The porch light is an automatic switch that will start turning on at 19.00 - 19.30 or 20.00 - 21.00 at random. The lights will automatically go out at some point in time between 04:00 and 06:00 in the morning. Suppose it is known that tonight the light is on for t hours, the probability that the light is on for 9 < t < 10 hours is ...

If 19:00<=x<=19:30 and 4:00<=y<=6:00

Total time difference

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6
