I suspect you want the area under the standard normal curve to the left of z = -0.95.
On my calculator I typed in normal cdf(-100, -0.95) and got the result 0.171.
Problem 1) Line n is the line of symmetry (not line o) because we can fold the lower half to match up with the upper half. The folding line is over line n.
Problem 2) I agree. Nice work on getting the correct answer. The folding line is a vertical line through the center
Problem 3) It's hard to say for sure, but I think the top left corner is NOT reflective over any line of symmetry no matter how you rotate it. So I would uncheck that box. I agree with your other choices though. Great job with those.

Step-by-step explanation:
<em>The question is incomplete as the solution to part A (or part A itself) is not given. To solve this, I will assume a value to the supposes solution to part A.</em>
<em></em>
From the question:
1 square foot is sold at $3.
This implies that:
p square foot will be sold at $3p.
So, total sales can be calculated using:
Now assume that p is 10 square feet (from part A).
The total will be:
I am pretty sure the answer is 2,520.
from the given equation
X+Y=20-->i
X-Y=14--->ii
add eq i and eq ii
2x=34
x=17
putting the value of x=17 in eq i
17+y=20
then y = 3 so the right answer is
17 and 3
