If 21% of the customers in a restaurant order fish, what is the probability that the next 3 costumers in a row will order fish?

1 answer:

6 0

Probability of ordering a fish=21%=0.21, given that this is an independent event
then the probability of the next 3 customers in a row will order fish will be given by:
P(fish)=0.21×0.21×0.21=0.009261

Answer: 0.009261

If your heart beats 80 times per minute and you live to be 90 years old, estimate the number of times your heart beats during yo

umka2103 [35]

The heart beat is given in units of beats per minute, therefore before we can do any calculations let us make sure that all units are similar by converting the age in terms of minutes.

We know that there are 365 days per year, therefore:

90 years (365 days / year) = 32,850 days

We know that in a day, there are 24 hours, therefore:

32,850 days (24 hours / day) = 788,400 hours

And in an hour, there are 60 minutes, therefore:

788,400 hours (60 minutes / hour) = 47,304,000 minutes

Now calculating for the total heart beats in a lifetime:

total heartbeats = (80 beats / minute) * 47,304,000 minutes

total heartbeats = 3,784,320,000

Writing this into scientific notation:

3.78 x 10^9 beats
