At one of new york’s traffic signals, if more than 17 cars are held up at the intersection, a traffic officer will intervene and direct the traffic. the hourly traffic pattern from 12: 00 p. m. to 10: 00 p. m. mimics the random numbers generated between 5 and 25. (this holds true if there are no external factors such as accidents or car breakdowns.) scenario hour number of cars held up at intersection a noon−1: 00 p. m. 16 b 1: 00−2: 00 p. m. 24 c 2: 00−3: 00 p. m. 6 d 3: 00−4: 00 p. m. 21 e 4: 00−5: 00 p. m. 15 f 5: 00−6: 00 p. m. 24 g 6: 00−7: 00 p. m. 9 h 7: 00−8: 00 p. m. 9 i 8: 00−9: 00 p. m. 9 based on the data in the table, which scenarios would require a traffic cop? a, b, and e b, d, and f g, h, and i a, c, and e

The answer is : B,D and F will require a traffic cop

Step-by-step explanation:

To find scenarios which require a traffic cop or not we need to find the no. of cars standing up at the intersection

So, no. of cars standing at the intersection of three traffic lights = minimum of no. of cars at all the three traffic lights

= min { 16,24,15 } = 15 < 17 . So, no traffic cop required.

= min { 24,21,24 } = 21 > 17 . So, traffic cop is required

= min { 9,9,9 } = 9 < 17 . So, no traffic cop required

= min { 16,6,15 } = 6 < 17 . So, no traffic cop required

Hence, the scenario which requires a traffic cop is one at which intersection of no. of cars is greater than 17 so our required scenario is B,D and F

15.5

step-by-step explanation:

5

∑

n = 1

substitute n = 1, 2, 3, 4, 5 and sum the terms

= + + + 2² + 2³

= 0.5 + 1 + 2 + 4 + 8

= 15.5
