Step-by-step explanation:
(3000N) F–D = m a2. D= F–m a2. = 3000N– 1200kg × 0.75 m s-z.
Answer:
I dont really understand the question but I think its -7.
Answer:
Well this is a bit of a tall order :) but here we go:
A. See the attached frequency tables, done vertically and horizontally.
B. We can see from the horizontal freq table that .6 = 60% of all the pine trees died.
C. The probability that a tree survived given it was a pine is .6 = 60%. The probability that a tree survived given it was an oak is .75 = 75%. According to this sample, the oaks were more likely survive than the pines.
