Answer:
The significance level for this case would be 
and the critical value for this case would be:
The margin of error is given by:
And replacing we got:
And the margin of error for this case would be 
Step-by-step explanation:
For this case we have the following dataset given:
represent the sample size
represent the estimated proportion of interest
represent the confidence level
The significance level for this case would be and the critical value for this case would be:
The margin of error is given by:
And replacing we got:
And the margin of error for this case would be
12.9/ .6= is 21.5 hope this is what you need!!:)
Answer:
Step-by-step explanation:
I'm never sure how far to go on these questions but I think what I'e done looks pretty nice. Essentially I simplified each radical, factored out each variable, combined the radicals after more simplification, and then picked the answer you were most likely looking for. I gave some alternatives in my work that are "simple" too, but the answer above is most likely I'd say.
Work is in the attachment, comment with any questions.
Answer:
George Washington.
Step-by-step explanation:
President Washington was elected President by a unanimous election of 69 voters in 1788, and served two terms. He set about creating a strong, well-funded national government that would maintain neutrality in Europe's raging wars, quell uprisings, and gain the approval of Americans of all types. His leadership style has established many forms and rituals of government that have been used, such as the use of a cabinet system and the swearing-in of oaths. Still, the peaceful transition from his presidency to the presidency of John Adams has created a tradition that continues into the 21st century. Washington was hailed as a patriarch, even during his lifetime.
Answer:
Domain= {
}
Step-by-step explanation:
The function given is: 
, and we are asked to find the Domain of it. Let's recall that the Domain of a function is the set of all x-values for which the function is defined (can be evaluated rendering a real number as result). So in order to find which x-values constitute such Domain, let's investigate for which x-values we can effectively evaluate the square root of "x+6".
Notice that the square root is not defined for radicands that are negative (less than zero). The only radicands that are allowed are those greater than or equal to zero. So that is exactly the condition we want to impose on the radicand: to be greater than or equal to zero (
). Our radicand is the expression: "x+6", so we write in math terms the necessary condition as:
and solve for "x" in the inequality (isolating "x" on one side:
The Domain of this function is therefore all those real "x" values that are greater than or equal to negative 6 ()
