At a track meet with 200 participants, 45 participate in jumping event, 1/3 of these jumpers are female, and 1/2 of the the total participants are female. What is the probability that a participant chosen at random is a jumper, given that the person is a female?

The correct answer is 0.15.

Step-by-step explanation:

Total number of participants for the track meet = 200

Number of females among the participants = × 200 = 100

Number of persons participate in the jumping event = 45

Number of females among these jumper = × 45 = 15

Therefore the number of female jumpers are 15 out of the 100 female participants for the track meet.

Therefore the probability that a participant chosen at random is a jumper, given that the person is a female is = 0.15

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
