Elena completed the 100-meter run in 15.58 seconds. a. How much faster would she have had to run to tie the record?
b. If she could have run 400 meters at the same rate as she ran 100
meters, would she have broken the record? Find the difference
between her time for 400 meters and the record time.
c. The 400-meter run consists of four laps around a 100-meter track.
What was the record holder’s average time per lap?

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
