Juan and alex are both saving money for college. juan saves $150 per month and currently has $2000 in the bank. alex saves $250 per month and has only $1000 in the bank. not counting the interest they will earn, how many months will it take until both boys have saved the same amount of money? •let m represent the # of months it takes juan and alex to save the same amount of money •let a represent the amount of money they will have after m months.
a. write an equation for the amount of money juan will have after m months.
b. write an equation for the amount of money alex will have after m months.
c. solve the two equations to determine the number on months it will take them to save the same amount of money. your solution will be (m,

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:
