken by Car Y to complete 1 lap = 80 s.
Since both the cars start together, we just need to find the LCM of 60 s and 80 s.
The LCM of 60 s and 80 s is 240 s.
b). It will take the faster car 5 laps or 1 minute 40 seconds to be 5 laps ahead of the slower car.
The difference in time taken by the cars to complete 1 lap is 20 s
(80 s - 60 s).
After 5 laps, the time difference between the two cars will be 100 s
(20 s/lap × 5 laps), which is equal to 1 minute 40 seconds.

How to determine the vertex form of a quadratic function?In Mathematics, the vertex form of a quadratic function is represented by the following mathematical equation:
f(x) = a(x - h)² + k

h and k represents the vertex of the graph.a represents the leading coefficient.In order to write the given function in vertex form, we would have to apply completing the square method as follows;
f(x) = 8x² + 4x
f(x) = 8[x² + 0.5x]
f(x) = 8[x² + 0.5x + (0.5/2)² - (0.5/2)²]
f(x) = 8[(x² + 0.5x + 1/16) - 1/16]
f(x) = 8[(x + 0.25)² - 1/16]

A group of 47 children, with some adults, travelled by coach on a trip to a zoo.
The total cost of the trip was $591.

The cost of hiring the coach was $118
How many adults were there in the group?
You must show your working.
Answers
Answer:
5 adults
Step-by-step explanation:
plug in all numbers and calculate
The total cost of the trip is $591 and the cost of hiring the coach was $118. So now what you did is that you subtract $591-$118=$473.
For entrance fee was $8.75 per each child and there was a total of 47 children. Then multiply 47x8.75 and you get $411.25. And then subtract 473 by 411.25 and which will be 61.75. And then the cost of each adult is $12.35. Then you divide 61.75 by 12.35.
Then when you divide it and the answer should be 5.
Which means that the amount of adults inside the group was 5.

I need help creating an equation to match the table
Answers
Let x be "the number of hours worked"
And y be "Amount of money earned"
If both variables vary proportionality, you can say that the constat of proportionality is
\(k=\frac{y}{x}\)Choosing one pair of values of the table:
For example x=2 and y=125
Assuming the flat fee the painter changes is 25 (I choose it to be 25 because the variation turns proportional if you subtract 25 fromm all values of y)
Then subtract it from the value of y
125-25=100
And use it to calculate the the constant k
\(k=\frac{100}{2}=50\)So the painter earns $50 per hour worked
The function is then y=25+50x

Answer:
x = 23°
Step-by-step explanation:
Framing an equation and finding the unknown value:
Sum of all angles of a triangle = 180°
x + 3 + 5x - 8 + 2x + 1 = 180
x + 5x + 2x + 3 - 8 + 1 = 180
Combine like terms,
8x -4 = 180
Add 4 to both sides,
8x = 180 + 4
8x = 184
Divide both sides by 8,
x = 184÷8
x = 23°

Mr. Daniels is organizing a class trip. He wants to spend less than $300. Which inequality represents the cost, c, that Mr. Daniels can spend on the class trip?
c < 300
Answers
The inequality that represents the cost, c, that Mr. Daniels can spend on the class trip is; c < 300
How to solve Inequality word problems?
We are told that;
Mr. Daniels is organizing a class trip.
Mr. Daniels wants to spend less than $300
Thus, if the cost that Mr. Daniels can spend on the class trip is given as c, then it means that c has to be less than the amount which he wants to spend which is $300.
Thus, since c has to be less than $300, then it means that the inequality to be used would be a less than sign which can be expressed as;
c < 300
Thus, we conclude that it is the required inequality.

Given the following linear optimization problem Maximize 250x + 150y Subject to x + y ≤ 60 3x + y ≤ 90 2x+y>30 x, y 20 (a) Graph the constraints and determine the feasible region. (b) Find the coordinates of each corner point of the feasible region. (c) Determine the optimal solution and optimal objective function value.
Answers
The linear optimization problem is to maximize the objective function 250x + 150y, subject to the constraints x + y ≤ 60, 3x + y ≤ 90, and 2x + y > 30, where x and y are both greater than or equal to 20.
what is the feasible region and the optimal solution for the given linear optimization?The feasible region can be determined by graphing the constraints and finding the overlapping region that satisfies all the conditions. In this case, the feasible region is the area where the lines x + y = 60, 3x + y = 90, and 2x + y = 30 intersect. This region can be visually represented on a graph.
To find the corner points of the feasible region, we need to find the points of intersection of the lines that form the constraints. By solving the systems of equations, we can find that the corner points are (20, 40), (20, 60), and (30, 30).
The optimal solution and the optimal objective function value can be determined by evaluating the objective function at each corner point and selecting the point that yields the maximum value. By substituting the coordinates of the corner points into the objective function, we find that the maximum value is achieved at (20, 60) with an objective function value of 10,500.

A hemispherical tank is filled with water and has a diameter of 12 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?
Answers
Answer:
The total weight = 1286 × 62.4 = 80246 pounds.
Step-by-step explanation:
The formula of the volume of the sphere is
V = 4/3×π×r³
Given
d = 17 feet
d = 2r
r = d/2 = 17/2 = 8.5 feet
V = 4/3×π×r³
Since we need half of the volume as it is a hemispherical tank.
= 1286 ft³
Given that the weighs 62.4 pounds per cubic foot
Thus, the total weight = 1286 × 62.4 = 80246 pounds.
