Answer: If [tex]a=b[/tex] and [tex]b=c[/tex], then [tex]a=c[/tex]
Step-by-step explanation:
Let be "a", "b", and "c" all real numbers, the Transitive property of equalities states that :
If [tex]a=b[/tex] and [tex]b=c[/tex], then [tex]a=c[/tex]
You can observe that if two numbers are equal to the same number, then all this numbers are equal to each other.
For example, applying the Transitive property of equalities to:
[tex]x+3=5[/tex] and [tex]2x+1=5[/tex]
You can equate them:
[tex]x+3=2x+1[/tex]
And solve for "x":
[tex]3-1=2x-x\\\\x=2[/tex]
Answer:
The correct answer option is: If a = b and b = c, then a = c.
Step-by-step explanation:
The Transitive Property of Equality states that if one value, lets say [tex] a [/tex] is equal to another value, call it [tex] b [/tex], which is equal to another value, call it [tex] c [/tex], then the very first value [tex] a [/tex] would be equal to the third value [tex] c [/tex].
So from the given answer options, the correct option is: If a = b and b = c, then a = c.
What is the range of the data below?
22
28
41
42
Final answer:
The range of the data set (22, 28, 41, 42) is calculated by subtracting the smallest number from the largest, resulting in a range of 20.
Explanation:
The question asks for the range of a given data set. The range of a set of numbers is the difference between the largest and smallest numbers. In the provided list of numbers: 22, 28, 41, 42, the smallest value is 22 and the largest is 42.
To calculate the range, you subtract the smallest number from the largest number:
Range = Largest number - Smallest number
Range = 42 - 22
Range = 20
Therefore, the range of the data is 20.
Archie can buy 5 buckets of popcorn and 2 drinks for $16.25. Terry can buy 3 buckets of popcorn and 1 drinks for $9.50. Assume that all buckets of popcorn are the same price and all drinks are the same price.
Answer:
The cost of one bucket of popcorn is $2.75
The cost of one drink is $1.25
Step-by-step explanation:
Let
x ----> the cost of one bucket of popcorn
y ----> the cost of one drink
we know that
5x+2y=16.25 -----> equation A
3x+y=9.50
y=9.50-3x ----> equation B
Solve the system of equations by substitution
Substitute equation B in equation A and solve for x
5x+2(9.50-3x)=16.25
5x+19-6x=16.25
6x-5x=19-16.25
x=$2.75
Find the value of y
y=9.50-3x
y=9.50-3(2.75)=$1.25
therefore
The cost of one bucket of popcorn is $2.75
The cost of one drink is $1.25

What number is the same as 3 tens + 24 ones?
Answer:
54
Step-by-step explanation:
3 tens = 3*10 = 30
24 ones = 24*1 = 24
30+24 = 54
Final answer:
The number that represents 3 tens + 24 ones is 54. This is found by adding 30 (representing the 3 tens) to 24 (representing the 24 ones).
Explanation:
The number that is the same as 3 tens + 24 ones is calculated by first understanding what each term represents.
Three tens is equivalent to 30 because one ten equals 10 and 10 multiplied by 3 equals 30.
Twenty-four ones simply means 24 because one multiplied by 24 is 24.
Therefore, to find the number that represents 3 tens + 24 ones, we add 30 and 24 together.
30 (3 tens) + 24 (24 ones) = 54
So, the number that is the same as 3 tens + 24 ones is 54.

Find the exact value of sin15
The exact value of trigonometric function sin(15 degrees) is √6 - √2 divided by 4.
What is the exact value of sin15?To find the exact value of sin(15 degrees), we can use the sum-to-product trigonometric identity, which states that:
sin(A) + sin(B) = 2 × sin((A + B) / 2) × cos((A - B) / 2).
In this case, we can write sin(15) as sin(45 - 30) and use the identity.
First, we have sin(45 degrees) and sin(30 degrees), which are known values of √2/2 and 1/2, respectively. Plugging these values into the identity, we get sin(15) = 2 × sin(7.5) × cos(7.5).
Now, we can use the half-angle formulas for sine and cosine to simplify further. Sin(7.5 degrees) can be expressed as (√6 - √2) / 4, and cos(7.5 degrees) as (√6 + √2) / 4. So,
sin(15 degrees) = 2 × [(√6 - √2) / 4] × [(√6 + √2) / 4], which simplifies to (√6 - √2) / 4.
In conclusion, the exact value of sin(15 degrees) is (√6 - √2) / 4. This value can be derived using trigonometric identities and the half-angle formulas for sine and cosine.

Which of the following ordered pairs could be the y-intercept of a function? (1, 2) (-3, 2) (5, 0) (0, 0)
Answer:
(0, 0)
Step-by-step explanation:
The y-intercept refers to the point where the graph of a function intersects or crosses the y-axis. The value of x is usually zero at this particular point since the y-axis has the equation;
x = 0
From the alternatives given, the ordered pair (0, 0) could be the y-intercept of a function since x has a value of 0.

Are the graphs of the lines in the pair parallel? Explain. y = 6x + 9 27x – 3y = –81 No, since the y-intercepts are different. Yes, since the slopes are the same and the y-intercepts are different. No, since the slopes are different. Yes, since the slopes are the same and the y-intercepts are the same.
Answer:
No, since the slopes are different
Step-by-step explanation:
Parallel lines by definition have the same slope but different y-intercepts. The slope of the line y = 6x + 9 is 6, the coefficient of x since the equation is given in slope-intercept form. Its y-intercept is 9.
For the second equation, 27x – 3y = –81 , we have to solve for y or re-write the equation in slope-intercept form;
-3y = -27x - 81
y = 9x + 27
The slope of this line is thus 9, the coefficient of x since the equation is in slope-intercept form. Its y-intercept is 27.
The two equations have different slopes and thus they are not parallel
This the question complete the table below to show how to find the variance. After finding the variance, calculate the standard deviation
Answer:
Step-by-step explanation:ik
Final answer:
To find the variance, calculate the average of the squared differences between each data point and the mean. The standard deviation is found by taking the square root of the variance.
Explanation:
To calculate the variance, follow these steps:
Find the mean of the data set.
For each data point, subtract the mean and square the result.
Find the average of the squared differences.
To calculate the standard deviation, take the square root of the variance.
For example, if the data set is {2, 4, 6, 8, 10}, the mean is 6. The squared differences are {(2-6)^2, (4-6)^2, (6-6)^2, (8-6)^2, (10-6)^2}, which equals {16, 4, 0, 4, 16}. The average of the squared differences is (16+4+0+4+16)/5 = 40/5 = 8. Therefore the variance is 8. The standard deviation is the square root of the variance, so in this case, the standard deviation is √8 = 2.83.

118 + ∠3 = 180 ( subtract 118 from both sides )
∠3 = 62°
A. 127 cm^2
B. 144.5 cm^2
C. 172 cm^2
D. 50 cm^2
Answer:
144.5cm^2
Step-by-step explanation:
First find area of the rectangle
Area of a rectangle = L*B
= 9*13 = 117cm^2
Now find area of the triangle
Area of triangle. = 1/2 base * height
Height = 13 - 8 =5cm
Area of the triangle = 1/2 *11 *5 = 27.4
Now area of the who figure is area of rectangle + area of triangle
= 117 + 27.5
= 144.5cm^2
For this case we have that the area of the figure is given by the area of a rectangle plus the area of a triangle.
The area of a rectangle is given by:
[tex]A = a * b[/tex]
Where a and b are the sides of the rectangle.
According to the figure we have:
[tex]a = 13 \ cm\\b = 9 \ cm[/tex]
So, the area of the rectangle is:
[tex]A = 13 * 9\\A = 117 \ cm ^ 2[/tex]
On the other hand, the area of a triangle is given by:
[tex]A = \frac {1} {2} b * h[/tex]
Where b is the base of the triangle and h the height. According to the figure we have:
[tex]b = 13-8 = 5 \ cm\\h = 11 \ cm[/tex]
Substituting:
[tex]A = \frac {1} {2} 5 * 11\\A = 27.5 \ cm ^ 2[/tex]
Adding up we have the total area is:
[tex]A_ {t} = 117 \ cm ^ 2 + 27.5 \ cm ^ 2\\A_ {t} = 144.5 \ cm ^ 2[/tex]

the average of five number is 25.if four of the numbers are 30,29,25 and 20,the average of the three larger numbers are
Answer:
28
Step-by-step explanation:
There are five numbers so the average must be x/5.
25= x/5
x= 125
30+29+25+20 = 104
Therefore the final number of the five must be 125-104=21
The 3 largest are still 30,29,25.
So their average is (30+29+25)/3
= 28
The average of the three larger numbers is 28
Let y be the 5th number.
Next, we shall determine the value of y. This can be obtained as follow:
Data: 30, 29, 25, 20 and yAverage = 25y =?Average = Sum of data / number of data
25 = (30 + 29 + 25 + 20 + y) / 5
25 = (104 + y) /5
Cross multiply
25 × 5 = 104 + y
125 = 104 + y
Collect like terms
y = 125 – 104
y = 21
Thus, the correct data are: 30, 29, 25, 20, 21
Finally, we shall determine the average of the three larger numbers.
Data: 30, 29, 25, 20, 21Three large numbers: 30, 29, 25Average =?Average = Sum of data / number of data
Average = (30 + 29 + 25) / 3
Average = 84 / 3
Average = 28
Therefore, the average the three larger numbers is 28
