I dont have an answer buy i need to answer a question so i can ask my question sry
Ok so if 1200 total pens and 60 were taken that's a ratio of 1200/60=20
out of 60pens 4 didn't work, again ratio is 4/60=1/15 so about 1/15 of the pens didn't work.
so we have 1200pens * 1/15broken ratio = 80 pens or we can say
20*4=80pens won't work from 20 groups of 60 and 4 out of 60 not working is 20*4=80 not working from total batch of 1200.
hope this helps you some! thank you!!!!!!!!!
I need the equation to be able to help
Answer:
Its the alternative C because as you can see the dots ar placed in the following coordinates(sorry for my English). The first dot is placed (1, 4) the second is placed (2, 6) the third is (3, 10) and last is (4, 12)
You have to put the number under 1 so you would get 1 over -27
