A scientist wants to collect data about the effects of gravity on the growth of soybeans. To test her hypothesis that soybeans grow better in a zero-gravity setting, she separates the soybeans into two groups. The first group is grown in typical soybean growing conditions in a greenhouse on earth, and the second group is grown in a zero-gravity, yet otherwise identical greenhouse in a space station. Which of the following is the best description of the research design for this study?

c is the correct answer

step-by-step explanation:

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

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
