12x+8 = 2(5x+6)
12x+8 = 10x+12
12x-10x = 12-8
2x = 4
x = 2

then DE = 5x+6 = 5(2)+6 = 16

Probability of survival of one disk, p=1-0.05=0.95
If there are n drives, and failures are independent (e.g. mechanical wear and tear, and not a lightning strike or a current spike), then
Probability of survival = p^n
(a) for two disks, P(2) = 0.95^2=0.9025
(b)for three disks P(3) = 0.95^3 = 0.8574

A student claims that 3x + 2y = 5xy. Use a visual representation to show whether this is true or false

Ket [755]

Answer:

It is true, except when x = 2/5, since it is an asymptote.

Step-by-step explanation:

3x=5xy-2y

3x=y(5x-2)

3x/5x-2=y

5x-2=0 -------> 5x=2 --------> x=2/5
