You need to a table of the standard normal cumulative distribution
Here is one:

0.2743 is what I see
Combine the x terms:
11x-10=180
Add Both sides by 10:
11x=190
Divide both sides by 11:
X=190/11
9514 1404 393
Answer:
D. (4, -6)
Step-by-step explanation:
Since the heights of both triangles are the same (CD), their areas are proportional to their bases. That is ...
AC : CB = 3 : 4
In terms of coordinates, ...
4(C -A) = 3(B -C) . . . . multiply the ratios by 4(CB)
4C -4A = 3B -3C . . . .simplify
7C = 4A +3B . . . . . . . isolate C
C = (4A +3B)/7 . . . . . divide by 7
C = (4(1, -9) +3(8, -2))/7 = (28, -42)/7 . . . . substitute given coordinates
C = (4, -6)
For the Jet one the answer should be 450 but its not on there
