Bactena population doubles n sze every 5 hours. after 5 hours, the sample contains 2,000 bacteria which equation best models y. the population size after x hours?

Step-by-step explanation:

It is given that A bacteria population doubles in size every 5 hours. After 5 hours, the sample contains 2,000 bacteria.

and also Y=populations size and x=number of hours.

so at x=0 , Y=1000 and after 5 hours x=5 ,Y=2000. and after 5 more hours

at x=10, Y=4000

so we see that it is doubling every 5 hours i.e. the Equation will be like this

where  x= multiple of 5 years.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
