Quadratic Equasions Question: Alfonso drives a red Nissan Micra. The total stopping distance (tsd) for the car, measured in metres, is given by the formula:

tsd = reaction time (rt) + braking distance (bd)

Alfonso's reaction time is given by the formula rt = ¼ v and the car's braking distance is given bd = ⅛ v² where v is his speed measured in metres per second. whilst driving around town, Alfonso is forced to perform an emergency stop; his total stopping distance is 15 metres. calculate the speed Alfonso was travelling, give your answer in km/h.

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
