Yes it is because of the chimney
Answer:
P = 1.214
Step-by-step explanation:
Draw a normal probability curve.
Find the z score which comes out to be 0.18 (0.181578947)
look for the probability in the table.
look across 0.1 and under 8.
Get the probability and add 0.5 to it
so rhats:
0.714 + 0.5 = 1.214
5/6*x + 2= 4/5*x -3
5/6*x - 4/5*x = -3 -2
x*(5/6-4/5)= -5
x*(25/30-24/30)=-5
x*1/30= -5
x/30=-5
x= -30*5
x= -150
