Answer:
The mean is 21.12.
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
![E(X) = np](https://tex.z-dn.net/?f=E%28X%29%20%3D%20np)
In this question:
![n = 48, p = 0.44](https://tex.z-dn.net/?f=n%20%3D%2048%2C%20p%20%3D%200.44)
Mean:
![E(X) = np = 48(0.44) = 21.12](https://tex.z-dn.net/?f=E%28X%29%20%3D%20np%20%3D%2048%280.44%29%20%3D%2021.12)
The mean is 21.12.
Answer:
Patient A - 150 mg
Patient B - 50 mg
Step-by-step explanation:
Since patient A gets three times more, 50 times 3 is 150. 150 plus 50 is 200, therefore, patient A gets 150 mg and patient B gets 50 mg. I hope this helps :)

So we need to find the length of the hypotenuse of a right triangle with sides of 3 and 4, then add that distance to 3 and 4.
By the Pythagorean Theorme, the hypotenuse squared is equal to the sum of the sides squared...
d^2=3^2+4^2
d^2=9+16
d^2=25
d=√25
d=5
So the total distance of her run is 5+4+3=12 km
