Answer: A
2.94
Step-by-step explanation:
add all the numbers together -8+6.2+2.5+12+-2+-1.3+15+-2+0+7=29.4.
next you divide 29.4 by how much numbers there are in the equation which in this case its 10.
29.4/10=2.94
so its A :)
The mean absolute deviation of the given data set is 5.688 so option (D) will be correct.
What is the mean absolute deviation?The average distance between an observation's mean and its variance is shown by the mean absolute deviation, a measure of b. mean makes understanding simpler by using the data's original units.
Given the data set ;
-8,6.2,2.5,12,-2,-1.3,15,-2,0,7
Mean of this data set ;
Mean = (-8 + 6.2 + 2.5 + 12 - 2 - 1.3 + 15 - 2 + 0 + 7)/10
Mean = 29.4/10 = 2.94
Now,
Mean absolute deviation is given by ;
MAD = Σ |x - m|/n where x is the data value while n is a number of data and m is the mean.
So,
MAD = |-8 - 2.9 | + | 6.2 - 2.9| + |2.5 - 2.9| + .. so on / 10
MAD = 56.688/10
⇒ 5.688
Hence "The mean absolute deviation of the given data set is 5.688".

Do ya'll have any suggestions about this?
So I've been not doing my homework and stuff. I have been talking to online people, which I shouldn't have been. They found out and stuff. My parents are putting me in pubic school. They said I can finish the first semester but I'm not doing the second. I have finished 4 of my classes and finishing up the other two. I really don't want to go to pubic school.
My question is.
How do I focus on my homework and convince my parents to let me stay in online school?
My grades are at an A and rest are B's. I want to show them that I can stay in the second semester and do my homework. PLEASE HELP ME OUT
Hello, I know your situation. Ask them for another chance. Ask them to forgive you and you will do your homework. Say "If this continues, then I accept full consiquinses". Make sure you ACTUALLY stick to what you say. Now, to the focusing part... Try to do ATLEAST 2 lessons for each class. (depends what school you are attending) If it seems that you are finishing too fast (less than 2 hrs), then do more homework until your homework hours fits you.
Goodluck!
God Bless you!!!
i think the best thing you could do is just stay away from distractions and show them that you been doing fine with online classes...
or just tell them that a bunch of people at school are coughing or showing symptoms and that they might have c****
btw the second one might work but it risky so do both lol also virus-19 its a bad word lol

Alex wants to buy a case of drinks, he doesn’t have enough. The cost of the case is $30. He already has $2. He gets $8 every hour for work. How many hours does he need to work to get the amount he needs? Explain what your solution means in the context of the problem.
Answer:
Alex will need to work 4 hours.
Step-by-step explanation:
We know that Alex already has $2. This means that to get $30 he now only needs to get $28. If he gets $8 per hour, we know that 8 x 3 = 24, but that isn't enough. In this case, 3 is how many hours he works. Because $24 isn't enough, he needs to work 4 hours to get $32 in order to buy the case. Even though he has more money than he needs, he will be able to buy the case and save some extra money.
Answer:
3.5
Step-by-step explanation:
Wright, an equation first like this,
2+8x=30 because he needs 30 dollars but already has 2 and earns 8 dollars per hour.
Solve:
2 + 8x = 30
30-2= 28
28/8= 3.5 so he would need to work 3.5 hours.

When evaluating (8x+9)? -5 for x = 1, the given value of 1 is substituted for what part of the expression?
A.the exponent
B. The constant
C. the variable
D.any numerical value
Answer:
C. The variable
Step-by-step explanation:
The given value states that all values of x will be replaced by 1. The definition of a variable in algebra is a symbol for a number we don't know yet, so x will be the variable in this equation
Answer:
C. the variable
Step-by-step explanation:
(8x+9) -5 <----- The original question.
(8(1)+9) -5 <----- Replacing the variable.
(8 + 9) -5 <------ Completing the multiplication.
17 - 5 = <----- Doing the addition.
12
x = 1 tells us the "x" or the variable in this equation is a substitute for 1.

Answer:
1. 343
2. 64
3. 81
4. 12.25
Step-by-step explanation:
Answer:
[tex]7^{3}[/tex] = 343
4 cubed = 64
[tex]9^{2}[/tex] = 81
[tex](3.5)^{2}[/tex] = 12.25
Step-by-step explanation:
[tex]7^{3}[/tex] is the same thing as 7 * 7 * 7.
7 * 7 = 49
49 * 7 = 343
4 cubed can be written as [tex]4^{3}[/tex], which is the same as 4 * 4 * 4.
4 * 4 = 16
16 * 4 = 64
[tex]9^{2}[/tex] is the same as 9 * 9.
9 * 9 = 81
[tex](3.5)^{2}[/tex] is the same as 3.5 * 3.5.
3.5 * 3.5 = 12.25

Christel wants to know what the most popular color at her school is. She surveys students grades 1,2,3.
Will the sample be representative or biased? And can you please explain how that answer works. Thx! :)
Answer:
It will be biased.
Step-by-step explanation:
By surveying only grades 1, 2, and 3, she is not taking a representation of the entire school. It is possible that the popular color or the color the students like would change over time and the opinion of the younger kids could be different from that of the older kids. Therefore, the sample is biased unless she surveys students from all grades.
how many solutions dose 3x+2=2x+2+x have explain why below remember explain
Answer:
All real numbers are solutions.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x+2=2x+2+x
3x+2=(2x+x)+(2)(Combine Like Terms)
3x+2=3x+2
3x+2=3x+2
Step 2: Subtract 3x from both sides.
3x+2−3x=3x+2−3x
2=2
Step 3: Subtract 2 from both sides.
2−2=2−2
0=0
