Give the domain and range. domain: {2, 0, 2}, range: {1, 0, 1}

1 answer:

5 0

<h2>Domain: {0, 2}</h2><h2>Range: {0, 1, 1}</h2><h2 /><h3>When dealing with the domain, remember that no numbers can repeat in the domain so if there is more than one of the same number, we only list it one.</h3><h3 /><h3>When dealing with the range, it's ok if numbers repeat because it's the y-value not the x-value.</h3><h3 /><h3 />

What happens to the width of a confidence interval for a population mean if the level of confidence is increased without changin

natulia [17]

Answer: If the level of confidence is increased without changing the sample size then<em> </em><u><em>The margin of error will decrease because the critical value will decrease. The decreased margin of error will cause the confidence interval to be narrower.</em></u>

where;

<em>Margin of error = Critical value × Standard deviation</em>

<em>Here, it can be duly noted that Margin of error has a positive relation with critical value, i.e </em><u><em>The margin of error will decrease because the critical value will decrease.</em></u>

<u><em>whereas;</em></u>

The confidence interval is <em>the value ± the margin of error.</em>

<em>Therefore, </em><u><em>the decreased margin of error will cause the confidence interval to be narrower.</em></u>

Cot is an inverse of tan:

${ \tt{4 \cot( \theta) = \tan( \theta) }} \\ { \tt{ \frac{4}{ \tan( \theta) } = \tan( \theta) }} \\ \\ { \tt{4 = { \tan }^{2} \theta }} \\ { \tt{ \tan \theta = ±2}} \\ { \bf{\theta =±63.4 \degree }}$
