In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x).Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).
What are a relationship's domain and range?
The collection of all conceivable independent values that a function or relation may take is known as its domain.It is the compilation of every potential input.The collection of all potential dependent values that a function or relation can generate from its domain values is known as its range. Graphs can be used as another tool for determining the domain and range of functions.The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values.The various output values are represented on the y-axis as the range.
Each given relation's scope and domain are as follows:
1. Range: 0.0, 0.5, 1.0,1.5,2.0 Domain: -10,-5,o,5,10
The symbol for a pair of relationship values is (x, y).All x-values make up the domain of a relation.The range includes all y-values.As a result, each relation's domain and range are as follows:
Domain -10,-5,o,5,10
Range 0.0, 0.5, 1.0,1.5,2.0

Answers
Using the t-distribution, it is found that:
a. The margin of error is of $122.4.
b. The 95% confidence interval for the population mean amount spent on restaurants and carryout food is of ($1,750.6, $1,995.4).
c. The estimate is the sample mean of $1,873.
What is a t-distribution confidence interval?The bounds of the confidence interval are given according to the following rule:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which the parameters are described as follows:
[tex]\overline{x}[/tex] is the sample mean, which is also the estimate of the population mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.In the context of this problem, the values of these parameters are given by:
[tex]\overline{x} = 1873, s = 550, n = 80[/tex]
Hence, for item c, the estimate is of $1,873, as it is the sample mean.
The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 80 - 1 = 79 df, is t = 1.9905.
The margin of error is given by:
[tex]M = t\frac{s}{\sqrt{n}}[/tex]
Hence:
[tex]M = 1.9905\frac{550}{\sqrt{80}} = 122.4[/tex]
The confidence interval is the sample mean plus/minus the margin of error, hence:
1873 - 122.4 = $1,750.6.1873 + 122.4 = $1,995.4.What is the missing information?The problem is given by the image at the end of the answer.

Answers
Answer:
Ryan had 10.20 dollars and Jeffery had 11.40 dollars.
Step-by-step explanation:
Let Ryan have x dollars originally, then Jeffrey has x + 1.20 dollars.
From the given info:
After getting 7.50 from Ryan, Jeffrey has:
x + 1.2 + 7.5 dollars and Ryan has x - 7.50 dollars.
Jeffreys money is now is 7 times as much as Ryan's, so:
x + 8.7 = 7(x - 7.5)
x + 8.7 = 7x - 52.5
8.7 + 52.5 = 7x - x
6x = 61.2
x = 10.20 dollars.

Each gallon of water weighs by itself is 8.4 pounds, option (C) 8.4 pounds is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
From the data given:
When the Amount of Water in Can (gallons) = 0
Weight of Cans (pounds) = 2
It means the weight of the can = 2 pounds
For the 0.5 gallons, the weight of the can = 6.2 pounds
For the 0.5 gallons, the weight of the water = 6.2 - 2 = 4.2 pounds
For the 1 gallon, the weight of the water = 2x4.2 pounds
= 8.4 pounds
Thus, each gallon of water weighs by itself is 8.4 pounds, option (C) 8.4 pounds is correct.

One angle measures 170°, and another angle measures (6k + 44)°. If the angles are vertical angles, determine the value of k.
Answers
Answer:
21 = k
Step-by-step explanation:
Vertical angles are equal
170 = 6k+44
Subtract 44 from each side
170-44 = 6k+44-44
126 = 6k
Divide each side by 6
126/6 = 6k/6
21 = k

(a) The expression to represent the length of the rectangle is

(b) The length of the rectangular prism is L = ((7/x)-(3/5x))/(2/x)(4/x).
What is a rectangle?A rectangle is a quadrilateral with all four interior angles measures of 90°.
(a) Given that, the area of the rectangle is x-16/x and its width is x/4 +1.
Let the length of the rectangle be h, then it follows:
h×(x/4 + 1) = x - 16/x
h = (x-16/x)/(x/4+1)
Hence, the expression to represent the length of the rectangle is
h = (x-16/x)/(x/4+1).
(b) Given that, the volume of the rectangular prism is (7/x)-(3/5x), the width is 2/x, and the height is 4/x.
Let the length of the rectangular prism be L, then it follows:
L× (2/x) ×(4/x) = (7/x)-(3/5x)
L = ((7/x)-(3/5x))/(2/x)(4/x)
Hence, the length of the rectangular prism is L = ((7/x)-(3/5x))/(2/x)(4/x).

State if the three numbers can be the measures of the sides of a triangle. 1) 9, 7, 13 2) 26, 12, 11 3) 11, 2,9 4) 6, 11, 12 Two sides of a triangle have the following measures. Find the range of possible measures for the third side. 5) 12,9 7) 11,6 6) 8, 11 8) 12,8
Answers
To determine if the three numbers can be the measures of the sides of a triangle:
According to the Triangle Inequality theorem to construct a triangle, the sum of the two sides of the triangle is greater than the third side i.e x + y>z
1) 9, 7, 13
So, 9+7 > 13
16 > 13
7+ 13 > 9
20 > 9
9+13 > 7
22 > 7
Yes, they can be the measures of the sides of a triangle.
2) 26, 12, 11
So, 26+12 > 11
38 > 11
12+ 11 > 26
23 < 26
No, they cannot be the measures of the sides of a triangle.
3) 11, 2,9
So, 11+2 > 9
13 > 9
2+ 9 > 11
11 = 11
No, they cannot be the measures of the sides of a triangle.
4) 6, 11, 12
So, 11+6 > 12
17 > 9
11+12 > 6 and 12+6 > 11
Yes, they can be the measures of the sides of a triangle.
To determine the range of the third side we find the maximum value and minimum value using two sides of a triangle.
Let's assume that x is the third side of the triangle.
5) 12,9
So, the maximum value of the third side is 12+9 = 21 and the minimum value is 12-9 = 3.
Hence, the range is 3<x<21.
6) 8, 11
The maximum value of the third side is 8+11 = 19 and the minimum value is 11-8 = 7.
Hence, the range is 3<x<19.
7) 11,6
The maximum value of the third side is 11+6 = 17 and the minimum value is 11-6 = 5.
Hence, the range is 5<x<17.
8) 12,8
The maximum value of the third side is 12+8 = 20 and the minimum value is 12-8 = 4.
Hence, the range is 4<x<20.

Answers
Based on the information that the smallest score in a population is x=5, and the largest score is x=10, the conclusion is that the standard deviation is going to be smaller than the range of scores.
Given that in a population, the smallest score is x=5, and largest score is x=10, the range of scores is:
Range of scores=largest score-lowest score
=10-5
=5
Here the range of scores is 5, and the mean of the scores is likely to be between 5 and 10
Standard deviation which refers to the average spread of the distribution, will now be considered to be smaller since the range of scores is low.
Because standard deviation is found from the mean, if the mean is between x=5 and x=10, the standard deviation must be lower than x=5.
Hence, smaller than the range of scores.

The line shown in the graph have slope of line as 13/27 with rise 13 and run 27.
What is slope of line?
The definition of slope in mathematics is pretty close to how we normally define it. Slope is a mathematical term used to indicate a line's steepness and direction. A line's slope can be inferred from its graph alone, especially in comparison to other lines shown on the same coordinate plane.
The formula to calculate the slope of any line is given by:
[tex]slope = \frac{rise}{run}[/tex]
We know that, '
rise = y₂ - y₁
run = x₂ - x₁
As we can see in the graph
x₂ = 10, y₂ = 3
x₁ = -7, y₁ = -10
putting the values in above formula
rise = y₂ - y₁ = 3 -(-10) = 13
run = x₂ - x₁ = 10 -(17) = 27
so, slope = 13/27
Hence the slope of the line shown in graph is 13/27.
