Which shows how to use similar right triangles to find the equation of the line through (0,6) and any point, (x, y), on the line?
y-0
m
0
So y = ma.
(x, y)
(1. m+b)
y - b
2-0
m+b-b
1-0
so y = mx + b.
(0,b)
(0,0)
2-0
y-b
m+bb
1 - 0
SO X = my + mb.
y-1
m
= i, so y — b = mx +b.
Done

Isabel graphed the following system of equations. 2x – y = 6 y = -3x + 4 she came up with the solution (2,-2). what were the 3 steps she did to get that solution? (make sure they are in the correct order)

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if

Assume that there is a 11% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on four independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
