Answer:
1.) The number of teachers who use Google Meet only is 18.
2.) The number of teachers who use Zoom only is 20.
3.) The number of teachers who use both Google Meet and Zoom is not mentioned explicitly in the given information, so we cannot determine this value.
4.) To find the number of teachers who did not use either Google Meet or Zoom, we need to subtract the total number of teachers who use either Google Meet or Zoom from the total number of teachers surveyed (which is 30).
Step-by-step explanation:
Let's calculate the number of teachers who did not use either Google Meet or Zoom:
Total number of teachers surveyed = 30
Number of teachers who use Google Meet = 18
Number of teachers who use Zoom = 20
Number of teachers who did not use either Google Meet or Zoom = Total - (Google Meet + Zoom)
= 30 - (18 + 20)
= 30 - 38
= -8
2. 20 of them uses zoom
3. 38 teachers in total uses google meet and zoom
4. 8 of them did not use any of two
