Francisco purchased x hot dogs and y hamburgers at a baseball game. he spent a total of $10. the equation below describes the relationship between the number of hot dogs and the number of hamburgers purchased.

3x + 4y = 10

the ordered pair (2, 1) is a solution of the equation. what does the solution (2, 1) represent?
select one:
hot dogs cost $2 each and hamburgers cost $1 each.
francisco spent $2 on hot dogs and $1 on hamburgers.
francisco purchased 2 hot dogs and 1 hamburger.
hamburgers cost 2 times as much as hot dogs.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

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

0.85% : )
