Plz I need help
pls give me an explanation along with the answer

176

Step-by-step explanation:

okay, so we will use 55 and 176.

lets create an equation!

55 x + = 176

we can switch 176 over to the other side and y to the other side.

55x + 176 = y

now we use the substitution method to answer this:

we substitute y with the equation above!

55x + 55x +176 = 176

110x + 176 = 176

110x = 0

x = 0

now we substitute x into the original equation to find y:

55 x 0 + y = 176

y = 176

Okay so x + y

= 0 + 176 =

176

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
