Answer:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.
One dice has 6 sides and two dice will give us 12 sides with 36 possibilities
it will be 9/36=.25
so it will have 25% chance of the two dice to have a sum of 9
Answer:
B
Step-by-step explanation:
One way to tell is to put both equations into slope-intercept form. That form is usually written
where <em>m</em> is the slope and <em>b</em> is the y-intercept.
Solve the first equation for y.

The slope of this line is -3, and its y-intercept is 5/2.
Solve the second equation for y.

The slope of this line is -3 and its y-intercept is 2.
The lines are parallel because they have the same slope and <u>different</u> y-intercepts. There is no solution to the system.
You would multiply both and then the answer you would put into ratio form
