-50 cents
Step-by-step explanation:
The "Winnings" random variable has values -1 and 499
The associated probabilities are P(-1)= 999/1000; P(499)=1/1000
-----------------------------
Expected Value = -1(999/1000) + 499(1/1000) = -500/1000 = -50 cents
Answer:
1. 18
2. 6
3. ?
4. 3
5. 4
6. 1
7. 5
Step-by-step explanation:
1. 6 x 3 = 18
2. 2 + 4 = 6
3. ( I cant read the problem)
4. 6 - 3 = 3
5. 2 x 2 = 4
6. 3 ÷ 3 = 1
7. 6 - 1 = 5
8. 6 + 2 = 8
Given:
Cost of lunch per day = 1 meal and 2 snacks
C = 5.5 + 2(0.75) = 5.5 + 1.5 = 7
7 * 12 days = 84
Based on the choices, the best strategy would be:
<span> A. Make a table. Write the numbers 1 to 12 in the top row of the table (the number of days). In the first box on the second row, write $7. This is how much Rebecca spends in 1 day. In each of the next boxes in the second row, write the amount Rebecca spends by adding $7 to the previous amount. The answer in box 12 is the total amount Rebecca spent after 12 days.</span>
