-1/3(x - 15) = -4
step 1 : multiply both sides by -3, step 2 : add 15 to both sides
because when u multiply both sides by -3, this cancels out the -1/3 on the left side leaving u with : x - 15 = -4 * -3.....x - 15 = 12.....and then u would add 15 to both sides....giving u : x = 12 + 15.....x = 27
Answer:
b
Step-by-step explanation:
I believe that the answer is AA similarity (A).
Both mean and median are measures of the center of a set of data.
Mean is normally preffered to the median except if there is an outlier that has a tendency to affect the mean.
An outlier is a data point that significantly differs from the other data points in a sample.
In the data set above, there is no outlier that will affect the mean.
Therefore, he should use the mean because there are no outliers that affect the mean.
The answer is 52 hopefully this help
