A civil engineer is studying a left-turn lane that is long enough to hold seven cars. Let X be the number of cars in the line at
the end of a randomly chosen red light. The engineer believes that the probability that X = x is proportional to (x + 1)(8 − x) for x = 0, . . . , 7 (the possible values of X), i.e. P(X = x) = ( C(x + 1)(8 − x) for x = 0, 1, . . . , 7 0 otherwise 1. Determine the value of C. 2. Find the probability that X will be at least 5.

Explanation:
To calculate or compute the magnitude of the velocity at whichever point in time, you’ll need to multiply the constant acceleration pace times the amount of time difference and then adding the result to the initial velocity
While To calculate or compute the horizontal component, the magnitude of the vector will just be multiplied by the cosine angle referenced to the horizontal

Answer:
Source 2.
Explanation:
The efficiency of the ideal reversible heat engine is given by the Carnot's power cycle:
Where:
- Temperature of the cold reservoir, in K.
- Temperature of the hot reservoir, in K.
The thermal efficiencies are, respectively:
Source 1
Source 2
The power produced by each device is presented below:
Source 1
Source 2
The source 2 produces the largest amount of power.
