6500=7x+5000
6500-5000=7x+5000-5000
1500=7x
1500/7≈214
x≈214
y=19·214+5000
y=9066
answer=9066 bacteria
Try as percentages so
7) 37.5%
8) 50%
9) 12.5%
10) 62.5%
11) 87.5%
12) 50%
13) 62.5%
14) 37.5%
15) 100%
6•6 = 36 - all possibilities in a roll of two dices
3&4 or 4&3 - two possibilites
Probability that one of the dice will be a 3 and the other a 4:
