Answer:
125.5
Step-by-step explanation:
I made the shape in to 2 seperate shapes
the rectangle:8 times 10 is 80
Trapezoid: A=a+b/2(h)
3+10/2(7) is 45.5
so 80+45.5= 125.5
Answer:
11/40 + 1/4 + 1/20
Step-by-step explanation:
Draw a Venn diagram: (as shown)
Consumer Ed. : 22-4=18
French : 20-4=16
Neither : 80-18-16-4=42
Using probability notation where P(A) means probability of event A occurring.
P(Consumer Ed.) = 22/80
P(French) = 20/80
P(Both) = 4/80
<em>'or ' </em>in the question means you add.
=> 22/80 + 20/80 + 4/80
=> 11/40 + 1/4 + 1/20
