This hanger is in balance. there are 2 labeled weights of 4 grams and 12 grams the 3 circles have the same weight. what is the weight of each circle.

8/3

Step-by-step explanation:

3x+4=12

find what x equals

subtract 4 on both sides (+4-4=0) (12+4=16)

then we have 3x=16

divide 16 by 3 = 8/3 (simplest form)

check-       3(8/3) + 4=12

                    ^=8+4=12

                          ^=12=12    so the answer is 8/3    i hoped this helped!

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
