Answer:
<em>It will take 26.34 minutes for the population to reach 5 times its initial value</em>
Step-by-step explanation:
<u>Exponential Growing</u>
The population of bacteria grows at a rate expressed by the equation:
Where t is in minutes.
We need to know when the population will reach 5 times its initial value. The initial value can be determined by setting t=0:
Now we find the time when the population is 5*256=1,280. The equation to solve is:
Dividing by 256:
Taking natural logarithms:
Applying the logarithm properties:
Solving for t:
It will take 26.34 minutes for the population to reach 5 times its initial value
Question:
The majority of U.S. car owners still buy American cars." Ideally, what would the sample be in the study that generated this stat?
answer choices
a) Everyone in the United States who owns a car
b) Everyone in the United States who owns an American car
c) A randomly selected group of car owners in the U.S.
d) A randomly selected group of Americans who own American cars
Answer:
A randomly selected group of car owners in the U.S.
Step-by-step explanation:
In this study, we are told the majority of U.S car owners still buy American cars. The sample in the study that generated this stat would be "a randomly selected group of car owners in the U.S".
⬤ Option A is incorrect, because collecting a sample from every car owner in U.S is impossible as the sample size would be rather tool large.
⬤ Option B is also incorrect because just like in option A, the sample size would be too large. Also this does not take into consideration those who don't use American cars
⬤ Option D is incorrect, this study deals with all car owners in the U.S, not Americans who own American cars. Therefore selecting a sample from Americans who own American cars would be wrong.
Answer:
A radical function contains a radical expression with the independent variable (usually x) in the radian. Usually radical equations where the radical is a square root is called square root functions. An example of a radical function would be. y=√x. This is the parent square root function and its graph looks like.
Step-by-step explanation:
Answer:
The answer is undefined because it has a denominator of 0.
Step-by-step explanation:
When finding slope using two points, use the format y-y1/x-x1. First, plug in both of your points to get this: -6--6/-8--8. -6--6 equals 0, and -8--8 equals 0. So, your slope would be 0/0. Because your slope has a denominator of 0, the answer would be undefined. Hope this helped and let me know if you have questions!
