(a bodybuilder loads a bar with 550 newton's (-125 pounds)of weight and pushes the bar over her head 10 times. each time he lifts the weight 0.5 meters. how much work (j) does she do? ) if she pushes the bar 10 times in 20 seconds, how much power did she use?

The ph level of a blueberry is 3.1 what is the hydrogen-ion concentration [h+] for the blueberry

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
