You have an unfair coin that is designed to come up heads 80% of the time.

a.) what is the probability that you will have to flip the coin exactly three times to get the first head?

b.) on average, how many times must you flip it to get the first head?

c.) on average, how many times must you flip it to get the first tail?

d.) what is the probability that you must flip the coin four or more times to get the first tail?

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

hope this is what you were asking for!
