Answer: kindly check explanation
Step-by-step explanation:
Given that number of dolphins = 800 with different length and ages
Median length = 5.8 feets
The median may be explained to be a measure of center which gives the information as regards around the middle or midpoint of a dataset. According to the information above, the median length if the 800 dolphins is 5.8 feets, this means the 50th percentile value is 5.8 feets and hence, Half of the dolphins sampled have a length which is greater than 5.8 feets and the other half has a length which is less than 5.8 feets.
(x^15)(x^-3) = x^(15 + (-3)) = x^12
n = 12
A. 3x-7y and -7+3x that is the correct answer
