Assume that police estimate that 30% of drivers do not wear their seatbelts. They set up a safety roadblock, stopping cars to check for seatbelt use. They stop 25 cars during the first hour. a. Find the mean, variance, and standard deviation of the number of drivers expected not to be wearing seat belts. Use the fact that the mean of a geometric distribution is μ= 1 p and the variance is σ2= q p2. b. How many cars do they expect to stop before finding a driver whose seat belt isn't buckled

three-fourths of an hour

36÷48=0.75

the dots mean that it has infinitely more numbers behind it

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
