Answer:
The lower confidence limit of the 95% confidence interval for the population proportion of Americans who were victims of identity theft is 0.0275.
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 z-score that has a p-value of .
A 2003 survey showed that 14 out of 250 Americans surveyed had suffered some kind of identity theft in the past 12 months.
This means that
95% confidence level
So , z is the value of Z that has a p-value of , so .
The lower limit of this interval is:
The lower confidence limit of the 95% confidence interval for the population proportion of Americans who were victims of identity theft is 0.0275.
The answer to your question is y=<span><span>−x</span>−<span>1</span></span>
X=8 because you have to simplify both sides, thats the only way it could be a one step equation, your welcome
The three terms are 3d/4 and -1/2 and 7. Multiply each of these terms by 4. Why 4? This is the lowest common denominator (LCD) of the fractions. If we multiply all the terms by the LCD, then the denominators will cancel out. This will get rid of the fractions.
4 times 3d/4 = 3d
4 times -1/2 = -2
4 times 7 = 28
After multiplying each term by 4, we end up with the equation 3d - 2 = 28
Let's solve for d
------------------------
3d - 2 = 28
3d-2 + 2 = 28+2 .... add 2 to both sides
3d = 30
3d/3 = 30/3 .... divide both sides by 3
d = 10
------------------------
The final answer is d = 10
