Answer:
(a) 42.25 km
(b) 616.85 km
(c) 32.31 cm
Step-by-step explanation:
(a) 1 cm on map: 4225000 / 100000 = 42.25 km on ground
(b) 14.6 cm on map: 42.25 x 14.6 = 616.85 km on ground
(c) 1365 km on ground: 1365 / 42.25 = 32.31 cm on map
Answer:
The duration of the randomly selected class is 52.6 minutes.
Step-by-step explanation:
The random variable <em>X</em> is defined as the duration of a professor's class.
It is provided that, 
.
The pdf of <em>X</em> is:
It is provided that the probability that the duration of the class is longer than <em>c</em> number of minutes is 0.468.
That is, P (X > c) = 0.468.
Compute the value of <em>c</em> as follows:
![P(X>c)=0.468\\\\\int\limits^{55.5}_{c}{\frac{1}{55.5-49.2}}=0.468\\\\\frac{1}{6.3}\times [x]^{55.5}_{c}=0.468\\\\55.5-c=2.9484\\\\x=52.5516\\\\x\approx 52.6](https://tex.z-dn.net/?f=P%28X%3Ec%29%3D0.468%5C%5C%5C%5C%5Cint%5Climits%5E%7B55.5%7D_%7Bc%7D%7B%5Cfrac%7B1%7D%7B55.5-49.2%7D%7D%3D0.468%5C%5C%5C%5C%5Cfrac%7B1%7D%7B6.3%7D%5Ctimes%20%5Bx%5D%5E%7B55.5%7D_%7Bc%7D%3D0.468%5C%5C%5C%5C55.5-c%3D2.9484%5C%5C%5C%5Cx%3D52.5516%5C%5C%5C%5Cx%5Capprox%2052.6)
Thus, the duration of the randomly selected class is 52.6 minutes.
