<u>We </u><u>have</u><u>, </u>
- Line segment AB
- The coordinates of the midpoint of line segment AB is ( -8 , 8 )
- Coordinates of one of the end point of the line segment is (-2,20)
Let the coordinates of the end point of the line segment AB be ( x1 , y1 ) and (x2 , y2)
<u>Also</u><u>, </u>
Let the coordinates of midpoint of the line segment AB be ( x, y)
<u>We </u><u>know </u><u>that</u><u>, </u>
For finding the midpoints of line segment we use formula :-
<u>According </u><u>to </u><u>the </u><u>question</u><u>, </u>
- The coordinates of midpoint and one of the end point of line segment AB are ( -8,8) and (-2,-20) .
<u>For </u><u>x </u><u>coordinates </u><u>:</u><u>-</u>
<u>For </u><u>y </u><u>coordinates </u><u>:</u><u>-</u>
Thus, The coordinates of another end points of line segment AB is ( -14 , 36)
Hence, Option A is correct answer
Answer:
(b)
Step-by-step explanation:
1 male named Bart (b)
3 females named Charlene(c), Diana(d), and Erin(e).
Since there is replacement, the possible samples are:
bb, bc, be, bd, cb, cc, cd, ce, db, dc, dd, de, eb, ec, ed, and ee.
Total Number of pairs = 16
Event of picking 2 males:bb
Event of 1 male:bc,cb,bd,db,be,eb
Event of picking 0 males:
cc, cd, ce, dc, dd, de, ec, ed, and ee.
b. The mean of the sampling distribution
c. No; the proportion of males is while the mean is
.
B. No, the sample mean is not equal to the population proportion of males. These values are not always equal, because proportion is an unbiased estimator.
