Answer:
D. We can be 95% confident that the proportion of all cell phone users who use text messaging is between 73.1% and 76.9%.
Step-by-step explanation:
The interpretation of a confidence interval of level x% means that we are x% sure that the interval contains the true mean of the population.
In this problem, we have that:
The population are all the cell phone users.
The 95% confidence interval is (73.1%, 76.9%).
Which of the following is an appropriate interpretation of the 95% confidence interval?
D. We can be 95% confident that the proportion of all cell phone users who use text messaging is between 73.1% and 76.9%.
Option 1: 
is the correct answer
Step-by-step explanation:
We can put the values of x in each option one by one and then compare the output to find the best option
So,
<u>For y = 5x+5:</u>
Putting x=1,2,3,4,5...
The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5
Hence,
Option 1: is the correct answer

Answer: Graph (0,10) and (3,9).
Step-by-step explanation: The equation is written in slope-intercept form (y=mx+b). b represents the y-intercept.
So you would graph (0,10) on the graph.
To find the other points, you can use the triangle method for finding slope. -1/3x is the slope. -1 means you go down by one space on the y line. 3 means you go right by 3 spaces on the x line. This leads you to the point (3,9). You can use this method to find the other points on the graph.
