Let the numbers be x = 5x+18
3(5x+18) + 4x= 16
15x+ 54+ 4x= 16
19x = 16-54
X=-38/19
X= -2
5x+18= 5 × -2+18 = 8
Answer:
80 cookies
Step-by-step explanation:
25% of 64 is 16

Best measure of center
The mean is considered the best measure of center when there are no outliers in the given data.
Outlier is when a particular data set is far away from other datasets.
For instance: 20 is an outlier in the following data sets:
Also, the given data are not open-ended.
An open-ended data is as follows:
Since we do not have any of the above conditions, then the mean is the best center to use.
-2x^4 + 10x^3 - 21x^2 + 19x - 4
that should be the right answer
