Three minutes after a skydiver opens his parachute, he has descended 2,850 feet. after 5 minutes, he has descended 4,750 feet. if he descends at a constant rate throughout, how many feet did he descend in one minute?

Calculate the slope

(2850-4750)/(3-5)= -1900/-2=950

So in one minute, he descended 950 feet

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
