Identify the variation as direct, inverse, joint or combined.
v = cw
a) direct
b) inverse
c) joint
d) combined

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or

In this problem we have

Let

v-----> the dependent variable

w-----> the independent variable

c-----> the constant of proportionality

therefore

-----> is a linear equation that represent a direct variation

the answer is the option A

Direct

step-by-step explanation:

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
