Answer:
Step-by-step explanation:
Given that the random variable x represents the number of phone calls an author receives in a day
Poisson distribution is a discrete distribution with random variable countable.
Here no of calls cannot be in fraction or decimal.
Also given that X is Poisson with mean = 7.6
X is discrete since no of phone calls can take values as 1,2,3....
X can take any value from 0 to infinity.
x=3.2 is not possible since 3.2 calls does not exist.

Answer:
Ari catches up to Amanda at 19.3 meters
Step-by-step explanation:
Given :
Ari is swimming a 25-meter race.
After swimming 6 meters she catches up to Amanda in a ratio of 7:3 from the 6-meter mark.
Solution :
The distance between 6 meters and 25 meters = 19 meters.
Since she catched Amanda in ratio 7:3
So, she catched her at 7/10 of the distance
So, the distance at which she catched Amanda =
=13.3
Ari catches 13.3 metres from 6 m marks
The point on number line at which she catches her = 13.3+6
Hence Ari catches up to Amanda at 19.3 meters
108=103e^(5k)
108/103=e^(5k) take the natural log of both sides
ln(108/103)=5k
k=ln(108/103)/5
k≈0.00948
P=103e^(12*0.00948)
P≈115 million (to nearest million)
