Which one am i suppose 2 do ?
Answer:
Radical:
6 = 3.1x + 1
/3 = /2p-5
NOT Radical:
2/2 + y = -10
4-3.75 = n3.17
Step-by-step explanation:
got it right on edge
Expected value is the sum, for all possible outcomes, the value of each outcome times its probability. In other words,
E[X]=sum x*P(X=x)
For this given situation there are 4 outcomes (out of 36) that rolls a sum of 5 [1,4; 2,3; 3,2; 4,1], so p(5)=4/36=1/9 and its value is $6.
There are 3 possible outcomes for a sum of 10 (again out of 36), so P(10)=3/36=1/12, with a value of $9.
All the other outcomes carry zero value, so the expected payoff is therefore
E[X]=sum x*P(x)
=$6*(1/9)+$9*(1/12)+$0(29/36)
=$(2/3+3/4)
=$17/12
=$1.42 (approx.)
So the expected payout is $1.42, not forgetting that it costs a certain amount to play the game.
Hello!
<h2>Answer:</h2>
Carla will pay $300.30 for the gold ring.
<h2>Explanation:</h2>
Sales tax is added on to the total cost of the item. We need to figure out how much tax is on the ring.
To do that, we must calculate 10% (or 0.10) of $273.00.
273 × 0.10 = 27.3
Now, add the tax to the cost of the ring.
273 + 27.3 = 300.3
