Answer:
(a). 15
(b). 78
Step-by-step explanation:
Growth of the population of a fruit fly is modeled by
N(t) = 
where t = number of days from the beginning of the experiment.
(a). For t = 0 [Initial population]
N(0) = 
= 
= 
= 15
Initial population of the fruit flies were 15.
(b).Population of the fruit fly colony on 11th day.
N(11) = 
= 
= 
= 
= 
= 77.82
≈ 78
On 11th day number of fruit flies colony were 78.
Answer:
C
Step-by-step explanation:
Is is a one-tailed test
P(z < 2.45) = 0.9929

Answer:

Step-by-step explanation:
Represent Alice with A, her friend with F and you with Y.
From the question, we have:

--- Twice as much Alice means 2 times Alice's earnings
--- 2 less than her friend
Required
Determine the total amount

Substitute
for A in


Substitute
for F in 

The total amount is calculated by adding the earnings of Alice, her friend and you



<em>Hence, the total earnings is 5d - 2</em>
