bitsy spider wants to climb up the inside of a one foot water spout. The itsy bitsy spider can climb 3 3/4inches each day before the rain comes down and washes her back 1 1/4inches each night. The next day the sun comes up and dries up all the rain and the itsy bitsy spider begins climbing again. Despite her discouraging progress, the itsy bitsy spider continues with this frustrating cycle until she makes it up and out of the water spout. How many days does it take the itsy bitsy spider to get out of the water spout? Show all your mathematical thinking.

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.
