Part A: What is the mean of the data? Show your work. (4 points)
Part B: Use your answer from Part A to calculate the mean absolute deviation for the data. Show your work. (6 points)
Answer:
Part A: The mean of the data is 8.
Part B: The Mean Absolute Deviation is 0
Step-by-step explanation:
Part A: For the mean, you add all the numbers up and then divide your answer by how many numbers you have. So You would do 64 divided by 8 and it gives you 8.
B: Since the Mean is 8, You would subtract each number by 8, but add. (I'm Going To show it under here)
|8 - 8| + |9 - 8| + |9 - 8| + |7 - 8| + |8 - 8| + |6 - 8 | + |9 - 8| + |8-8| .
0 1 1 -1 0 -2 1 0
Add them up and it should give you 0.

Answer:
A. both coordinates are positive.
Step-by-step explanation:
I'm attaching a picture. The lower right quadrant/quarter is where x is positive and y is negative. When you "reflect over the y axis" it's mirroring the position by flipping it above the y axis.
In my picture, I used the example of a filled in dot in the lower right quadrant at +2 x, and -2 y. Right above that, in the upper right quadrant, there's an unfilled circle at +2 x, and +2 y. The second point is the first after being "reflected over the y axis." X stays the same, but the y goes from negative to positive.
I hope this helps. Please ask me if it's still confusing.
please help I'm terrible at this stuff
Mary has $600 in her savings account. She withdrew $120 from an ATM and she used her debit card to buy a present for her mom that cost $50. Which integer represents the change to Mary’s account balance that is shown on her statement when she made the withdrawal from the ATM?
a) $ 430
b) - $ 170
c) - $50
d) - $120
Answer: D
Step-by-step explanation:
Just showing what she did to the account at the ATM withdrawal, she took out $120. It wouldn't show the 50 from using her debit at the time of using the ATM, and she's removing money from the account so it'd be D.
Cole is building a model rocket in science class. He selects the rocket parts from a set of solid cylinders and cones made from metal. Cole wants to build a rocket with the dimensions shown. For safety purposes, the maximum lift-off weight of each rocket is 10 pounds. Will Cole’s rocket meet the requirement for launch?
Part A
What will be the total length of the assembled rocket? Explain how you found your answer.
Part B
What is the approximate volume of the rocket. Use 3.14 for π. Explain.
Part C
If Cole’s rocket parts are made of aluminum weighing 0.006 pound per cubic centimeter, will Cole be able to launch his rocket? Explain.
A.
30 since 25 + 5 = 30
The maximum lift-off weight of each rocket is 10 pounds thus, Cole’s rocket doesn't meet the requirement for launch.
What is the volume of a cylinder?The volume of the cylinder is the product of the height, pie, and square of the radius.
The volume of the cylinder = [tex]\pi r^{2} h[/tex]
Part A
The total length of the assembled rocket will be the length of the cone and the cylinder.
Height of the cone
[tex]\sqrt{l^{2} -r^{2} } \\\\\sqrt{5^{2} -4^{2} } \\[/tex] = 3 cm
The total length of the assembled rocket = 25 + 3 = 28cm
Part B
The volume of the rocket is the combined volume of the cone and cylinder.
= [tex]\pi r^{2} h[/tex] + 1/3[tex]\pi r^{2} h[/tex]
= 4/3 [tex]\pi r^{2} h[/tex]
= 4/3 × 3.14 × 16 × 28
= 1875.62 cubic cm
To convert cm into pound
1875.62 cubic cm = 4.135 pound
Part C
If Cole’s rocket parts are made of aluminum weighing 0.006 pounds per cubic centimeter.
Then 1875.62 cubic cm × 0.006
= 11.253
For safety purposes, the maximum lift-off weight of each rocket is 10 pounds. but Cole’s rocket doesn't meet the requirement for launch.

Can you help me please.
Answer:
255
Step-by-step explanation:
Take your rectangle first
22*10 = 220 cm^2
Now your triangle:
The base is 7cm ( 17 - 10), and the height is 10 cm (22-12)
A=10 * (7/2)
A= 35
Now add both together.
Answer: 255 cm squared
Step-by-step explanation:
the area of the rectangle is length x width. 22 x 10 = 220.
the sides of the triangle are found by subtracting the sides of the rectangle.
22 - 12 = 10 and 17 - 10 = 7.
the area of the triangle is base x height / 2. so 10 x 7 / 2 = 35.
add the area of the rectangle and the area of the triangle.
220 + 35 = 255.

what is 7 (x-2) simplified
Answer:
7x-14
Step-by-step explanation:
you must use the distributive property. to do this, you must multiply the value outside the parentheses (7) by the first term in the parentheses (x) and add that to the multiplication of 7 and the second term (-2). 7 multiplied by x is 7x, and 7 multiplied by -2 is -14. when you add these two values, you get 7x-14.
Answer: 7x−14

Ten rabbits are put in an enclosed wildlife ranch and the rabbit population triples each year, as shown in the table.
Year Rabbit Population
0 10
1 30
2 90
3 270
4 810
5 2,430
Complete each of the 2 activities for this Task.
Activity 1 of 2
Write an equation where y represents the number of rabbits in x years.
Activity 2 of 2
A second population of 10 rabbits is placed in a second enclosed wildlife ranch and doubles each year.
Select all statements that are TRUE when comparing the equation of the second group of rabbits to the first group.
A.
The base of the exponent will change from 3 to 2.
B.
The function will become quadratic.
C.
The y-intercept will change.
D.
The second population will increase less rapidly.
Answer:
C
Step-by-step explanation:
First, we have to find the equation that will give the rabbit population as a function of time and the initial population.
The equation we need turns out to be Population = a0 x 3y where a0 is the initial population and y is the number of years,
To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.
You can now find the difference in the number of rabbits at year 3 for the different starting populations.

What sequence of transformations, when applied to △ABC , shows that △ABC is similar to △ A ′ B ′ C ′ ? dilation with respect to the origin by a scale factor of 2 followed by a translation of 2 units left dilation with respect to the origin by a scale factor of 1 2 followed by a translation of 2 units right translation of 2 units right followed by a dilation with respect to the origin by a scale factor of 1 2 translation of 2 units left followed by a dilation with respect to the origin by a scale factor of 1 2
Answer:
The correct sequence of transformations that shows that △ABC is similar to △A′B′C′ is:
translation of 2 units left followed by a dilation with respect to the origin by a scale factor of 12.
Step-by-step explanation:
A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object.
In this case, we can see that a dilation with respect to the origin by a scale factor of 12 would stretch or shrink the triangle, but would not change the angles.
Therefore, we need to apply a translation first to move the triangle into the correct position.
So, we first translate the triangle 2 units left, which does not change its shape or size, but moves it to a position where it can be more easily compared to the other triangle.
Then, we apply a dilation with respect to the origin by a scale factor of 12, which stretches or shrinks the triangle but does not change its shape.

Answer:
18x + 6 = 2( 9x + 3 )
18x + 6 = 3( 6x + 2 )
18x + 6 = 6( 3x + 1 )
Step-by-step explanation:
Answer:
1. 2(9x+3)
2. 3(6x+2)
3. 6(3x+1)
Step-by-step explanation:
Okay so in the first one there is a 2 outside of the parentheses which means we will multiply whatever is inside of the parentheses by 2.
9x*2=18x
3*2=6
18x+6=2(9x+6)
Okay so in the second one there is a 3 outside of the parentheses which means we will multiply whatever is onside of the parentheses by 3.
6x*3=18x
2*3=6
18x+6=3(6x+2)
Okay so in the third one there is a 6 outside of the parentheses which means we will multiply whatever is inside of the parentheses by 6.
3x*6=18x
1*6=6
18x+6=6(3x=1)
