Answer:
B. There is 85% confidence that the proportion of the adult citizens of the nation that dreaded Valentine's Day is between 0.227 and 0.273
Step-by-step explanation:
The confidence level means the confidence that we have that the true mean is in the interval calculated.
The margin of error represents the range of values below and above the sample statistic in a confidence interval. For example, if the sample statistic is 25% with a margin of error or 2.3%, the interval is between 25-2.3 = 22.7% and 25 + 2.3 = 27.3%.
So the correct answer is:
B. There is 85% confidence that the proportion of the adult citizens of the nation that dreaded Valentine's Day is between 0.227 and 0.273
Answer:
see below
Step-by-step explanation:
y = x^2 - 6x + 14 'complete the square for 'x'
x^2 - 6x + 9 - 9 + 14
y = (x-3)^2 + 5 vertex from <u> vertex = (3,5) </u>
since the coefficient of ^2 is positive it is a bowl shaped parabola and the vertex is a <u>MINUMUM</u>
vertex
answer: 35%
Step-by-step explanation: 1/4 is 25 so add 25 and 40, you get 65. Subtract 65 by 100 and u get 35. Therefor, 35% is your answer! plz mark brainliest or rate :D
It’s literally it except it’s the other way around so it’s: -35, -18, -10, 5, 15
