zavuch27 [327]

Answer:

a) 0.2

b) 0.2

c) 0.5

Step-by-step explanation:

Let S be the event "the car stops at the signal.

In the attached figure you can see a tree describing all possible scenarios.

For the first question the red path describes stopping at the first light but not stopping at the second. We can determine the probability of this path happening by multiplying the probabilities on the branches of the tree, thus

P(a)=0.4\times0.5=0.2

For the second one the blue path describes the situation

P(b)=0.4\times 0.5=0.2

For the las situation the sum of the two green path will give us the answer

P(c)=0.6\times 0.5 + 0.4\times 0.5=0.3+0.2=0.5

Give an example of a function g(x) such that has vertical asymptotes at x = −1 and x = 2.
BigorU [14]

Answer:

\frac{69420}{(x+1)(x-2)}

Step-by-step explanation:

An asymptote of a vertical line is one that the graph can't exactly reach, but can get as close as you want it to be (as long as the distance is not 0), while the x- or y-coordinates tend to plus/minus infinity. An example of where this happens is when filling in the x-value would result in a zero in the denominator, hence the answer.
