If y = 8x-2, which of the following sets represents possible inputs and outputs of the function, represented as
ordered pairs?
o{(0, -2), (1, 6), (2, 14)
o {(0, -2), (2, 13), (-5, -40)}
o {(1,7), (2, 7), (3, 7)}
o {(1,6), (2, 13), (3, 24)}

Step-by-step explanation:

The given equation is

Notice that this equation represents a linear graph, because it's a linear equation.

Now, to know which pair belongs to this equation, we just need to evaluate them.

For

For

For

Therefore, the first set belongs to the fiven equation, so the answer is the first choice.

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
