A 15-kg ball is tossed up into the air. The ball is 2 meters off the ground traveling 4
m/s.
What is the potential energy?
294 J
120 J
414 J
0

Step-by-step explanation:

potential energy =mass*gravity*height

=15*9.8*2

= 294 j

is should be y = 5x

step-by-step explanation:

correct me if im wrong

85.560%

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
