Add three more negative tiles remove the zero pairs add three more positive tiles
remove three positive tiles
–15) + 4 + (–7) = (–7) + (–15) + (–4)
(–15) + 4 + (–7) = 7 + 15 + (–4)
(–15) + 4 + (–7) = 4 + (–15) + (–7)
(–15) + 4 + (–7) = 4 + 15 + 7

step-by-step explanation:

how many centimeters did the level of the salsa go down by?

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

i believe the answer is 323 ft
