In these kind of problems, it's always the best to just draw it. There are "formulas" to calculate this, but it's better to know intuitively.
Midpoint, as the name suggests is the point that is exactly halfway between two points. To find a midpoint in one dimension, we would take an average between those two points.
Example: Number exactly halfway between 8 and 16 is

We can do the same for two dimensions, it just means we'll have to calculate both for x-values and y-values
Midpoint
Answer:
The top one is, and the bottom isn't

Answer:
97%
Step-by-step explanation:
for such a question we can use the percentage numbers like real unit numbers, as we need to analyze just the percentage numbers and align them with another percentage number with the result of another percentage number.
so, we just use the percentage numbers and deal with mean values and such like with real unit numbers.
therefore we need to find x
(79 + 92 + 71 + 86 + x) / 5 = 85
as the sum of all numbers divided by the number of measurements is the mean value.
and so,
79 + 92 + 71 + 86 + x = 425
328 + x = 425
x = 97
so, the next site must be 97%, so that the average for the 5 surveys will be exactly 85%
