Use properties to determine whether the expressions are equivalent.
3(5 − 2x) and 3(2x) − 3(5)

Hello!

Yes, they are equivalent.

Step-by-step explanation:

Expression 1: 3(5-2x) = 15-6x

Expression 2: 3(2x) − 3(5) = 6x-15

Expression 1 and 2 have the same solution set. Which means they are equivalent.

Hope this helps!

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
