Answer pls

The last one  

Step-by-step explanation:

It would be the last option because the arrows point towards the right, and whenever the circle if filled (the dot), it means it's equal

x≥-53 (x is greater than or equal to -53)

Step-by-step explanation:

First thing to notice is the point on your graph, is it open or closed. Closed like in this case means a ≤ or ≥ symbol is present so you can rule out any of the ones that don't have the equal to sign. Next where is the sign pointing to, in this case x is greater than and so our sign is pointing to the right which matches up with the line on the graph.

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
