The number of cars entering a roadway at a specific exit during the morning rush hour traffic (6AM to 9AM, M-F) is a random vari
rusak2 [61]

Answer:

0.5

Step-by-step explanation:

This is an example of mutually exclusive event in which two or more events cannot occur at the same time or in a single performance.

Therefore, the probability the number of cars entering the roadway is between 4 and 6 cars per minute (inclusive) implies that it is either 4, 5 or 6 cars enter in a minute. Since we have an average of 6 cars per minute, the probability of each of the event occurring is 1/6. This can therefore be calculated as follows:

P(4 or 5 or 6) = (1/6) + (1/6) + (1/6)

                      = 3/6

                      = 1/2

                      = 0.5

Therefore, the probability the number of cars entering the roadway is between 4 and 6 cars per minute (inclusive) is 0.5.

Francium has a decay rate of 50% every 22 minutes. How much of an initial amount of 4.8 grams would be left after 88 minutes?
Jlenok [28]

Answer:

0.65g

Step-by-step explanation:

Decay rate = 50%

Decay rate = 0.5

A = Aoe {}^{ - kt}

where Ao = initial amount at start, k = rate of decay or growth, t = time, e = euler's number and A = value at time 't'

Ao = 4.8

t = 88/44 = 4

k = 0.5

substitute these values in the equation

A = 4.8e {}^{ - 0.5 \times 4}

A = 0.6496

A  = 0.65 \: (2dp)

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
kompoz [17]

Answer:

The fourth option gives the result.

Step-by-step explanation:

We have to find f(x) and g(x) from options given such that y = f[g(x)] is equivalent to y = \frac{8}{\sqrt{2x + 4}}.

Here, the fourth option gives the result.

If f(x) = \frac{8}{\sqrt{x} } and g(x) = 2x + 4, then the composite function f[g(x)] = \frac{8}{\sqrt{2x + 4}}

⇒ y = \frac{8}{\sqrt{2x + 4}} ( Answer )
