A city manager must predict the population growth of the city between the years 2000 and 2050 to
make plans for new business expansions and housing developments. To determine the population
growth, the city manager will use the formula y= a(b)x. What do the variables in this formula
represent?

y represents the population of the city
x represents the year
b represents the population in the year 2000
a represents the growth rate

y represents the population of the city
x represents the time in years since the year 2000
b represents the growth rate.
a represents the population in the year 2000

yrepresents the population of the city
x represents the time in years since the year 2050
b represents the number of new businesses and houses
a represents the population in the year 2010

y represents the population of the city
x represents 50 years
b represents the population in the year 2050
a represents the growth rate

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
