Answer 7

Ok can you at least find the answer to the questions below:
Find the sum of the elements: 5.2+8.3+8.5+7.7+7.8+y = ?
What is the number of elements above = ?

Answer 8

Sum of elements = 37.5+y
# of elements = 6 (5.2, 8.3, 8.5, 7.7, 7.8 and y)
Equation:
\[7.1 = \frac{ 37.5+y }{ 6 }\]
Solve for 'y'
