Five pulse rates are randomly selected from a set of measurements. the five pulse rates have a mean of 71.0 beats per minute. four of the pulse rates are 53, 79, 75, and 57. a. find the missing value. b. suppose that you need to create a list of n values that have a specific known mean. some of the n values can be freely selected. how many of the n values can be freely assigned before the remaining values are determined?

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
