A slot machine has 3 dials. Each dial has 30 positions, one of which is "Jackpot". To win the jackpot, all three dials must be i

n the "Jackpot" position. Assuming each play spins the dials and stops each independently and randomly, what are the odds of one play winning the jackpot?
1/30 = 0.03 or 3%


3/(30+30+30) = 3/90 = 0.33 or 33%


3/(30×30×30) = 3/27000 = 0.0001 or 0.01%


1/(30×30×30) = 1/27000 = 0.00003 or 0.003%

Nina's monthly budget is $2,250. Every month she makes the following payments: $175 for insurance, $129 for utilities, $283 for
choli [55]
The total costs that Nina would have to pay is the sum of the cost of insurance, utilities, and taxes.
                               C = $175 + $129 + $283 = $587
The highest house payment she could afford is then the difference between her budget and the costs,
                                  P = $2,250 - $587 = $1663
Thus, the answer would be letter B. House B because all the rest of the monthly payment are way over her budget.

satela [25.4K]

Answer:

$(55-3m) is the amount of money she has left

Step-by-step explanation:

In this question, we are asked to give an expression to represent how much money was left after Sarah had bought some certain stuffs at some prices using the money she received at her birthday.

Firstly, we identify that the total amount of money she has to spend is $55.

Now let’s project her total spendings. She bought 3 shirts with each shirt costing $m.

The total amount spent on the shirts is thus; 3 * $m = $3m

The amount of money she has left is the difference.

Mathematically, this is equal to $55 - $3m
