Henrik's Options.  Assume Henrik buys a call option on euros with a strike price of $1.25001.2500 = euro€1.00 at a premium of 3.80 cents per euro ($0.03800.0380 per euro€) and with an expiration date three months from now. The option is for 100 comma 000100,000 euros. Calculate Henrik's profit or loss should he exercise before maturity at a time when the euro is traded spot at strike prices beginning at $1.121.12 = euro€1.00, rising to $1.301.30 = euro€1.00 in increments of $0.030.03. Question content area bottom Part 1 The profit or loss should Henrik exercise before maturity at a time when the euro is traded spot at $1.121.12/euro€ is $enter your response here. (Round to the nearest cent and indicate a loss by using a negative sign.) Part 1 Cachita Haynes. Cachita Haynes works as a currency speculator for Vatic Capital of Los Angeles. Her latest speculative position is to profit from her expectation that the U.S. dollar will rise significantly against the Japanese yen. The current spot rate is ¥119.00119.00 = $1.00. She must choose between the following 90-day options on the Japanese yen: LOADING... . a. Should Cachita buy a put on yen or a call on yen? b. What is Cachita's breakeven price on the option purchased in part (a)? c. Using your answer from part (a), what is Cachita's gross profit and net profit (including premium) if the spot rate at the end of 9090 days is ¥140.00140.00 = $1.00?

(D) Two-sample proportion z-test (E) Chi-square test of association 2. A type of insect is being studied that displays aggression towards some others of its own species. A researcher wishes to determine if there is a difference in aggression level between others from its own colony and from different colonies. The researcher puts the insects together in pairs. A random sample of forty-nine pairs where each pair is of the same colony was observed. Also, a separate random sample of 55 pairs where each pair had two from different colonies. The results are displayed in the table. A chisquare test for homogeneity was performed resulting in \( \chi^{2}=7.638 \). The expected counts are also displayed in the table in parentheses. Which of the following statements follows from these results? \begin{tabular}{|l|c|c|c|} \hline & Aggressive & Nonaggressive & Total \\ \hline Same colony & \( 40(33.5) \) & \( 9(15.5) \) & 49 \\ \hline Different colonies & \( 31(37.5) \) & \( 24(17.5) \) & 55 \\ \hline Total & 71 & 33 & 104 \\ \hline \end{tabular} (A) \( \chi^{2} \) is not significant at the 0.05 level. (B) \( \chi^{2} \) is significant, \( 0.01<p<0.05 \); the counts in the table suggest that insect pairs from the same colony are less likely to be aggressive than insect pairs from different colonies. (C) \( \chi^{2} \) is significant, \( 0.01<p<0.05 \); the counts in the table suggest that insect pairs from different colonies are less likely to be aggressive than insect pairs from the same colony. (D) \( \chi^{2} \) is significant, \( p<0.01 \); the counts in the table suggest that insect pairs from the same colony are less likely to be aggressive than insect pairs from different colonies. (E) \( \chi^{2} \) is significant, \( p<0.01 \); the counts in the table suggest that insect pairs from different colonies are less likely to be aggressive than insect pairs from the same colony. 3.

Why is my A wrong? And I need help with D, please. The rocket's position measured from the center of the Earth is given by: y = RE^3 / (2/3RE^3) where R is the radius of the Earth (6.38 * 10^6 m) and g is the constant acceleration near the Earth's surface (9.8 m/s^2). a) Derive expressions for V and a. Use the following equations: V = dy/dt (velocity) a = d^2y/dt^2 (acceleration) Do not substitute numerical values, use variables only. b) Plot y, V, and a as functions of t. Choose suitable values for R and g. c) When will the rocket be at y = R/2? d) What are V and a when y = R/2? Express your answers in vector form.
