Markov Chains question: Can someone explain how to solve this?

If it rains today, then there's a 10% chance of rain tomorrow. If it doesn't rain today, then there's a 55% chance of rain tomorrow. Today is nice and sunny. What is the chance of rain 3 days from today?

brandon has 4344 video games.  

step-by-step explanation

7373 - 2929 = 4344

pls let me know if it was correct

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
