Answer:

Below.

Step-by-step explanation:

The center is at (2, -3) and the radius is 2.

The general form for a circle is

(x - h)^2 + (y - k)^2 = r^2    where (h, k) is the center and r = the radius.

So here the equation is:

(x - 2)^2 + (y + 3)^2 = 4.

A bacteria culture begins with 15 bacteria which double in amount at the end of every hour. How many bacteria are grown during t
elixir [45]
We use P = i•e^rt for exponential population growth, where P = end population, i = initial population, r = rate, and t = time
P = 2•i = 2•15 = 30, so 30 = 15 [e^(r•1)],
or 30/15 = 2 = e^(r)
ln 2 = ln (e^r)
.693 = r•(ln e), ln e = 1, so r = .693
Now that we have our doubling rate of .693, we can use that r and our t as the 12th hour is t=11, because there are 11 more hours at the end of that first hour
So our initial population is again 15, and P = i•e^rt
P = 15•e^(.693×11) = 15•e^(7.624)
P = 15•2046.94 = 30,704

(a) Count the number of ways to select a sample of 3 people to serve on a board of directors from a population of 6 people______
ValentinkaMS [17]

Answer:

(a) 20 ways

(b) 0.05 or 5%

Step-by-step explanation:

(a) Assuming that the order in which people are chosen does not matter, the number of ways to select 3 people out of possible 6 is given by the following combination.

n=\frac{6!}{(6-3)!3!}=\frac{6*5*4}{3*2*1}=20\ ways

(b) In a random sampling procedure, every outcome is just as likely to occur. Therefore, the chances that any particular sample will be the one selected are:

C = \frac{1}{20}=0.05 = 5\%
