Since each min is 60 seconds you multiply 60 by the number of minutes which is 7 and you get 420:
60x7=420 Then you add 30 seconds equaling 450 seconds total
Then you divide 450 by 4 since she ran 4 laps.
So, Stephanie ran 112.5 seconds per lap
Answer:
That would be a fairly weak positive correlation.

Add 3/16 to both sides to isolate the variable on one side. Then the equation should be x=8/16 which is 0.5.
Answer:
The answer to your question is below
Step-by-step explanation:
a) Fill in the table
Time (weeks) 0 1 2 3
Plant height (ft) 0 3.5 7 10.5
c) The moment when the seed is planted.
d) speed of growth
e) P(t) = 7/2 t
P = height
t = time in weeks
f) P(9) = 7/2 (9) = 63/2 = 31.5 ft
g) 35 = 7/2t
70 = 7t
t = 70 / 7
t = 10 weeks
