What important feature of the data is not revealed through the different measures ofâ variation? a. the measures of variation reveal nothing about how the numbers of manatee deaths are spread. b. the measures of variation do not reveal the difference between the largest number of manatee deaths and the smallest number of manatee deaths in the data. c. the measures of variation reveal nothing about the pattern over time?

c. Measures of variation reveal nothing about the pattern over time.

The measures of variation are the range, interquartile range, variance and standard deviation.

Variance and its square root, standard deviation measure the dispersion of data about the mean. They measure how spread out the data is from the mean.

Range is a measure of variation that shows the  difference between the largest and smallest values in the data.

However, measures of variation reveal nothing about the patterns over time. They treat a given data set as a whole and give numbers are applicable for the entire data set.

zeros are -3.2 and 3

Step-by-step explanation:

Use the graphing calculator to graph and find the zeros of the function

y = 2x^2 + 0.4x – 19.2

WE use graphing calculator to graph the equation y = 2x^2 + 0.4x – 19.2

Then we look at the points where the graph crosses x axis

zeros are the x values that where the graph crosses x axis

At x axis the y values are 0. so to get zeros we look at the x  values where y is 0

the graph is attached below

(-3.2,0)  and (3,0)

zeros are -3.2 and 3
