a. Your answer is correct.
b. Divide the given value of sigma by √n where n = sample size = 7. Then perform the same calculation you did for part a. The probabiilty is 0.4427.
Answer:
Step-by-step explanation:
During the first year, ABC's stock price starts at $100 and increases by 100%. This means that the amount by which the stock increased would be
100/100 × 100 = $100
The new price of the stock would be 100 + 100 = $200
During the second year, its stock price goes down 25% from its price at the end of the first year. This means that the amount by which the stock reduced is
25/100 × 200 = 0.25 × 200 = $50
Therefore, the price of the stock, in dollars, at the end of the second year is
200 - 50 = $150
1) the small and large triangles are similar, then we can write:
x/24 = 8/18
Cross multiplication → 18x = 24.8 → 18x = 192 and x = 192/18
and x = 32/3 Or 10 ²/³
2) Δ ABC is similar to Δ EDC Since:
∠A = ∠D = 90°
∠C is common
