Use Bayes' rule to find the indicated probability.Two stores sell a certain MP3 players. Store A has 34% of the sales, 5% of which are of defective items, and store B has 66% of the sales, 1% of which are of defective items. The difference in defective rates is due to different levels of pre-sale checking of the product. A person receives a defective item of this product as a gift. What is the probability it came from store B?
A. 0.275
B. 0.22
C. 0.5667

Solve the problem.A projectile is fired from a height of 7.3 feet with an initial velocity of 148 ft/sec at an angle of 56° with the horizontal. The parametric equations for the path of the projectile are x = (148 cos 56°)t, and y = 7.3 + (148 sin 56°)t - 16t2,where x and y are in feet and t is in seconds. Find the height of the projectile after 4 seconds. Round your answer to the nearest tenth of a foot.
A. 242.1 ft B. 434.1 ft C. 234.8 ft D. 331 ft
