An ambulance travels back and forth at a constant speed along a road of length l. at a certain moment of time, an accident occurs at a point uniformly distributed on the road. [that is, the distance of the point from one of the fixed ends of the road is uniformly distributed over p0, lq.] assuming that the ambulance’s location at the moment of the accident is also uniformly distributed, and assuming independence of the variables, compute the cumulative distribution function of the distance of the ambulance from the accident.

answer: i think it's a

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true

a. positive: 2 or 0; negative : 2 or 0; complex: 4or2or0
