The answer is 6.6 because it’s the only number between 6.5 and 6.7 so 6.6 is your answer
Answer: WZ=10, YZ=15
Step-by-step explanation:
<h3>Straightforward Solution</h3>
The long way around is to compute the return from each investment and relate the sum of those returns to the toal investment.
You have invested $33×100 = $3300 in clooney. You expect a return of 20%×$3300 = $660 on that investment.
You have invested $42×100 = $4200 in marx. You expect a return of 12%×$4200 = $504 on that investment.
Your total expected return is $660 + 504 = $1164. Your total investment is $3300 + 4200 = $7500. Thus, the return on your investment is expected to be
... $1164/$7500 = 0.1552 ≈ 15.5% . . . . matches choice a.
<h3>Alternative Solution</h3>
Since the same number of shares is involved in both investments, you can weight the expected return percentages by the ratio of share price to total of share prices:
expected return = (33/75)×20% + (42/75)×12%
... = 8.80% + 6.72% = 15.52%
My answer was 56/27. Here is the work I did.
Step-by-step explanation:
As we know that
- The circle center is equidistant from all three points, the distance being the circle radius.
- Any point equidistant from two points must lie on the perpendicular bisector of the line segment which join those two points.
- Which is, on the line through the midpoint of the line segment, perpendicular to the line segment.
The perpendicular bisector of the line segment joining the points (1, 1) and (1, 3) will be:

The perpendicular bisector of the line segment joining the points (1, 3), and (9, 2) will be:

These intersect at the center of the circle (5, 2).
The distance between (1, 1) and (5, 2) will be:






So the equation of the circle can be written as:
