Answer:
$2.40
Step-by-step explanation:
First, you would do 22.70 minus 3.50, to get 19.20.
Then, you would divide 19.20 by 8, to get 2.4.
So, if each pineapple was the same price, each pineapple would be $2.40.
<span>It's 1/r!
nCr = n! / r!(n-r)!
nPr = n! / (n-r)!
If you divide the two you'd have:
n! / r! (n-r)! * (n-r)! / n! = 1/r!

Answer: bacteria 2
Step-by-step explanation:
Since the growth rates are modeled as : Bacteria 1: y = 4x
And Bacteria 2: y = 4x2
Where y represents the number of bacteria colonies and x represents the number of hours.
Let's plug in for the two models
By assuming x = 2 and x = 3
If x = 2
Bacteria 1 will be y = 8 and bacteria 2 will be y = 16
Based on these models, bacteria 2 is growing faster than bacteria 1 because the growth is exponential
