Standard form is y=Mx+b so first step is to isolate y:
Y=1/3(x+3)-11
Then use order of operations to simplify the x to a whole number. First multiply by three:
3y=x+3-33
Now combine like terms:
3y=x-30
Finally,
Divide to make y have a coefficient if one:
Y= 1/3x -10
First we calculate the z-score for this situation.

Finding <em>P</em>(x < 5.3) is the same as finding <em>P</em>(<em>z</em> < -0.8). Using a table of standard normal distribution and z-scores we see that the probability is 0.21186.
The answer is 0.60 because the sum of the shaded angles equals 145°, divided by 360° equals 0.60
