Because this person is isolating for x, they would add 3 to each side, to have x by itself.
This will leave them with the equation 3x=18
So 3x=18 is most likely the next step
If you start adding all the way until you find what equals 9, then you multipliy the answer to see if it gets the answer 18.
8+1=9, so you check to see if 8 times 1 equals 18, this doesn't
5+4=9, check 5 times 4 equals 20, this doesn't equal 18
6+3=9, check 6 times 3 equals 18, so 6+3 is your answer!
Hope I helped!
Answer:
The sample 2 has a lowest value of SE corresponding to the least sample variability.
Step-by-step explanation:
As the value of the sample means and standard deviations are not given, as similar question is found online from which the values of data is follows
The data is as attached with the solution. From this data
Sample 1 has a mean of 34 and a SE of 5
Sample 2 has a mean of 30 and a SE of 2
Sample 3 has a mean of 26 and a SE of 3
Sample 4 has a mean of 38 and a SE of 5
As per the measure of the sample variability is linked with the value of SE or standard error. Which is lowest in the case of sample 2 .
So the sample 2 has a lowest value of SE corresponding to the least sample variability.
Answer is 9/4 (last choice)
cause
slope = (-6-3)/(-2-2) = -9/-4 = 9/4
