The statement that must be true for the given condition is <span>m∠X + m∠Y < 90°</span>
<h3>The domain is all real numbers.</h3>
<h3>On the coordinate plane, the parabola opens down, passes through (-2,0), has a vertex at (0.5,6.75) and goes through (1,0)</h3>
<h3>The vertex is its maximum value.</h3>
Answer:
And the 95% confidence interval would be given (0.419;0.481). And the best option would be:
b. .419 to .481
Step-by-step explanation:
We know the following info:
sample size selected
represent the number of people who favored Candidate AT
The sample proportion would be:
![\hat p=\frac{450}{1000}=0.45](https://tex.z-dn.net/?f=%5Chat%20p%3D%5Cfrac%7B450%7D%7B1000%7D%3D0.45)
The confidence interval would be given by this formula
For the 95% confidence interval the value of
and
, with that value we can find the quantile required for the interval in the normal standard distribution.
And replacing into the confidence interval formula we got:
And the 95% confidence interval would be given (0.419;0.481). And the best option would be:
b. .419 to .481
V=1156 in³
you can find the volume by multiplying the length times width times height
