The graph of f (x) = rootindex 3 startroot x + 8 endroot is shown.

on a coordinate plane, a cube root function goes through (negative 16, negative 2), has an inflectio point at (negative 8, 0), and goes through (0, 2).

which statement is true?

the function is only increasing when x ≥ −8.
the function is only increasing when x ≥ 0.
the function is always decreasing.
the function is always increasing.

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

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
