Answer:
No, because for each input there is not exactly one output
Step-by-step explanation:
Each input, x-coordinate, must have one and only one output (y-coordinate) to be a function.
Since 3/4 is used as an x-coordinate twice, the input 3/4 has two different outputs, -2 and -1/2. That means this relation is not a function.

The scale on a map is 5 centimeters = 75 kilometers. Two lakes on the map are located 8.1 cm apart. What is the actual distance between the two lakes?
Answers
5 cm / 75 km = 1 cm / x km
Cross-multiplying, we get:
5x = 75
Dividing both sides by 5, we get:
x = 15
So, 1 centimeter on the map corresponds to 15 kilometers in real life.
Now, we can use this information to find the actual distance between the two lakes. We know that they are located 8.1 cm apart on the map, so:
8.1 cm * 15 km/cm = 121.5 km
Therefore, the actual distance between the two lakes is 121.5 kilometers.
Answer:
If 5 centimeters on the map represent 75 kilometers in the real world, then we can use proportion to find the actual distance between the two lakes.
Let x be the actual distance between the two lakes in kilometers. Then we can set up the following proportion:
5 cm / 75 km = 8.1 cm / x km
To solve for x, we can cross-multiply:
5 cm * x km = 75 km * 8.1 cm
Simplifying:
5x = 607.5
x = 121.5 km
Therefore, the actual distance between the two lakes is 121.5 kilometers.
You are decorating a parade float for a Cinco de Mayo parade. The area of the entire parade float is 192 square feet.
What is the area covered by paper flowers?
9 ft (x+12) ft x ft 5 ft
The area covered by paper flowers is square feet.
Answers
The area covered by paper flowers is; 45 square feet.
How to find the area of the rectangle?The formula for area of a rectangle is;
Area = Length * width
Parameters of the parade float are;
Length = 9 + x + 12 = (x + 21) ft
Width = (x + 5) ft
Since entire area is 192 sq.ft, then;
(x + 5)(x + 21) = 192
x² + 5x + 21x + 105 = 192
x² + 26x - 87 = 0
Using online quadratic equation calculator gives;
x = 3
Thus;
Length of paper flower = x + 12 = 3 + 12 = 15 ft
Width of paper flower = 3 ft
Area of paper flowers = 15 * 3 = 45 square feet.

The amount of time it would take for Mr. Smith's rocket to return to the ground is 8 seconds.
How to determine the time when the rocket would hit the ground?Based on the information provided, we can logically deduce that the height (h) in meters, of this rocket above the ground is related to time by the following quadratic function:
h(t) = -16t² + 128t
Generally speaking, the height of this rocket would be equal to zero (0) when it hits the ground. Therefore, we would equate the height function to zero (0) as follows:
0 = -16t² + 128t
16t² = 128t
16t = 128

If the experiment is repeated 140 times, the number of times both spins will be odd numbers, 35.
What is probability?Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.
Probability of Event = Favorable Outcomes/Total Outcomes = X/n
The theoretical probability of both spins being odd numbers is 9/36.
This means that, if the spinner was spun an infinite number of times, 9 out of every 36 spins would result in both spins being odd numbers.
In the repeated experiment, Ryan spun the spinner 140 times.
This means that, based on the theoretical probability, we can expect the number of times both spins will be odd numbers to be approximately
= 140 x 9/36

How to calculate coefficient of variation?
Answers
Answer:
Step-by-step explanation:
The coefficient of variation (CV) is a measure of the relative variability of a set of data. It is calculated as the ratio of the standard deviation to the mean, expressed as a percentage. The formula for calculating the CV is as follows:
CV = (Standard Deviation / Mean) * 100%
Here's how to calculate the CV step by step:
Calculate the mean: To find the mean, add up all the data points and divide by the number of data points. This will give you the average value of the data set.
Calculate the standard deviation: The standard deviation is a measure of the variability of a set of data. To calculate it, subtract each data point from the mean and square the result. Then add up the squared deviations and divide by the number of data points minus one. Finally, take the square root of the result to obtain the standard deviation.
Calculate the CV: Finally, divide the standard deviation by the mean and multiply by 100% to obtain the CV.
The CV is a useful measure when comparing data sets with different units of measurement or when comparing the variability of data sets with different means. It gives an indication of the degree of variation in the data set relative to the mean, with higher CV values indicating a higher degree of variability.
It is important to note that the CV should not be used to compare data sets with very different means, as it can be misleading in such cases. In those cases, it is better to use the standard deviation or other measures of variability.

Answers
As a result of answering the question, we may state that triangle Because of this, AB is longer than 33. But since we don't know the precise angle at B, we can't be positive of its length.
What precisely is a triangle?Since a triangle has four or so more sections, it is a polygon. It has an easy rectangular form. Triangle ABC refers to a rectangle with edges A, B, and C. A single plane and cube are produced by Euclidean geometry when the sides are really not collinear. A triangle is a polygon if it has 3 components and three angles. Where a triangle's three edges come together are known as the corners. A triangle's sides add up to 180 degrees.
A+B plus D > A (1)
Applying this to triangle ADC, we get the following:
A + C > A (2)
AC equals 27, CD equals 9, and BD equals 3. Equation (2) may be used to determine AD:
[tex]A + C > A\\27 + 9 > AD\\36 > AD[/tex]
So, we are aware that AD is lower than 36. We may now find AB using equation (1):
[tex]A+B plus D > A\\AB + 3 > AD\\AB + 3 > 36\\AB > 33[/tex]
Because of this, AB is longer than 33. But since we don't know the precise angle at B, we can't be positive of its length.

The top of a square coffee table has an area of
64x48x + 9. What is the perimeter of the
tabletop?
Answers
Area = side^2
We are given the area of the tabletop as 64x48x + 9, so we can set up the following equation:
64x48x + 9 = side^2
Simplifying the left-hand side:
64x48x + 9 = (8x6x)^2 + 3^2
64x48x + 9 = 36^2 + 3^2
64x48x + 9 = 1296 + 9
64x48x = 1296
Dividing both sides by 64x48:
side^2 = 27
Taking the square root of both sides, we get:
side = sqrt(27)
Now we know the length of one side of the square tabletop, and since all sides are equal, the perimeter is:
Perimeter = 4 x side
Perimeter = 4 x sqrt(27)
Perimeter = 4 x 3sqrt(3)
Perimeter = 12sqrt(3)
Therefore, the perimeter of the tabletop is 12sqrt(3) units.

A juice drink contains 100 oz of concentrated juice and water, and is 28%
concentrated juice. If the drink is to be weakened to 20%, how much water must be added?
Actually answer. I will, and have, reported for people faking the asnwer or not answering at all. Please.
Answers
Answer: We need to add 40 ounces of water to the 100 oz of concentrated juice and water to obtain a new mixture that is 20% concentrated juice.
Step-by-step explanation:
We can begin by setting up an equation based on the given information.
Let's say we need to add x ounces of water to the 100 oz of concentrated juice and water to obtain the new 20% mixture.
The amount of pure juice in the original 100 oz mixture is 28% of 100 oz, which is 0.28(100) = 28 oz.
After x ounces of water are added, the total volume of the mixture becomes 100 + x oz. The amount of pure juice remains the same at 28 oz. We want to find the amount of water that needs to be added to reach a concentration of 20%.
Setting up the equation:
0.20(100 + x) = 28
Expanding and simplifying:
20 + 0.20x = 28
0.20x = 8
x = 40
Answer:
143
Step-by-step explanation:
100 oz is 28 % of the drink
So total volume of the drink = 357 oz.
A drink that of 100 oz juice and is 20% juice has a volume of 500 oz.
So, we need to add 500 - 357
= 143 oz water.

You are going to use an incline plane to lift a heavy object to the top of a shelving unit with a height of 7 ft. The base of the incline plane is 11 ft from the shelving unit. What is the length of the incline plane?
Answers
Answer:
We can use the Pythagorean theorem to solve this problem. Let's call the length of the incline plane "L". We know that the height of the shelving unit is 7 ft and the base of the incline plane is 11 ft. The hypotenuse of the right triangle formed by the incline plane, the floor, and the shelving unit will be the length of the incline plane. Using the Pythagorean theorem:
L^2 = 11^2 + 7^2
L^2 = 121 + 49
L^2 = 170
L = sqrt(170)
So the length of the incline plane is approximately 13.04 feet.

Since g and h are parallel lines cut by the transversal i, we know that alternate interior angles are congruent. Therefore, the measurement of ∠1 is equal to the measurement of ∠3. We do not need to show any work to answer this question.
Since g and h are parallel lines cut by the transversal j, we can see that ∠3 and ∠5 are corresponding angles, and ∠5 and ∠6 are vertical angles. Therefore, ∠3 and ∠6 are congruent. Since ∠3 and ∠6 forms a linear pair, their sum is 180 degrees. Thus, we can set up an equation:
∠3 + ∠6 = 180
Substituting ∠6 for ∠3, we get:
∠3 + ∠3 = 180
Simplifying, we get:
2∠3 = 180
Dividing both sides by 2, we get:
∠3 = 90°
Therefore, the measurement of ∠3 is 90 degrees.
