Answer: t = 1.9287
Step-by-step explanation:
Let be the average number of pages should be sent by 2-day mail instead.
As per given we have,
Sample mean :
Sample standard deviation : s=3.81
sample size : n= 24
Since , the sample size is less than 30 and populations standard deviation is unknown , so we use t-test.
The test statistic for population mean :-
Hence, the test statistics : t = 1.9287
I think It should be "Variable".
225,113 rounded to the nearest hundred thousand is 300,000
Answer:
Step-by-step explanation:
Common ratio r = a₂/a₁ = -9/27 = -⅓
b(1) = 27
b(n) = b(1)rⁿ⁻¹ = 27(-⅓)ⁿ⁻¹
Answer: Option B.
Step-by-step explanation:
The equation of the line in Slope-intercerpt form is:
Where "m" is the slope of the line and "b" is the intersection of the line with the y-axis.
For the graph of the line , you can identify that:
And for , you can identify that:
Therefore, you can observe that the slope does not change, but now the line cuts the y-axis at . In other words, it was moved from to (3 units on the y-axis)
Then, it is the graph of translated 3 units upward, which means that the graph of g(x) is 3 units above the graph of f(x).
