Cost = (3500 W)·(1 kw/1000 W)·(10 hrs/day)·(30 day/month)·($0.13/kw-hr)
Cost = (3500·1·10·30·0.13 / 1000)·(W·kW·hr·da·$ / W·da·month·kw·hr)
Cost = <em> 136.50 $/month</em>
(1,4) you go right 1 time, and than go up 4.
The slope of the line is 1/3
Answer:
B. <em>There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>
Step-by-step explanation:
A. <em>One has 90% confidence that the sample proportion is equal to the population proportion. </em>
Confidence interval gives an interval estimate, not an equality
B. <em>There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>
<em>Ture. </em>
<em>C.</em><em> One has 90% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion. </em>
Also true but <em>One has 90% confidence is not good interpretation. </em>
<em>D</em><em>. 90% of sample proportions will fall between the lower bound and the upper bound.</em>
<em>Lower bound and upper bound is given to estimate population proportion. </em>
Answer:
The area of the figure is 28 units².
Step-by-step explanation:
Find the area of the full rectangle, ignoring the triangle.
![a = lw \\ a = 4 \times 8 = 32](https://tex.z-dn.net/?f=a%20%3D%20lw%20%5C%5C%20a%20%3D%204%20%5Ctimes%208%20%3D%2032)
Then, find the area of the triangle:
![a = \frac{bh}{2} \\ a = \frac{2 \times 4}{2} \\ a = 4](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bbh%7D%7B2%7D%20%20%5C%5C%20a%20%3D%20%20%5Cfrac%7B2%20%5Ctimes%204%7D%7B2%7D%20%20%5C%5C%20a%20%3D%204)
Finally, subtract:
![32 - 4 = 28](https://tex.z-dn.net/?f=32%20-%204%20%3D%2028)
