1 answer:

5 0

3x^2−2x+7=0
3x^2−2x+1/3+7−1/3=0
3(x^2−2x/3+1/9)+7−1/3=0
3(x−1/3)^2+(21−1)/3=0
3(x−1/3)^2=−20/3
(x−1/3)^2=−20/9

oee [108]

Answer:

1/6

Step-by-step explanation:

There are 2 numbers greater than 4 on a die (5 and 6).

A spinner divided into 12 equal sectors numbered 1 through 12 has 6 even numbered sectors.

Therefore, the probability is:

P = (2/6) (6/12)

P = 1/6
