Considering the margin of error, it is found that the 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).
<h3>What is a confidence interval?</h3>
It is given by the sample statistic plus/minus the margin of error.
In this problem, 68% of adults say such vaccines should be required, with a margin of error of 3.1%, hence:
68% - 3.1% = 64.9%.
68% + 3.1% = 71.1%.
The 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).

Answer:
The completely factorized form is: (x - 1)(x + 2 )(x - 3)
Step-by-step explanation:
To find the solution, we use Ruffini's rule:
1 - 2 -5 + 6
We first divide by (x-1): 1 1 -1 -6
________________________
1 -1 -6 0
Then divide by (x + 2): - 2 -2 +6
_______________________
1 -3 0
Then, the rest of the division is: x - 3
Thus, the completely factorized form is: (x - 1) (x + 2 ) ( x - 3)
Step-by-step explanation:
The answer is 70 because each men chops 7 trees so 10 men = 70 trees
Y = yo + Vot - (gt^2)/2
y = 10 + 27t - 16.087t^2 [I used g = 32.174 ft/s^2]
You can find y with the quadratic formula or probe with the different times given.
I tried with t = 2 s and found
y = 10 + 27(2) - 16.087 (4) = 10 + 54 - 64.348 = -0.348
Then that is the answer, t = 2s.
