Answer:
All the events in the sample space that are not are the part of the specified event are All called the complement of the event.
Step-by-step explanation:
Suppose tossing a coin, the sample space here is {H,T}.
Now, if the event is getting a head ,
so here T is not the part of the sample space and is called as complement of the event.
Therefore, all the events in the sample space that are not are the part of the specified event are All called the complement of the event.
Answer:
a) 
b) 86.5 years
Step-by-step explanation:
All values are rounded to 2 decimal places
a) We can find line by using y =mx+b

Therefore the line of best fit is 
b) We can do this by using the formula of the best fit line to estimate the life expectancy of someone born in 2005

Therefore the estimated life expectancy of someone born in 2005 is 86.5 years
PS. Please give brainliest answer this was a lot of working out
3(x + 5) = -4x + 8
3x + 15 = -4x + 8
3x + 4x = 8 - 15
7x = - 7
x = -7/7
x = -1
this equation has exactly 1 solution
