Answer:
Company X - 190 students
Company Y - 114 students
No phones - 76 students
Step-by-step explanation:
1) Find a multiplier to get the ratio from sample to population; to compare the sample to the population
380/120 = 3.16666667 or 3 & 1/6
380 comes from the total population of students and 120 comes from the randomly selected.
2) Use our multiplier to compare the results to the population
<u>People with Company X</u>
<u>People with Company Y </u>
<u>People with no cell phone</u>
- 24 * 3.166667 = 76.0000000001 = 76 (rounded)
<u>Double check</u>
190 + 114 + 76 = 380

Assuming the cube is closed, you can use the divergence theorem:
where is the surface of the cube and is the region bounded by .
We have
so the flux is 0.
A is 2 and B is 24 bc 12/6 =2 and 6x4=24
