Rayovac type-d batteries have a "continuous use-life" that is approximately normally distributed with mean 21 hours and standard deviation 1.38 hours. duracell type-d batteries have "continuous use-life" that is approximately normally distributed with mean 24 hours and standard deviation 2.13 hours. find the probability (to four places after the decimal) single rayovac battery lasts under 22 hours: mean "continuous use-life" of 4 randomly selected rayovac batteries is less than 22 hours: mean "continuous use-life" of 16 randomly selected rayovac batteries is less than 22 hours: mean "continuous use-life" of 64 randomly selected rayovac batteries is less than 22 hours: single duracell battery lasts under 22 hours: mean "continuous use-life" of 4 randomly selected duracell batteries is less than 22 hours: mean "continuous use-life" of 9 randomly selected duracell batteries is less than 22 hours: mean "continuous use-life" of 25 randomly selected duracell batteries is less than 22 hours: randomly selected rayovac battery lasts longer than a randomly selected duracell battrey: random samples of four of each kind, the rayovac batteries have a longer mean "continuous use-life" than do the duracell batteries:

Stefano accidentally dropped his sunglasses off the edge of a canyon as he was looking down. the height, h(t), in meters (as it relates to sea level), of the sunglasses after t seconds, is shown in the table. during its descent, the pair of sunglasses passed by a climber in the canyon 6 seconds after stefano dropped them. to the nearest meter, what is difference in elevation between stefano and the climber? 166 meters 176 meters 230 meters 240 meters its b.176 i took the test 166 is wrong and 176 is correct
