Set. A survey was carried among 160 schools in which 70 have a library, 50 have a computer lab, 20 have computer lab and science lab, 15 have library and science lab, 10 have all three labs. Represent the above information in a venn diagram. Also find,
1. How may schools have none of these facilities.
2. How many schools have only one lab?
3. How many schools have only two labs?
4. How many schools do not have a computer lab?

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

what's the question here?

the ratio would be 4: 3, the four being for jackson, and the three being not for him.
