If y=27x+405,what does x equal ? a=(y-27)405b=(y-405)27c=y-432d=y/27 -405write how to solve the equations?

The value of the equation for x is .

Step-by-step explanation:

Consider the provided equation.

We need to solve the equation for x.

Subtract 405 from both sides

Simplify the equation.

Divide both sides by 27.

Hence, the value of the equation for x is .

if x decreases by 4 then y increases by 10

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
