Determine the mean absolute deviation of the data.9, 7, 11, 10, 8
Answer:
1.2
Step-by-step explanation:
First, we need to find the mean of the data. We do this by adding all of the given numbers than dividing it by the number of numbers given. For example, we will add 9+7+11+10+8 which is 45. Since there are 5 given numbers, we are going to divide 45 by 5 which is 9. Now, we need to find the difference (subtraction) of all of the numbers in relation to 9. For example, for 9, we do 9-7 which is 2. Keep 2 in mind. Then we do 11-9 which is also 2. 10-9 is 1. 9-9 is 0. And finally, 9 minus 8 is also 1. Then, like what we did before, we need to find the mean of all of these differences. 2 plus 2 plus 1 plus 0 plus 1 is 6. Then, we divide 6 (our total of these differences) by 5 (the number of differences) 6 divided by 5 is 1.2 so there is your MAD and answer.
The mean absolute deviation of the given data is 1.2.
What is mean absolute deviation?The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.
Here's how to calculate the mean absolute deviation.
Data given: 9, 7, 11, 10, 8
Step 1: Calculate the mean.
[tex]mean = \frac{sum\ of\ observations}{number\ of\ observations} \\\\mean = \frac{9 + 7+11 + 10 + 8}{5}\\ \\mean =9[/tex]
Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.
Data Distance from mean
9 |9 - 9| = 0
7 |7 - 9| = 2
11 |11 - 9| = 2
10 |10 - 9| = 1
8 |8 - 9| =1
Step 3: Add those deviations together.
Sum of deviations = 0 + 2 + 2 + 1 + 1 = 6
Step 4: Divide the sum by the number of data points.
Mean absolute deviation = [tex]\frac{sum\ of\ deviations}{number\ of\ observations}\\ \\[/tex] = [tex]\frac{6}{5} = 1.2[/tex]

A large emerald with a mass of 982.7 grams was recently discovered in a mine. If the density of the emerald is 2.76 grams over centimeters cubed, what is the volume? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.
Answer:
356.05 cm³
Step-by-step explanation:
We are looking for the volume. The formula is density = mass / volume.
If we plug in our numbers, our formula would be 2.76 = 982.7 / V.
Multiply both sides by V and your formula would be (V) 2.76 = 982.7.
Divide both sides by 2.76 and you would get V = 356.05.
The volume of the given large emerald is required.
The volume of the given large emerald that was discovered in the mine was 356.05 cm³. The calculations to find this value is shown below.
Densitym = Mass of object = 982.7 grams
[tex]\rho[/tex] = Density of the material the object is made of = 2.76 grams over centimeters cubed
The relation between mass, volume and density is given by
[tex]V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{982.7}{2.76}\\\Rightarrow V=356.05072\approx 356.05\ \text{cm}^3[/tex]

A 1 3/11
B 1 8/11
C 4 4/11
D 5 9/11
Answer:
the amount of pages typed after 1/3 of an hour is given. Multiply this number by 3 to get the full hour of pages types.
1 5/12 * 3 = 3(1) + 3(5/12)
= 3 5/4

55% of 6th grade students voted in the student election. 440 sixth grade students voted in the student election. How many total 6th graders are in the school
Answer:
800. Here's why:
Step-by-step explanation:
This indicats that 440 students make up 55% of the 6th grade population. We can write this as
55/440.
We also know that 'x' total students make up 100% of the 6th-grade population, so we can write this as
100/x.
55/440 must be equal to 100/x. When cross multiplied, it becomes 50x=44000. If we divided each side by 50, we'll find that x=880. Therefore, there are 800 6th graders
Answer:495
Step-by-step explanation:
440 rounds up to 450,450+450=900-the 10 we rounded so 890-440 is 450 which is half so we need to add 440 to 550 to get 990 and we half 990 to get 495 and that is your answer i think im very sorry if this is wrong btw a sixth grader did this please find out a way to reply to my comment or something like that to tell me if i am right.

The value of k lies between 2.2 and 2.3.
Select all possible values of k.
Answer:
Its easy... 5 and 5.04!
Step-by-step explanation:
You have to look at it properly. It says "The value of SQUARE ROOTED K."
So all you have to do is square root them and whatever is in between 2.2 and 2.3 is ur answer. Ur answer 5 and 5.04.
The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that √k falls between 2.2 and 2.3
For k = 1.49, √1.49 = 1.22 which is not between 2.2 and 2.3
For k = 4.8, √4.8 = 2.19 which is not between 2.2 and 2.3
For k = 5, √5 = 2.2 3which is between 2.2 and 2.3
For k = 5.04, √5,04 = 2.23 which is between 2.2 and 2.3
For k = 5.3, √5.3 = 2.302 which is not between 2.2 and 2.3
For k = 6, √6 which is not between 2.2 and 2.3
The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.
