Answer:
Heart sounds
Step-by-step explanation:
- Your doctor has allergic reaction, febrile rash, and meningitis in their differential for the patient.
- In a healthy adult, the heart makes two sounds, commonly described as 'lub' and 'dub. ' The third and fourth sounds may be heard in some healthy people, but can indicate impairment of the heart function. S1 and S2 are high-pitched and S3 and S4 are low-pitched sounds.
Answer:
A:B:C = 5:5:7 or 5x : 5x : 7x
Cindy ate 30 Skittles less than Ann and Ben together
-----> 7x = 5x + 5x - 30
-3x = -30
x = 10
5x = 50
7x = 70
They ate 50+50+70 = 170 of them

Answer:
a) P(x=3)=0.089
b) P(x≥3)=0.938
c) 1.5 arrivals
Step-by-step explanation:
Let t be the time (in hours), then random variable X is the number of people arriving for treatment at an emergency room.
The variable X is modeled by a Poisson process with a rate parameter of λ=6.
The probability of exactly k arrivals in a particular hour can be written as:
a) The probability that exactly 3 arrivals occur during a particular hour is:
b) The probability that <em>at least</em> 3 people arrive during a particular hour is:
c) In this case, t=0.25, so we recalculate the parameter as:
The expected value for a Poisson distribution is equal to its parameter λ, so in this case we expect 1.5 arrivals in a period of 15 minutes.
