Answer: 0.042
Step-by-step explanation:
Point estimate of the difference between the two population proportion 
:-
, where 
and 
are sample proportions.
Given : In 1991 survey , The proportion of adults were current smokers =25.6%
i.e. 
In 2003 survey , The proportion of adults were current smokers = 21.4%
i.e. =0.214
Then , the point estimate of the difference between the proportion of current smokers in 1991 and the proportion of current smokers in 2003 :-
Hence, a point estimate of the difference between the proportion of current smokers in 1991 and the proportion of current smokers in 2003= 0.042
Answer: w + y = 180 degrees
Step-by-step explanation: The opposite angles in a cyclic quadrilateral are supplementary.
Answer:
A: if you cut it parrallel to the base, it will take the shape of the base, and the base is a rectangle, so it will still be a rectangle.
B: if you cut it perpendicular to the base, it will take the shape of the side face, making it a square
The answer is A assuming that the 7 is negative cause its on the left side of the 0 but I am positive the answer is A
Step-by-step explanation:
Even two points are enough to plot a line. Just pick two points (x1,y1), (x2,y2) that satisfy the equation 2y=3x+11, for example x=1,y=7 and x=0,y=5.5.
Then plot them on the plane, and connect the two dots to get your line.
