4x + 3 (5x + 6) = -3x - 10

show all steps i need this

x=-2

Step-by-step explanation:

Expand

-4x+15x+18=-3x-10

Simplify

11x+18=-3x-10

Add 3x to both sides

11x+18+3x=-10

Simplify

14x+18=-10

Subtract 18 to both sides

14x=-10-18

Simplify

14x=-28

Divide both sides by 14

x=-28/-14

Simplify 28/14 into 2

x=-2

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
