A month of the year is selected at random. What is the probability that it
has 31 days or starts with the letter J?*
1/6
3/4
7/12
2/3

1/6

Step-by-step explanation:

January and July both have 31 days in them so that makes 2/12 months and 2/12 simplified is 1/6

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
