ANSWER
D. Ellipse;

EXPLANATION
The given equation is

Dividing through by 9 gives

This is the equation of an ellipse centered at the origin.
If this ellipse has been translated, so that its center is now at (-1,3), then the equation of the translated ellipse becomes

We multiply through by 9 to get,

Expand to obtain;

Expand to obtain;

Regroup and equate to zero to obtain;

The answer would be 1 3/4.
Split 7 into 4+3. We now have: (4+3)/4. This is the same as 4/4+3/4. This is 1+3/4. Now for mixed numbers<span> remove the +.

Answer:
H0: p(1980) = p(2010) ; H1 : P(1980) > P(2010)
0.02
Step-by-step explanation:
Given that:
Sample size in both 1980 and 2010 = 1000 samples :
Proportion in favor :
P(1980) = 0.66
P(2010) = 0.64
To test the hypothesis :
Null hypothesis :
Proportion in favor are the same in both years
Null hypothesis = H0 = p(1980) = p(2010)
Alternative hypothesis :
Proportion in favor in 1980 is greater than that in 2010
Alternative hypothesis = H1 : P(1980) > P(2010)
The sample statistic :
P(1980) - p(2010)
0.66 - 0.64
= 0.02
