E.coli Bacteria present in one CFU at 9:00 pm = 1.07 X 109 bacteria and E.coli at 11:00 am = 1 generation time. That means 2.66X 10^ 9 cells per 1 CFU.

The average CFU in probiotics is between 1 and 10 billion CFUs per serving. To find out the number of CFU in the sample then the number of colony forming units on thee countable plate is multiples by 1/FDF. For example when the countable place has 200 colonies then 200 CFU and the FDF was 1/4000.

CFU measures the viable cells.High number of E.coli bacteria in water indicates that contaminated by feces. and it increasing the risk of exposure to pathogens that causes illness.

Drag the tiles to the correct boxes to complete the pairs.
Darina [25.2K]

After matching each set of values of a function to the pair of points that satisfy the function, we get

1-4

2-2

3-1

4-3

(4,3) and (6.7) rate of change = 2, and initial value = -5

k= 7-3/6-4 = 2, y=2x-5

(2,10) and (5, 19) rate of change=3, and initial value = 4

k= 19-10/5-2 = 9/3 = 3, y=3x+4

(2,5) and (5.2)→ rate of change = -1, and initial value = 7.

k= 2-5/5-2 =  -3/3 = -1, y= -x+7

(2.4) and (4,3) →→ rate of change = -0.5, and initial value =5

k= 3-4/4-2 = -1/2 =-0.5, y=-0.5x+5

The set of input values and the set of output values for a function each have their own names. The domain of the function is the collection of input values. The range of the function is the collection of output values.

Correct question: Drag the tiles to the correct boxes to complete the pairs. Match each set of values of a function to the pair of points that satisfy the function. rate of change = -1, and initial value = 7 rate of change = 2, and initial value = -5 rate of change = -0.5, and initial value = 5 rate of change = 3, and initial value = 4 (4, 3) and (6, 7) arrowRight (2, 10) and (5, 19) arrowRight (2, 5) and (5, 2) arrowRight (2, 4) and (4, 3) arrowRight
