The mean absolute deviation for people without high school diploma is?
Answers
Answer:
Hope it helps
Step-by-step explanation:
The mean absolute deviation for a high school diploma is more than the mean absolute deviation for no high school diploma.
What is the mean absolute deviation?It is the average distance between each data point and the mean.
The mean absolute deviation is given as
[tex]\rm MAD = \dfrac{\Sigma _{i = 1}^n|x_i - \mu|}{n}[/tex]
The table is given below.
No high school diploma High school diploma
10 19
9.50 15.25
11.50 14
13 15.75
The mean of No high school diploma will be given as,
μ₁ = (10 + 9.50 + 11.50 + 13) / 4
μ₁ = 11
Then the mean absolute deviation is calculated as,
(MAD)₁ = (|10 - 11| + |9.5 - 11| + |11.5 - 11| + |13 - 11|) / 4
(MAD)₁ = 1.25
The mean of high school diploma will be given as,
μ₂ = (19 + 15.25 + 14 + 15.75) / 4
μ₂ = 16
Then the mean absolute deviation is calculated as,
(MAD)₂ = (|19 - 16| + |15.25 - 16| + |14 - 16| + |15.75 - 16|) / 4
(MAD)₂ = 1.50
The mean absolute deviation for a high school diploma is more than the mean absolute deviation for no high school diploma.

Step-by-step explanation:
You didn't provide any dimensions to test the answers with, but here is how you could solve the problem.
A rectangular prism is just an oblong cardboard box basically. Think about how you would unfold that box. It would be made up of 3 pairs of rectangles (2 end pieces, the top and bottom, and 2 sides). To calculate its surface area you just calculate the areas of each piece and add them up.
The overall formula ends up being:
Area = 2(LW) + 2(LH) + 2(WH)

A reporter determines a baseball player’s batting average, which is a ratio of the number of hits to number of times at bat. The result is shown on a calculator as 0.212121....Write this repeating decimal as a fraction.
Answers
Answer:
21/99 or 7/33
Step-by-step explanation:
x = 0.212121
Then we multiple the decimal and x by hundred.
100x = 21.212121
Then we subtract the 21.212121 by 0.212121.
100x = 21.212121 - 0.212121
But when you are subtracting 100x, you need to subtract 100x by x because in the first step it said x = 0.212121.
100x - x = 21.212121 - 0.212121
You will have at the end is
99x = 21
Divide 99 on both side and you left with
21/99 or 7/33 simplified version
Find the perimeter of the quadrilateral.

inches.
Answers
Answer:
129 inches
Step-by-step explanation:
If x=2, just substitute in the x values for each side. Your lengths are 31, 32, 22, and 44.
4(2)^2+8(2)= 16+16=32
3(2)^2-5(2)+20=12-10+20=22
7(2)+30= 14+30=44
You are given an additional side of 31.
Add the values up together.
31+32+22+44=129
Daniel has read 60% of a book. He has 28 more pages to finish. How many pages are there in the book? There are nothing pages in the book.
Answers
The total number of pages in Daniel's book is 70 pages.
Given that Daniel has read 60% of it and that he has 28 pages left to finish it. The remaining 28 pages represent the
40% of the book that Daniel has not read yet.
We can set up the equation where 40% of the total page number (represented as x) equals 28 pages.
0.40x = 28
x = 28 / 0.40
x = 70
There are 70 pages in the book.
To find the total number of pages in the book, we'll start by setting up an equation based on the information provided. Let's denote the total number of pages in the book as x.
Daniel has read 60% of the book, leaving 40% unread. Given that he has 28 more pages to finish, we can express this information in an equation:
0.40x = 28
This equation represents the 40% of the book that Daniel has yet to read, which equals the 28 pages remaining.
To find the total number of pages ( x ), we divide both sides of the equation by 0.40:
[tex]\[ x = \frac{28}{0.40} \][/tex]
x = 70
So, there are 70 pages in the book. This solution implies that there are 70 pages, considering that "nothing" is simply a placeholder value and doesn't affect the calculation.

Factor 4x^2 + 49y^2 please.
Answers
Answer:
(2x + 7yj)(2x - 7yj)
Step-by-step explanation:
Both 4x^2 and 49y^2 are perfect squares, and
4x^2 + 49y^2 is the sum of two squares.
There is a formula for factoring the difference of two squares:
a^2 - b^2 = (a - b)(a + b) (all real numbers here), but unless imaginary numbers are allowed, there's no formula for factoring the sum of two squares.
If imaginary numbers are allowed, then a^2 + b^2 factors into
(a + jb)(a - jb).
Following this pattern, 4x^2 + 49y^2 factors into (2x + 7yj)(2x - 7yj)
a^2 + b^2 = (a + b)(a
Without drawing the graphs, find the points of intersection of the lines:
11x–6y=2 and –8x+5y=3
PLZZZZZZZ HELP!
Answers
The point of intersection of the lines given by the equations [tex]\( 11x - 6y = 2 \) and \( -8x + 5y = 3 \) is \( (4, 7) \).[/tex]
To find the points of intersection of the given lines, we need to solve the system of linear equations simultaneously.
The given equations are:
[tex]\[ 11x - 6y = 2 \quad \text{(Equation 1)} \][/tex]
[tex]\[ -8x + 5y = 3 \quad \text{(Equation 2)} \][/tex]
We can solve this system using the method of substitution or elimination. Let's use the elimination method to find the values of [tex]\( x \)[/tex]and [tex]\( y \).[/tex]
First, we will make the coefficients of [tex]\( y \)[/tex] the same in both equations by multiplying Equation 1 by 5 and Equation 2 by 6:
[tex]\[ 5(11x - 6y) = 5(2) \][/tex]
[tex]\[ 6(-8x + 5y) = 6(3) \][/tex]
This gives us:
[tex]\[ 55x - 30y = 10 \quad \text{(Equation 3)} \][/tex]
[tex]\[ -48x + 30y = 18 \quad \text{(Equation 4)} \][/tex]
Now, we add Equation 3 and Equation 4 to eliminate [tex]\( y \):[/tex]
[tex]\[ (55x - 30y) + (-48x + 30y) = 10 + 18 \][/tex]
[tex]\[ 7x = 28 \][/tex]
Dividing both sides by 7, we get:
[tex]\[ x = 4 \][/tex]
Now that we have the value of [tex]\( x \)[/tex], we can substitute it back into either Equation 1 or Equation 2 to find the value of [tex]\( y \)[/tex]. Let's use Equation 1:
[tex]\[ 11(4) - 6y = 2 \][/tex]
[tex]\[ 44 - 6y = 2 \][/tex]
Subtracting 44 from both sides, we get:
[tex]\[ -6y = -42 \][/tex] Dividing both sides by -6, we get:
[tex]\[ y = 7 \][/tex].

Select the statement that correctly completes the sentence. When using more than one adjective, ________.
A. size comes after color
B. size comes after shape
C.size comes before color
D. size comes before opinion
Answers
Answer:
more comfortable
Step-by-step explanation:
Final answer:
When using more than one adjective, 'size comes before color', which is option C. Adjectives in English typically follow an established order, with the size adjective placed before the color adjective.
Explanation:
The correct statement that completes the sentence when using more than one adjective is C. size comes before color. In English, adjectives follow a specific order in which they appear before a noun. This order is generally: opinion, size, shape, age, color, origin, material, and purpose. Therefore, size should be placed before color when describing a noun with multiple adjectives.
For example, when arranging adjectives in a sentence, the phrase would be 'a small green book' rather than 'a green small book'. The adjective 'small' represents the size and 'green' represents the color, and according to the correct adjective order, size should come before color.

-2, 1 1⁄2, -2 3⁄4, 3⁄10
Answers
Answer:
11/2, 3/10 , -2, -2 3/4
Step-by-step explanation:
negatives are definitely on the least side. And 11/2 is 5 1/2 which is way greater 3/10. -2 3/4 means it is 3/4 more away from 0 than -2 is. So here!
The order from greatest to least is:
1 1/2 3/10 -2 -2 3/4-2: This is a negative number, which means it is less than zero.
1 1/2 (or 1.5): A positive number greater than zero.
-2 3/4 (or -2.75): This is also a negative number and is less than -2.
3/10 (or 0.3): This is another positive number, but less than 1.
Negative numbers always rank lower than positive numbers.
Among the negative numbers, -2 is greater than -2.75.
Comparing the positive numbers:
1.5 is greater than 0.3.

Sam is baking cakes at her parent’s bakery. She gets paid 20 a week in addition to 5 for every cake she bakes. She made 50 this week. Write an equation to show how many cakes Sam baked this week
Answers
Answer:
i think it is 20 + 5x = 50 or f(x)=2(3^x)
Step-by-step explanation:
equation to show how many cakes sam baked this week:
20 + 5x = 50
20 = 20 dollars
5 = 5 more dollars
x = number of cakes
therefore, sam earned $50 this week.
Answer:
20+5x=50
x will represent the number of cakes she baked
she gets paid $5 for every cake she bakes, this is where the 5x comes from
she makes $20 ("in addition" that's where the "+20" comes from) a week. However, in this case we're only talking about what she made in one week, hense why there is no variable attached to the 20
she makes a total of $50
20+5=50
she baked a total of 6 cakes. How?
subtract 20 from both sides so you have:
5x=30
divide both sides by 5 to get x by itself:
x=6

Answer:
85°
Step-by-step explanation:
Since it is a trapezoid one pair of opposite sides will be parallel.
