In ideal conditions, 200 colony-forming units (cfu) of E. coli can grow to 400 cfu in 20 minutes, to 800 cfu in 40 minutes, and
kvasek [131]

Answer:

(a)Yes, it is an exponential function.

(b)P(t)=200\cdot 2^{t/20}

Step-by-step explanation:

(a)A population grows exponentially if it increases by a common ratio(called the growth ratio). We can see from the given information that the population of E.coli doubles every 20 minutes, therefore it is an exponential growth with a growth ratio of 2.

(b)The population, P(t) at any time t of an initial population, P_o  with a growth ratio of r over a period k can be modeled using the function:

P(t)=P_o\cdot r^{t/k}

In this Case:

P_o=200

Growth rate,r=2

Growth Period,k=20 minutes

Therefore, the equation that models the function is:

P(t)=200\cdot 2^{t/20} , t is in minutes

rewona [7]
  put the amount of $8 a pound chocolate as say it as x
 As the total number of pounds is 20
so the amount of $3 a pound chocolate must be <span>20−x
so it will be</span>.
8x + 3(20 - x) = 5(20)
so correct option is C

Joe's company sold insurance policies over the phone. Last month, 2 employees sold three hurricane policies, 6 employees sold tw
ehidna [41]

The probability that the employee sold two hurricane policies or sold one hurricane policy is 15/17.

According to the statement

Number of employees who sold three hurricane policies is 2

Number of employees who sold two hurricane policies is 6

Number of employees who sold 1 hurricane policies is 9

SO,

The total number of employees is 2+6+9=17.

The number that sold two hurricane policies or sold one hurricane policy is 6+9=15,

so the Probability = Total number of policies sold / total number of employees

Probability = 15/17

So, The probability that the employee sold two hurricane policies or sold one hurricane policy is 15/17.
