Answer:
-2
Step-by-step explanation:
Start on -5 on the left side of the number line, jump from -5 three times to the right of the number line since ( - - ) means to add. As you jump draw "bridges" and by the time you have completed the amount of jumps you have to do you'll end up with a difference of -2.
Answer:
the ordered pair will be (1, 2)
Step-by-step explanation:
first of all substitute the x and y values into the equation in other to make the equation true.
Therefore y=4x-7
1 = 4(2) -7
1 = 8 -7
1 = 1
Making the first equation true. then move to the second equation which is y = - x + 3
1 = -(2) + 3
1 = 1

Answer:
a. Identify the population of interest in this study.
- all the population of the country
b. Identify the sample for the study.
- 50 adults (the ones that were surveyed)
c. Identify the parameter of interest in the study.
- the parameter of interest is the people that believe that coffee shops are overpriced
d. Find and interpret a 95% confidence interval for the parameter of interest.
z score for a 95% confidence level = 1.96
margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579
95% confidence level interval:
0.4 - 0.13579 = 0.26421
0.4 + 0.13579 = 0.53579
- 95% confidence interval (0.26421 , 0.53579)
