Please help me!! A professional bowler is practicing for a tournament. On any given bowl, he has a 60 percent probability of getting a strike .

a) At the beginning of his practice, he likes to bowl until he fails to make a strike. How many times is he expected to bowl until he gets his first non-strike?

b) A perfect game consists of bowling 12 straight strikes. How likely is this bowler to bowl a perfect game?

c) In a game, which is 12 bowls, how likely is the bowler to get 9 or more strikes?

d) The bowler has pledged to give a certain amount to charity for every strike he gets during the tournament. He expects to bowl a total of 108 times over the course of the tournament. How much money should he give per strike if he wants to end up giving $1000 to charity?

The multiplication property of zero states that the product of any number and 0 is 0. what must be true about either a or b to make ab=0

How are sas and sss used to show that two triangles are congruent?

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
