The slipperiness of a floor (denoted by sss) can be defined as a function of the number of banana peels (denoted by ppp) and the area of the floor (denoted by aaa) using this formula:

s = \dfrac{p}{a}s=

a

p



s, equals, start fraction, p, divided by, a, end fraction

area of the floor is measured in \text{m}^2m

2

start text, m, end text, squared.

select an appropriate measurement unit for slipperiness of a floor

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.
