4. To the nearest whole number what is the population density in people per square mile for Florida in 2014? To the nearest whole number how much did the population density in people per square mile increase from 2010 to 2014?
5.8/100 = x/18,801,310 ==================================>
x = 1,090,475.98
=================================>
18,801,310 + 1,090,475.98 = 19,891,785.98 population at 2014
=============================>
19,891,785.98/53,625 =
about 371 people per square mile in 2014

18,801,310/53,625 =
about 351 people per square mile in 2010
=================================>
371 - 351 = 20 people per square mile increase from 2010 to 2014
I got 22 because if u do 20 multiplied by 10% that gives u 2 which u then add onto the 20 to get the starting price. 10% of 22 is 2 and then 22-2 = 20 (if u we’re doing it from the starting price)
The score of 96 is 2 standard deviations above the mean score. Using the empirical rule for a normal distribution, the probability of a score above 96 is 0.0235. Therefore the number of students scoring above 96 is given by:
