Answer:
Return of investment = 44.5%
Step-by-step explanation:
Number of shares purchased by Tamara = 1500
Offer price per share = 7. 08
Total amount spent on purchasing shares = 1500 × 7.08 = 10620
Dividend receive per share = 0.21
Total dividend received on 1500 shares = no. of shares × dividend received per share
Total dividend received = 1500 × 0.21 = 315
Selling price per share = 10.02
Amount received by Tamara by selling the investment = no. of shares × selling price per share
Amount received by Tamara by selling the investment
= 1500 × 10.02
= 15030
Now, Net profit received on investment = S.P of Investment + Dividend received - C.P of investment
Net profit = 15030 + 315 - 10620 = 15345 - 10620 = 4725
Return on investment = 
=
≈ 44.5 %
A. -5 < y < -3 is the correct answer.
Answer: The value of x=1.
Measure of CD =1 unit.
Step-by-step explanation:
Given: Segment EC bisects segment AD at C.
That means , EC divided AD into two equal parts AC and CD,
i.e.
Also it is given that
and 
then, we have

So, the value of x=1.
Now, CD = AC = 4(1)-3 =4-3 =1 unit.
Hence, Measure of CD =1 unit.
X=1, x=-7 would be the correct answer.
