Step-by-step explanation:
<u>Step 1: Find the probability in 6 cars</u>
6 * %80 or 6 * 0.8
4.8
Answer: Option B, At least three will have the transponder
I don’t really understand but this are the answer for both the first one: x>-2 second: x<-2
Width is x.
Length is (x + 1).
Area = length*width
56 = x(x+1)
x² + x - 56 = 0
(x+8)(x-7)=0
x = - 8, or x = 7
"- 8" is impossible for width.
So, width x = 7
Length = (x+1) = 7+1 = 8
The volume of a cone is V=(1/3)•pi•r^2•h
now you plug in your given values
V=(1/3)•pi•2^2•5
the final answer is (20/3)pi
