Answer:
Alien does not take the sample because alien choose the data of a Government's congress and congress contain less women.
On the other hand general population contain women greater than congress
So as compared to general population confidence interval is not representative.
The -2 at the end means that while the x remains constant, the y will be smaller - it shifts it 2 units down
the other change is that it's x+4 now, not x, and this shifts the graph left. (the value of function is now the same as previously when x was smaller)
the answer is B!
Order of operations
PEMDAS
There are no parenthesis
There are no exponents
Now, we do multiplication and division from left to right
(9x9) + 8 - (8/10)
=
81 + 8 - 0.8
Now, we do addition and subtraction from left to right
(81 + 8) - 0.8
89 - 0.8
=
88.2
Let’s go with 7.0 that is what I think it is
For number 3, C is the answer.
#4. D
the coefficient of x² is negative, so the graph opens downward.
the two zeros are (3,0) and (5,0)
cannot see the question when editing. I'll post it in the comments.
