Answer: 
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where
is the sample mean and ME is the margin of error .
Given : The sample mean : 
Margin of error : 
Then , the range of values (confidence interval) likely to contain the true value of the population parameter will be :-

Hence, the range of values likely to contain the true value of the population parameter =

Answer:
A' = (-6, -2)
Step-by-step explanation:
A is at ( -3,-1)
The dilation factor is 2 so multiply by 2
A' = (-3*2, -1*2)
A' = (-6, -2)
Answer:
(X+6)x(X-3)
Step-by-step explanation:
X^2+6X-3X-18
Xx(X+6)-3(X+6)
(X+6)x(X-3)
big X is the variable
small x is multiplication sign
