A biologist wrote a program to simulate the population of
a sample of bacteria. The program uses the following
procedures.
Procedure CallExplanationInitialPopulation ()Returns the
number of bacteria at the start of the
simulationNextPopulation (currPop)Based on the current
value of currPop, returns the number of bacteria after one
hour
Code for the simulation is shown below.
hours ←← 0
startPop ←← InitialPopulation ()
currentPop ←← startPop
REPEAT UNTIL ((hours ≥ 24) OR (currentPop ≤ 0))
{
currentPop ←← NextPopulation (currentPop)
hours ←← hours + 1
}
,DISPLAY (currentPop - startPop)
Which of the following are true statements about the
simulation?
The simulation continues until either 24 hours pass or the
population reaches 0.
The simulation displays the average change in population
per hour over the course of the simulation.
The simulation displays the total population at the end of
the simula - correct answer- A

, A color in a computing application is represented by an
RGB triplet that describes the amount of red, green, and
blue, respectively, used to create the desired color. A
selection of colors and their corresponding RGB triplets
are shown in the following table. Each value is
represented in decimal (base 10).
