Answer:
Step-by-step explanation:
7-x=10
subtract -7 from both sides
-x=10-7
-x=3
x=-3
Answer:
| x-3| >1:
x>4 or x<2
| 2x+5 | >0.5
:
x > −2.25 or x < −2.75
| 0.2x+3.5 | > 1.7:
x > −9 or x < −26
| x+3 | <1:
x < −2 and x > −4
| 2x+5 | <0.5
x < −2.25 and x > −2.75
| 0.2x+6 | <0.15
x < −29.25 and x > −30.75
| x+5 | >-1
x > −6 or x < −4
| 2x+3 | <-1
No solutions.
| 0.7x +5 | >6.7
x>2.428571 or x<−16.714286

Answer:
The 99% confidence interval for the population proportion of employed individuals who work at home at least once per week is between (0.104, 0.224).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 99% confidence interval for the population proportion of employed individuals who work at home at least once per week is between (0.104, 0.224).
