Henrietta did an experiment. She started out with 700 bacteria cells. She found that the growth rate of the bacteria cells was 5
poizon [28]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have a exponential function of the form

y=a(b^x)

where

y ---> is the population of bacteria

x ---> the number of hours

a is the initial value or y-intercept

b is the base of the exponential function

r is the rate of change

b=(1+r)

we have

a=700\ bacteria

r=5\%=5/100=0.05

so

b=1+0.05=1.05

substitute

y=700(1.05^x)

For x=20 hours

substitute in the equation and solve for y

y=700(1.05)^{20} =1,857\ bacteria

An experimenter is studying the effects of temperature, pressure, and type of catalyst on yield from a certain chemical reaction
irga5000 [103]

Answer:

90

12

0.0154

Step-by-step explanation:

a) #Possible experimental run=#Temp x #pres x #cat=3x5x6=90

b) #Possible experimental run=(Temp. lowest) x 2.pres x #cat=1x2x6=12

c) C="different catalyst is used on each run"

In the first, I can choice 6 of 6 catalysts, in the second 5 of 6,...

then: P(C) = 6/6 x 5/6 x 4/6 x 3/6 x 2/6 x 1/6 = 5/324 = 0.0154
