Answer:
The range of the function will be (- ∞, 4].
Step-by-step explanation:
See the graph attached.
Here we have to get the range of the graphed function.
The value of y in the graphed function varies in the range of less than or equal to 4.
Because the graph of the function does not move beyond 4 towards +∞.
Therefore, the range of the function will be (- ∞, 4]. (Answer)
Answer:
The 99% confidence interval for the true mean number of reproductions per hour for the bacteria is between 9.6 and 10.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 9.8 - 0.2 = 9.6 reproductions per hour.
The upper end of the interval is the sample mean added to M. So it is 9.8 + 0.2 = 10 reproductions per hour.
The 99% confidence interval for the true mean number of reproductions per hour for the bacteria is between 9.6 and 10.
10.9 is closer to 10.
If you add another 0 to the end of 10.9 to make it 10.90, you may realize that it is less than 10.99, which has a 9 in the hundredths place.
Mean = Numbers added up and divided by the amount of numbers.
Mean = 45 + 90 + 18 + 53 + 13 + 38 + 22 + 59 + 49
Mean = 387 ÷ 9
Mean = 43
Median = The middle number when arranged in order
Median = 13, 18, 22, 38, 45, 49, 53, 59, 90
Median = 45
Mode = The number that occurs most often
Mode = There is no mode because each number occurs the same amount of times
Range = Biggest number takeaway smallest number
Range = 90 - 13
Range = 77
