Answer:
(a) 36.36%
(b) 0.36%
(c) 0.06%
Step-by-step explanation:
Given that the time intervals measured with a stopwatch have an uncertainty of about 0.2 s.
We want to know what is the percent uncertainty of a hand-timed measurement of:
(a) 5.5 s
Percentage = (0.2/5.5) × 100
≈ 36.36%
 (b) 55 s
Percentage = (0.2/55)×100
≈ 0.36%
(c) 5.5 min
5.5 min = 5.5 × 60 s
= 330 s
Percentage = (0.2/330)×100
≈ 0.06%

hi hun!
From what I understand, ill explain to the best of my knowledge so u understand!
First. off they asked for "proportionality" basically asking for the rate it's growing at or weeks its taking.
I see that:
Flower 1: 6 inches
Flower 2: 10 inches
Flower 3: 14 inches
The proportionality which these flowers are growing at is 4 inches every two weeks.
And I also see:
Week 3
Week 5
Week 7
When u look closer u can see that the weeks are divisible by the inches for each of the flowers and each answer u get is 2!
And also just by looking at the weeks which are 2 weeks separate if u count them. 
Week 3 would be:
6/3=2
Week 5 would be:
10/5=2
Week 7 would be:
14/7=2
so the proportionality is 2! c:
