Answer:
The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.
Step-by-step explanation:
Margin of error
In which 
is the standard deviation and n is the size of the sample.
Standard deviation of 1.3
This means that 
She surveys 124 families
This means that 
Margin of error and meaning:
The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.
The graph is labeled on the side(Followers) and on the bottom(Days). With the table, you count the lines to find the point you need to be on. For example, the 1st day Trey got 120 followers. You would find #1 on the bottom part of the graph, and then proceed to find 120 on the side of the graph. Trace towards the middle, and where they meet is where you would place the point.
48 on call = 3.5 hours for 10 dollars = 1/2 hours for 1.5
Answer:
k = -7
Step-by-step explanation:
Find the difference of the y-values of both vertexes:
f(x): y = 1
g(x): y = -6
g(x) - f(x)
-6 - 1 = -7
