suppose that the world’s current oil reserves is R= 2150 billion barrels. If, on average, the total reserves is decreasing by 20 billion barrels of oil each year answer the following: A). give a Linear equation for the total remaining oil reserves, R, in billions of barrels, in terms of T, the number of years since now. B.) seven years from now, the total oil reserves will be __blank__ billions of barrels. C). if no other oil is deposited into the reserves, the worlds oil reserves will be completely depleted (all used up) approximately __blank__ years from now. (round your answer to two decimal places)

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

The formula for the volume of a right square pyramid is given below, where a is the side length of the base and h is the height.

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean
