On tuesday the value of stock decreased by 1/2 point. on wednesday, the value increased by 3/4 point. on thursday the value decreased by 3/8 point. what integer represents the change in stock value after three days?

can you show your work?

(4x+3)/8

Step-by-step explanation:

Lets assume the integer for value of stock originally = x

On Tuesday, it was decreased by 1/2 , x-1/2 =1/2x

On wednesday, the value inceased by 3/4=1/2x + 3/4= (2x+3)/4

Thursday the value decreased by 3/8 ,= (2x+3)/4 -3/8 =(4x+3)/8

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

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
