A graph titled position versus time has an horizontal axis time (seconds) and a vertical axis position (meters). A straight line passes from 0 seconds, 0 meters to 5 seconds, 20 meters. Calculate the slope of the line on the graph using the formula:

m = m = v subscript 2 - v subscript 1 over x subscript 2 minus x subscript 1.

The slope of the line is
m/s.

In a ni-cd battery, a fully charged cell is composed of nickelic hydroxide. nickel is an element that has multiple oxidation states. assume the following proportions of the states: nickel charge proportions found 0 0.17 +2 0.3 +3 0.33 +4 0.5 (a) determine the mean of the nickel charge. enter the answer to 2 decimal places.(b) determine the cumulative distribution function of nickel charge.
