Answer:
Sampling Error
Step-by-step explanation:
When the researcher randomly selected 200 people, he is creating an sample or subset from the population, that would be all the people in the earth. The error obtained was product of the fact that the analysis he made was estimated from the sample and not the whole population. There is no other mentioned factor that could cause an error, so the answer would be a sampling Error.
The Absolute Value: 2|x| ---> 3
Look for the Absolute Value in the equality that we have found (entered) 2|x| ---> 3
-----------------------------------------------------------------
Your first term: 2|x|
If you had a negative term: -2×(x)
But, if youre working with the positive term then it would be: +2×(x)
-----------------------------------------------------------------
Now, 2 × x ----> 3
The value of 'x' becomes a negative
So, -x = 3 over the number 2 ( 3 / 2 <--- this is what I am talking about if in case you don't get what I am saying )
Since you don't have anything else ... lets make a -1 from each other of your sides
the fraction becomes negative as well
x = 3 / 2
----------------------------------------------------------------
2[x] ----> 3
2 [x] ---> 3
If we divide by the number 2 we get the value of x as -----> 3 / 2
-----------------------------------------------------------------
For the first one: 3 / 2
For the second one: -3 / 2
Therefore we finally get to your result, which is: ✅A: [-3 / 2 , 3 / 2} ✅
Answer:
m=3
Step-by-step explanation:
(7m*3-1)/3=2
21m-1=2*3
21m=6+1
21m=7
21/7=m
3=m
