The rate of change is ur slope.
The table : company p
y/x = 0.4/10 = 0.04
the graph : company s
y/x = 6/100 = 0.06
Company s (the graph) has the greatest rate of change
The last one
x^2-3X-28

Answer:
I would say 340 grams........
Step-by-step explanation:
340 grams
Let get all the information.
Mean:394
Deviation:35
Looking for At Least 380 feet
To find the z score you take the wanted probality subtract the mean and divide by the deviation.
z=(380-394)/35.
z=-0.4
So far so good.
But when he looked at the table he looked at probability that the home runs are less then 380 feet.
From this table
http://www.stat.ufl.edu/~athienit/Tables/Ztable.pdf
To find the answer you have to take 1-(the probability that the home runs are less than 380 feet)or 1-0.3446=0.6554
He made an error in his calculation.
