V(t) = 32t
when t = 3 seconds,
V = 32*3
V = 96
So velocity will be 96 units/s after 3 seconds.
Answer:
x=29
y=69
i might be wrong but i think im correct
Answer: If P(x<a) = 0.6, then the value of a will be 0.25.
In this type of problem, it is safe to assume the normal distribution unless you are told something different.
In this probability, we have to find the z-score for a that gives a probability of 0.6. You will need a normal distribution chart to do this problem. Just find the probability that is closest to 0.6 and use that z-score.
The sum evaluates to 144. See the linked question in the comments for details.
By using the equation y-y1=m (x-x1) you can plug in your coordinates(2 into y1,-4into x1) and your slope (9/2 in for m) you get your equation y-2=9/2 (x+4) this is the equation of a line that has a slope of 9/22nd and passes through the point (-4,2)
