Answer:

Step-by-step explanation:

WITHOUT replacement of first card drawn:

P(a 10 is drawn) = 13/52 = 1/4

P(the next draw is a 10) = 12/52 = 3/13

P(drawing two 10s without replacement of the first draw) = (1/4)(3/13) = 3/52

WITH replacement of first card:

P(two 10s are drawn) = P(first card is a 10)*P(first card is a 10) = (4/13)(4/13) =

Plz help me, I have others I need help with​
lisov135 [29]

Step-by-step explanation:

That function is a line that goes through the origin (0,0).

You only need one more point to be able to draw it.

Take x=4,5 the corresponding value of y is exactly what you want to know, the number of miles the lava moved after 4,5 hours.

So y = 6 * 4,5 = 27

Your second point is (4,5 , 27).

Now you can draw your line.
