1 oz of walnuts were mixed with 4 oz of peanuts which cost $4/oz to make mixed nuts which cost $5/oz. what is the price per oz o
Zanzabum
Call w the unknwon price of the walnuts, then:

total cost of walnuts = 1oz *  w

Total cost of peanuts = 4 oz * $4/oz = $16

Total cost of nuts = 5oz * $5 /oz = $25

=> 1oz*w + $16 = $25 => w = ($25 - $16) /1oz = $9/oz

Verfify:

1oz * $9/oz + 4oz * $4/oz = $9 + $16 = $25, which is equal to 5oz * $5/oz.

Answer: $9 per oz.

To win the game, Elena has to roll an even number first and a number less than 3 second. Her probability of winning is 6/36.
Nitella [24]

<u>Answer:</u>

  • Prob (Marta winning) < Prob (Elena winning) : Case 1st, 3rd & 5th
  • Prob (Marta winning) = Prob (Elena winning) : Case 2nd
  • Prob (Marta winning) > Prob (Elena winning) : Case 4th

<u>Step-by-step explanation:</u>

Elena outcomes of winning, first even no. & second no. = 3 : (2,1) , (2,2) , (4,1) , (4,2) , (6,1) , (6,2). So, Probability (Elena willing) = favourable outcomes / total outcomes = 6 / 36

  • Margie dice sum '7' outcomes = (2,5) , (5,2) , (3,4) , (4,3). So, Prob = 4/36
  • Margie dice sum '6' outcomes = (1,5) , (5,1) , (2,4) , (4,2) , (3,3). So, Prob = 6/36
  • Margie dice sum '2' or '9' outcomes = (1,1) , (3,6) , (6,3) , (4,5) , (5,4). Prob = 5/36
  • Margie dice sum '>9' outcomes = (3,6) , (6,3) , (4,5) , (5,4) , (4,6) , (6,4) , (5,5) , (5,6) , (6,5) , (6,6). Prob = 10/36
  • Margie dice sum '>2,<5' outcomes = (1,2) , (2,1) , (2,2) , (1,3) , (3,1)  = 4/ 36
