John conducted an experiment to test whether heat had an effect on a certain type of bacteria. He collected approximately 800 specimens of bacteria. After exposing them to 100º heat, John noticed that the bacteria colony was losing half of its population every hour. Complete the chart below to show how much bacteria was left each hour, then graph.

I am not all the way sure and don't want to Guide you in the wrong direction, so I am going to let someone else answer. The chart should be right though.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
