Ascientist planted 120 seeds, and 90 sprouted. what percent of the seeds failed to sprout?

Do 120 seeds - 90 that have sprouted.

120-90= 30

30 divide by the total number of planted 120 seeds

30/120= 1/4

1/4 times 100 to get the percent

1/4*100

Cross out 4 and 100 , divide by 4 . 4/4= 1

100/4= 25

1/4=25 %

25%

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
