Tracy found the length of gf. her work is shown below.

16 = 2(2x)
16 = 4x; x = 4
8(4) = 32
gf = 2(32)
gf = 64
what error did tracy make?
she used ag = 2eg, but the correct statement is 2ag = ge.
she found that x = 4, but the correct value for x is 2.
she used gf = 2bg, but the correct statement is bg = 2gf.
she found that gf = 64, but the correct value of gf is 8.

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed

An incoming airplane is x miles due north from the control tower at an airport. a second incoming airplane is y miles due east of the same control tower. the shortest distance between the two airplanes is z miles. which of the following functions would best model the situation above?
