In the given game of rolling a die. these are the possible winnings.
- If the number showing is even(2, 4, or 6) or 1, you win $3.
- If the number showing is either 3 or 5 you win $0.
There are 6 sides in the die.
(i)The probability distribution of x.
Let x be the amount won
Therefore:
Probability distribution of x.
(ii) Expected amount of dollar won
Expected Amount
You would expect to win $2.
Use the formula m = y2 - y1 / x2 - x1
-2 - 3 / 7 - 4
-5 / 3
the slope of the line in simplest form is -5/3

Answer:
3 15/17 hours
Step-by-step explanation:
Sue's rate of completion is ...
1/6 order per hour
Jim's rate of completion is ...
1/11 order per hour
Assuming they can appropriately divide the work, their total rate of completion will be ...
(1/6 + 1/11) = (11+6)/(66) = 17/66 . . . . order per hour
The time for one order is the inverse of that: 1/(17/66) ...
66/17 hours per order = 3 15/17 hours per order
Working together, it will take Sue and Jim 3 15/17 hours to fill the order.
Answer:
x=-15/8 or -1 7/15 OR x=-5/3 or -1 2/3
Step-by-step explanation:
Subtract 15 from both sides
8x=-15
Divide 8 on both sides
Now you get your answer
x=-15/8 or -1 7/15
OR
Combine like terms
9x+15=0
Subtract 15 from both sides
9x=-15
Divide 9 from both sides
x=-15/9
Simplify
x=-5/3 or -1 2/3
