Answer:
a) true
Step-by-step explanation:
There are 13 heart-suit cards in a 52 card deck.
Since cards are returned to the deck after each pick, all of the 15 events are independent and have the same likelihood of occurring. Therefore, this experiment follows a binomial distribution with the following properties:
Number of events (n) = 15
Probability of success (Picking a heart) = 13/52 = 1/4
Probability of failure (Not picking a heart) = 39/52 = 3/4
In conclusion, the statement provided is true.

Answer:
in day 44 it covered half the area.
Step-by-step explanation:
A bacterial culture doubles every two days, so if today it covers
, in two days it will cover
. In other words, if today it covered x space, two days ago it covered half the space
.
Now, following that reasoning, we have that after 46 days the bacterial culture covered the entire surface area in the Petri dish, therefore, two days ago it covered half the area and we can conclude that in day 44 it covered half the area.
