Find the Mean Absolute Deviation:
{1, 10, 7, 6, 4,8}
A) 1.7
B) 1.9
C) 2.1
D) 2.3
E) 2.5
Answer:
2.33
Explanation:
First find the mean:
1 + 10 + 7 + 6 + 4 + 8 = 36
36 / 6 ( there are 6 total numbers) = the mean is 6
Then subtract the mean from each number:
1 - 6 = -5
10 - 6 = 4
7 - 6 = 1
6 - 6 = 0
4 - 6 = -2
8 - 6 = 2
(don't worry about the negatives)
5 + 4 + 1 + 0 + 2 + 2 = 14
14 / 6 ( again, there are 6 total numbers) = 2.33

Answer:
y = -2x + 2
Step-by-step explanation:
y = mx + b
b is the y-intercept and is 2.
m is the slope.
Start at (0, 2), the y-intercept. Go down 2 units and right 1 unit.
That is a rise of -2 and a run of 1.
m = slope = rise/run = -2/1 = -2
Answer: y = -2x + 2

Two times the smaller of two consecutive even integers is 18 more than the larger.
Answer:
2x = x+1 + 18
---
x = 19
-----------
x+1 = 20
Step-by-step explanation:
The smaller of the two consecutive even integers is 20, and the larger is 22.
What is a number system?A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols.
Let's call the smaller of the two consecutive even integers "x".
Since the integers are consecutive and even, we know that the larger integer must be 2 more than the smaller integer. Therefore, we can represent the larger integer as "x + 2".
According to the problem statement, two times the smaller integer (2x) is 18 more than the larger integer (x + 2). We can express this algebraically as:
2x = x + 2 + 18
Simplifying this equation, we can combine like terms on the right-hand side:
2x = x + 20
Subtracting x from both sides, we get:
x = 20
Therefore, the smaller of the two consecutive even integers is 20, and the larger is 22 (since 20 + 2 = 22).

Answer: 16.75 milliliters
Step-by-step explanation:
I believe it is 16.75 because 0.35 + 16.4 is 16.75 why is it addition decimals? Because it says How many milliliters does the mixture contain. It is talking about both combined, I hope this helps you if not sorry this was rushed! I am also 3rd Grade this Year! :D

$175 at 5.45% for 36 months
What is the difference between the interest amount in the account if you did simple and compound interest?
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
$175 at 5.45% for 36 months
First, we need to determine the monthly interest:
Monthly interest= 0.0545/12= 0.004542
Now, we will calculate the interest earned using both simple and compound interest:
Simple interest:
I= P*r*t
I= 175*0.004542*36
I= $28.61
Compound interest:
I= PV*(1+i)^n - PV
I= 175*(1.004542^36) - 175
I= $31.01

What is Pythagoras's theorem?In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

p = [tex]\sqrt{179^2 + 203^2[/tex].
p = [tex]\sqrt{32041 + 41209[/tex].
p = [tex]\sqrt{73250[/tex].
p = 270.

Saul makes Apple Green paint and Citron Green paint.
He mixes green paint with white paint as shown.
Apple Green
green : white = 2:1
Citron Green
green : white = 4:5
He makes 90 litres of Apple Green paint.
To this Apple Green paint he adds 24 litres of green paint.
How much more white paint does he need to add to make Citron Green paint?
Your final line must say, He needs to add ... litres of white paint.
Answer:
You would need 18 litres more of white paint to create Citron Green paint.
Step-by-step explanation:
Given the Green Apple paint contains 24 litres of green paint in a 2:1 ratio with white paint, we can conclude the mixture contains 12 litres of white paint because 24 / 2 = 12.
In a Citron Green paint mixture, the current paint mixture would contain 24 litres of green paint in a 4:5 ratio with white paint. This would mean there are 30 litres of white paint in this mixture.
24 / 4 = 6
5 x 6 = 30
To make Citron Green paint, you would need 18 litres more of white paint.
30 - 12 = 18
The amount of white paint that needs to be added is required.
He needs to add 75 liters of white paint.
RatiosLet x be amount of green paint
y be amount of white paint.
Amount of apple green paint is 90 L, so
[tex]x+y=90[/tex]
The ratio of green to white paint is 2:1, so
[tex]\dfrac{x}{y}=\dfrac{2}{1}[/tex]
Rearranging the equation
[tex]x=2y[/tex]
Substituting in the first equation
[tex]2y+y=90\\\Rightarrow y=\dfrac{90}{3}\\\Rightarrow y=30\ \text{L}[/tex]
Amount of white paint is 30 L.
Amount of green paint is [tex]x=2y=2\times 30=60\ \text{L}[/tex]
Amount of green paint added to the apple green paint is 24 L.
Amount of green paint in the mixture is 60+24 = 84 L.
Let the amount of white paint to be added in the mixture be y.
This will be added to the 30 L of white paint in the original mixture.
The ratio of green:white = 4:5, so
[tex]\dfrac{84}{y+30}=\dfrac{4}{5}\\\Rightarrow \dfrac{84\times 5}{4}=y+30\\\Rightarrow 105=y+30\\\Rightarrow y=105-30=75[/tex]
The amount of white paint to be added is 75 L.

A line that includes the point (6,-4) has a slope of -1/2 what’s the equation in slope intercept form
Answer:
The equation in the slope-intercept form will be:
[tex]\:y=-\frac{x}{2}-1[/tex]Step-by-step explanation:
Given
Point (6, -4)Slope m = -1/2Important Tip:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
[tex]m[/tex] represents the slope[tex]b[/tex] is the y-interceptIn our case,
(x, y) = (6, -4)m = -1/2Step 1 of 2
Determine the y-intercept b
substitute m = -1/2 and (x, y) = (6, -4) in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]-4\:=-\:\frac{1}{2}\left(6\right)+b[/tex]
switch sides
[tex]-\frac{1}{2}\left(6\right)+b=-4[/tex]
[tex]-3+b=-4[/tex]
Add 3 to both sides
[tex]-3+b+3=-4+3[/tex]
simplify
[tex]b=-1[/tex]
Thus, the y-intercept b = -1
Step 2 of 2
substitute the values
substitute b = -1 and m = 1/2 in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]y=-\frac{1}{2}x+\left(-1\right)[/tex]
[tex]\:y=-\frac{x}{2}-1[/tex]
Conclusion:
Therefore, the equation in the slope-intercept form will be:
[tex]\:y=-\frac{x}{2}-1[/tex]

Michelle is four times as old as Fiona. Fiona is twice as old as Madeline. Madeline is seven years old. How old is Michelle?
Answer:
michelle is 56 years old
Step-by-step explanation:
start with madeline you know she's 7, move on to fiona we know she is twice as old as madeline so we mulitply 7 times 2, we get 14. now we know fiona is 14 and in order to find michelles age we multiply times 4 because shes four time fionas age. 14x4=56.
First find fionas age
Fiona is 2x as old as madeline
madeline is 7
mulitply 7*2 which gives you 14
that means fiona is 14
multiply 14 by 4 which gives you 56
