There are 6 sides of the die, let us say that side 1 is
S1, side 2 is S2 and so on.
Assigning a value of 3 to S1, so the probabilities are:
Probability
S1 = 3 3/8
S2 = 1 1/8
S3 = 1 1/8
S4 = 1 1/8
S5 = 1 1/8
S6 = 1 1/8
total = 8
The combinations that the sum of the two rolls will be 4
are:
S1 and S3
S3 and S1
S2 and S2
So the total probability is:
P = (3/8) * (1/8) + (1/8) * (3/8) + (1/8) * (1/8)
P = 0.1094 = 10.94%
So there is about 0.1094 or 10.94% probability that the
sum will be 4.

Answer:
170.72
Step-by-step explanation:
Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
I don’t know what some of that means but I can do the start for you? You rearrange
2x-y=1.
To do this, you +y to both sides, giving you 2x=1+y and then you minus 1, giving you 2x-1=y
Which can be rewritten the other way round to make it slightly easier
y=2x-1
You also have y=5x-5
These are both straight line equations and are now in the form y=mx+c
To sketch these graphs I would do two tables.
X -3 -2 -1 0 1 2 3
Y
For this, you now substitute each of the values for X into one of the equations you have. This is 2x-y=1 (2x-1=y)
X -3 -2 -1 0 1 2 3
Y -7 -5 -3 -1 1 3 5
You may have noticed a pattern there, the y values increased by two each time. This makes it linear. You would plot that line, onto an axis, using the coordinates you now have.
So, (-3, -7), (-2,-5), (-1,-3), (0,-1), (1,1), (2,3), (3,5)
Then I would do the same for the second equation, and plot that too.
X -3 -2 -1 0 1 2 3
Y -20 -15 -10 -5 0 5 10
You may have spotted this time the values increased by 5.
Then again plot this line using the coordinates shown.
I honestly have no idea what it means by “the line system on a corporate” but if that means on an axis then there’s your answer. If not then I do not know.
Hope this helps?
