Answer:
The median is 61.
Step-by-step explanation:
To find the median, you take the number that is numerically in the center of the data set. Since this set has two numbers like that (60 and 62), you find the mean of those two numbers. This leaves us with 61.
median is 61.
= 7.4z + 8z - 12
= (7.4 + 8)z - 12
= 15.4z - 12
69
term = 159 - 3n
no idea too hard but try math way
