Answer: (3,-2)
Step-by-step explanation:
new system:
add.
plug in -2 for y
system:
Subtract what is to the right of the equal sign form both side of the equation but any way the answer is 0
Divide -3
-3/-3a = 15/-3
a = -5
In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71
=0.71 estimated
margin of error = distance from estimate point lower/ upper bound
This interval will be twice margin error
(0.82-0.6)/2 = 0.11
How far is 0.82 from 0.71 ??
=0.11=11%
23/26 which equals about 88%
There is an 88% chance she will not get picked.
