The probability that a male professional golfer make a hole-in-one is 1/2780. Suppose 10 professional male golfers play the sixth hole during a round of golf. Let Y represent the number of these 10 men who make a hole-in-one on the sixth hole. Calculate the probability that none of the 10 golfers makes a hole-in-one on the sixth hole. (Round your final answer to the ten-thousandths place.)

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

$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

the answer is 40.
