A cubic satellite with dimensions is described in Fig. Q1. Assuming that the origin of the moving coordinates xyz is fixed to the center G of the satellite as shown in the figure and point G is fixed relative to the primary coordinates XYZ. The satellite rotates relative to xyz system at an angular velocity $\omega = -5i + 2j + 4k$ (rad/s) Meanwhile the coordinates xyz is rotating relative to the primary reference XYZ with an angular velocity $\Omega = 10i + 4j + 6k$ (rad/s). Determine: i. The velocity of corner P of the satellite relative to the primary coordinates XYZ. ii. The rotation acceleration of the satellite relative to the primary coordinates XYZ. iii. The acceleration of corner P of the satellite relative to the primary coordinates XYZ.

Consider a sample of 45 football games, where 32 of them were won by the home team. Use a 0.05 significance level to test the claim that the probability that the home team wins is greater than one-half. Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. $H_0: p > 0.5$ $H_1: p = 0.5$ B. $H_0: p = 0.5$ $H_1: p < 0.5$ C. $H_0: p = 0.5$ $H_1: p \neq 0.5$ D. $H_0: p = 0.5$ $H_1: p > 0.5$ Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. A. Fail to reject $H_0$. There is not sufficient evidence to support the claim that the probability of the home team winning is greater than one-half B. Reject $H_0$. There is not sufficient evidence to support the claim that the probability of the home team winning is greater than one-half
