Which bacteria sample (A or B) had a smaller initial population? What was that value?

zubka84 [21]

Answer:

B has a smaller initial population of 500

Step-by-step explanation:

Given

See attachment for complete question

Required

The bacteria with the smaller initial population

The initial population is at x = 0

For bacteria A;

$A(x) = 600$ when $x = 0$

For bacteria B, we have:

$B(x) = 500(2)^x$

Substitute 0 for x

$B(x) = 500(2)^0$

$B(x) = 500*1$

$B(x) = 500$

So; when x = 0

$A(x) = 600$ and $B(x) = 500$

Because; 500 < 600

We can conclude that B has a smaller initial population of 500

A car license plate is made up of 7 letters or numbers, where the numbers are whole numbers 0 through 9.

Simora [160]

Answer:

0.28

Step-by-step explanation:

To know the probability we first need to know the total number of choices for each character in the license plate. Since there are a total of 10 possible numbers (0-9) and 26 letters in the English Alphabet. Then this means that each character has a total of 36 possible choices. Out of these 36 only 10 are numbers, therefore the probability of the first character being a number is

$\frac{10}{36}$ or 0.2777

If we rounded the decimal to the nearest hundredth it would be 0.28
