What is the range of the given function? you

Option B: {y | y = -7, -1, 0, 9}

Step-by-step explanation:

The range of a function is the set containing the all the values of the y-coordinates of the points of the function.

This function's points have the y-coordinates: 9, 0, -7, -1

The range is: {-7, -1, 0, 9}

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
