When in doubt, graph it.
The 3rd and 4th choices are appropriate.
_____
This is what is known as a "logistic function." It is used to model population growth when there is a resource limit. It starts out exponential, but then slows as it reaches the "carrying capacity" of the environment. The lower asymptote is zero; the upper one is the carrying capacity of the resource--here 15/1 = 15.
Answer:
37
Step-by-step explanation:
Here, we have two different samples, hence, to obtain the confidence interval, we use the relation for the confidence interval for two sample means ;
(x1 - x2) ± Margin of error
Where, (x1 - x2) = point estimate of the sample mean, this is the difference in mean of the two samples.
From the question ;
x1 = 1150 ; x2 = 1113
Hence, the point estimate is : (1150 - 1113) = 37
Answer:
-2/3
Step-by-step explanation:
Answer:
1. 125,000
3 17.5
4. 15
5. 17.5
Step-by-step explanation:
1. Create a unit rate. 20,000/8 = 2,500 straws per hour. This means in 50 hours multiply 2500*50 = 125,000.
3. Mean is the average and is found by adding all the date points and dividing by the number of them.
15 + 16 + 17 + 23 + 1 1+ 19 + 20 + 15 + 18 + 22 + 15 + 19 = 210
210 / 12 = 17.5
4. The mode is the number that occurs most often. Write the numbers in order and choose the one that happens the most.
11, 15, 15, 15, 16, 17, 18, 19, 19, 20, 22, 23
15 is the mode
5. The median is the number in the middle. If two numbers then take the average. The numbers in the middle when written in order are 17 and 18. So the 17+18 / 2= 17.5
