Answer:
D)We are 95% confident that the proportion of adults (ages 17‐26) who attended college during the past 4 years and say that alcohol and drug use at their school is a big problem is between 53% and 59%.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
95% confidence interval is (0.53, 0.59).
This means that we are 95% sure that the true proportion for the population of adults who attended college who say that alcohol is a big problem is between 0.53 and 0.59. This means that the answer is given by option D.
Answer:
f(-3)= <em><u>-</u></em><em><u>5</u></em>
g(4)= <em><u>7</u></em>
Step-by-step explanation:
here f(x)= -5, clearly it's not depending on 'x' ,so it will have same value,for all x
i.e, f(-3) is also -5
and, g(x)=2x-1
to get g(4) put x=4 in <u>2</u><u>x</u><u>-</u><u>1</u>
i.e, (2×4)-1 =7
