Answer:
The expected value of profit is -$0.65.
Step-by-step explanation:
The rules of the lottery are as follows:
- You pay $1 and pick a number from 000 to 999.
- If your number comes up, you win $350, which is a profit of $349.
- If you lose, you lose $1.
The probability of winning is, <em>P</em> (W) = 0.001.
Then the probability of losing will be,
P (L) = 1 - P (W)
= 1 - 0.001
= 0.999
Let the random variable <em>X</em> represent the amount of profit.
The probability distribution table of the lottery result is as follows:
<em>Result X P</em> (<em>X</em>)
Win +349 0.001
Lose -1 0.999
The formula to compute the expected value of <em>X</em> is:
Compute the expected value of profit as follows:
Thus, the expected value of profit is -$0.65.
The answer would be 20
A squares sides are equal and there are 4 of them so you take 80 (the total perimeter) and divide that number by 4 (number of sides) and you get 20

Answer:
6
Step-by-step explanation:
Each centimeter is equal to .01 meters
Or 100 centimeters = 1 meter
So if we convert Paula’s painting perimeter of 1.47 meters to centimeters, it would be 147 centimeters.
Now, since each ribbon comes in pieces that are each 25cm, we know are left with an easy division problem 147 divided by 25 or 5.88.
Since she needs the least amount of ribbons that it would take to wrap around the perimeter of the painting, we know it would be 6 because 6x25 = 150cm.
I agree with you. I added the mixed numbers and got 4 1/10 and that’s not an option.
