Answer:
Total number of edges for resulting solid = 12
Step-by-step explanation:
A wooden block measures 2 inches by 2 inches by 3 inches. A wedge is cut off from each corner of the block by slicing at points that are 1 inch from each corner.
We have to find the number of edges in the resulting solid after we cut the edges as told above.
There are two faces along the height which will become sharpened after we take out the cuts.
So the resulting shape would be like that of a cylinder with its both ends pointed.
So total number of edges = 4 + 4 + 4 = 12
Twice the area of the triangles, triple that of the rectangles.
2t * 3r = a
Answer:
And for the deviation we have:
And that value represent the best estimator for the population deviation since:
Step-by-step explanation:
For this case we have the following data:
1.48,1.45,1.54,1.52,1.52
The first step for this cae is find the sample mean with the following formula:
And replacing we got:
And now we can calculate the sample variance with the following formula:
And replacing we got:
And for the deviation we have:
And that value represent the best estimator for the population deviation since:
Answer:
0.7
Step-by-step explanation:
67/10 is the same as 6.7 when you subtract the 0.7 you will remain with 6
