Answer:
Total area= 207 ft^2
Step-by-step explanation:
You can divide the figure to make 2 big rectangles.
The first has a base of 15 ft and a height of 15 ft
A1 = b * h
A1= 15 ft * 9 ft A1= 135 ft^2
The second has a base of 12 ft and a height of 6 ft
A2= b*h
A2= 12 ft * 6 ft
A2= 72 ft^2
Total area= A1+A2= 135 ft^2 + 72 ft^2
Total area= 207 ft^2

Answer:
Step-by-step explanation:
P(1 defective)=P(from A and 1 defective)+P(from B and 1 defective)
=0.75*5C1(0.01)1(0.99)4+0.25*5C1(0.02)1(0.98)4 =0.75*0.0480+0.25*0.0922 =0.0591
hence P(lot from vendor A given 1 defective)=P(from A and 1 defective)/P(1 defective)=0.75*0.0480/0.0591=0.6097
P(lot from vendor B given 1 defective)=P(from B and 1 defective)/P(1 defective)=0.25*0.0922/0.0591=0.3903
