<u>Confidence interval for population proportion is </u>
<u>sample proportion +/- confidence coefficient*standard error of p </u>
<u>Sample proportion = p = x/n = 180/300 = 0.6 </u>
<u>Confidence coefficient is the critical value of z for 95% confidence level = 1.96 </u>
<u>Standard error of p = sqrt [p*(1-p)/n] </u>
<u>= sqrt [0.6*0.4/300] </u>
<u>= 0.0283 </u>
<u>The CI is </u>
<u>0.6 +/- 1.96*0.0283 </u>
<u>0.6 +/- 0.055 </u>
<u>lower boundary is 0.6-0.055 = 0.545 </u>
<u>upper boundary is 0.6+0.055 = 0.655 </u>
<u>The CI is (0.545, 0.655)</u>
$3.50 because it’s simple all you got to do is divide both sides
<h3>
<u>Explanation</u></h3>
A linear function has an equation of y = mx+b where m = slope and b = y-intercept. The function also has a line graph. By a line graph, the graph must have slope. That means the slope must not equal to 0 or undefined to be a linear function.
<u>Further</u><u> </u><u>Explanation</u>
A linear function has both domain and range as set of all real numbers because you are able to solve for x-term when inputting any y-value or solve for y-term when inputting any x-value. We can also find the x-intercept by substituting the value of y to 0 and basically solve for x-term. If we want to know the y-intercept, we can substitute x-term to 0 and solve for y. But most people would only look at b-term from y = mx+b because b-term is the y-intercept of function.
<h3>
<u>Answer</u></h3>
From your question, the function is indeed a linear function. The m-term and b-term both are from y = mx+b where m = slope and b = y-intercept.
Therefore, from y=6x+2. The m-value would be 6 and b-value would be 2
Answer: There would be 17 Left-handed students
Step-by-step explanation: I know there's a common core way to do this by doing cross multiplication with 1/5 x "x"/85 (x being the answer) but this question is simple enough to just divide 85 by 5
Yo subtract 5- 2.75 and you get 2.25. 2.25 divided by .375 is 6 so 6 deli sandwiches were made
