Answer:
p1.....area=lb=9×6=54in^2
p2....area=1/2bh
=14×9/2=7×9=63in^2
To solve this you need to make all of the percentages for the scores go back 2 decimals. For example: 82 --> 0.82
Next you multiply the decimal by the percent on the test.
0.90 × 75 = 67.5
0.95 × 10 = 9.5
0.82 × 15 = 12.3
Finally you add all of them up and get an answer.
67.5 + 9.5 + 12.3 = 89.3

The median is 2 1/2 which is question B
Answer:
(2a, b )
Step-by-step explanation:
Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[
(x₁ + x₂ ),
(y₁ + y₂ ) ]
Here (x₁, y₁ ) = N(2a, 2b) and (x₂, y₂ ) = P(2a, 0), thus
midpoint = [
(2a + 2a),
(2b + 0 ) ] = (2a, b )

21
