Highway patrol officers measure the speed of automobiles on a highway using radar equipment. The random variable in this experim
ent is speed, measured in miles per hour. This random variable is a _____. a. discrete random variable b. continuous random variable c. complex random variable d. None of the answers is correct.
Speed is a common continuous variable and the value is always random.
It is continuous because there is always another speed value between two speed values. For example, a car travelling at the rate of 50 mils per hour will either increase or decrease its speed at a continuous rate. No speed can drop suddenly form 50mph to 20mph.
It is random because although there might be speed limit, the speed recorded by the Highway patrol officer willl always be random in value.
First we have to see in both cases what is the cost of one ticket in the fist case 12.5/5=2.5 in the second case 20.16/8=2.52 therefore 5 tickets for 12.5 is the better deal
