Answer: 0.8461
Step-by-step explanation:
Given : 
Let x be the random variable that represents the cost for the hospital emergency room visit.
We assume that cost for the hospital emergency room visit is normally distributed .
z-score for x=1000 ,
![z=\dfrac{1000-1400}{392}\approx-1.02\ \ \ [\because z=\dfrac{x-\mu}{\sigma}]](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B1000-1400%7D%7B392%7D%5Capprox-1.02%5C%20%5C%20%5C%20%5B%5Cbecause%20z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5D)
Using z-value table , we have
P-value =P(x>1000)=P(z>-1.02)=1-P(z≤ -1.02)=1-0.1538642
=0.8461358≈0.8461 [Rounded nearest 4 decimal places]
Hence, the probability that the cost will be more than $1000 = 0.8461
Answer:
The dashed hypotenuse measures: 3,205.13 ft.
Step-by-step explanation:
. B (Plane is here)
. .
. .
A . . . . . . . C
BC = 500 ft
Angle (Ф) between AB and AC = 9 degrees
So,
Sin(Ф) = BC/AB
Since we need to know how much hypotenuse AB measures, Let's isolate it from the equation:
AB = BC / Sin (Ф)
AB = 500 ft. / Sin (9)
AB = 500 ft./ 0.156
AB = 3,205.13 ft.
