The number of toys owned by eight classmates is shown below:
4, 3, 4, 5, 6, 6, 8, 4
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: 5
Part B: 2
Step-by-step explanation:
to find the mean all you have to do is add all the numbers together and then divide it by how many numbers there are in the data set
3+4+4+4+5+6+6+8=40
40÷8=5
so the mean is 5
next to find the mean of absolute deviations you need to subtract each number in the data set from the mean then divide it by how many numbers are in the data set (if you get a negative like 6-5=-1 just take away the negative sign to make it positive)
5-3=2
5-4=1
5-4=1
5-4=1
5-5=0
6-5=-1
6-5=-1
8-5=-3
2+1+1+1+0+1+1+3=10
10÷5=2
so the mean absolute deviation is 2

Answer:
y = 2 that sign means equal to so its literally another way to write =
so to graph this inequality you graph 2 on the y axis thats it
Step-by-step explanation:
13. The manager of a landscaping company collected data for an entire summer. Before each job he completely filled the gasoline tank for his mower. After each job, he recorded the square footage of the lawn that was mowed as well as how much gasoline remained in the tank. As expected, larger lawns left him with very little gasoline in the tank. At the end of the season he displayed the data in a scatterplot and saw that the relationship between lawn size and gas remaining was roughly linear. The value of r? was 0.85.Find and interpret the value of the correlation between the lawn size and the amount of gasoline remaining in the tank at the end of the job.

Answer:
0.75
Step-by-step explanation:
Imagine four quarters, 1 quarter equals 25 cents. So adding 2 more quarters, 3 total, would equal 75 cents. 25 + 25 + 25 = 75. Your answer is 0.75! Hope this helps!

Answer:
We add up all the numbers:
84 + 72 + 96 + 97 + 75 + 83 + 81 = 588
Since there are 7 numbers we divide by 7
588 divided by 7 = 84 is your mean
Step-by-step explanation:
How to find mean:
Add up the numbers, divide by the many numbers there are and thats how you find your mean.

Quadrilateral CDEF is inscribed in circle A. Which statements complete the proof to show that ∠CFE and ∠CDE are supplementary?
Quadrilateral CDEF is inscribed in circle A, so mARC CDE + mARC CFE= 360°. ∠CFE and ∠CDE are inscribed angles, which means that their measures are _________________. So, _________________. Using the substitution property of equality, 2 ⋅ m∠CFE + 2 ⋅ m∠CDE = 360°. Using the division property of equality, divide both sides of the equation by 2, resulting in m∠CFE + m∠CDE = 180°. Therefore, ∠CFE and ∠CDE are supplementary.
Answer:
The statements that complete the proofs are;
First statement
One half the measure of their intercepted arcs
Second statement
mARC CDE = 2·m∠CFE and mARC CFE = 2·m∠CDE
Step-by-step explanation:
The two column proof that ∠CFE and ∠CDE are supplementary is presented as follows;
Statement [tex]{}[/tex] Reason
Quadrilateral CDEF is inscribed is circle A [tex]{}[/tex] Given
[tex]m\widehat{CDE}[/tex] + [tex]m\widehat{CFE}[/tex] = 360° [tex]{}[/tex] Measure of angle round a circle
∠CFE and ∠CDE are inscribed angles [tex]{}[/tex] Given
∠CFE + ∠CDE = 1/2 × ([tex]m\widehat{CDE}[/tex] + [tex]m\widehat{CFE}[/tex]) [tex]{}[/tex] Inscribed angles are (i) one half the measure of their intercepted arcs
2 × (∠CFE + ∠CDE) = ([tex]m\widehat{CDE}[/tex] + [tex]m\widehat{CFE}[/tex])
So, (ii) [tex]m\widehat{CDE}[/tex] = 2 × m∠CFE and [tex]m\widehat{CFE}[/tex] = 2 × m∠CDE From the inscribed angle theorem above (See attached drawing)
2·m∠CFE + 2·m∠CDE = 360° [tex]{}[/tex] Using substitution property of equality
(2·m∠CFE + 2·m∠CDE)/2 = 360°/2 → m∠CFE + m∠CDE) = 180° [tex]{}[/tex] Dividing both sides by 2
m∠CFE and m∠CDE) are supplementary [tex]{}[/tex] Angles that sum up to 180°
The statements that complete the proofs are;
(i) One half the measure of their intercepted arcs
(ii) mARC CDE = 2·m∠CFE and mARC CFE = 2·m∠CDE
Answer:
1/2 the measure of their intercepted arcs; m arc CDE= 2 ⋅ m∠CFE and arc CFE= 2 ⋅ m∠CDE (or C).
