Jordan shoots a basketball and the ball follows the parabolic path that can be modeled by $$ (height is in feet and time is in seconds). Jordan shoots an air ball (which means he doesn't hit anything and the ball's path doesn't change), at what time will the ball hit the court?

About 0.75 seconds

About 0 seconds

About 1.7 seconds

About 15 seconds

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
