x/5(10-11)=2 according to P.E.M.D.A.S. solve 10-11 first you should get -1 so your new equation will be x/5(-1)=2 then add 1 to both sides leaving you with x/5=3

lastly multiply both sides with 5, yous final answer should be x=15

x/5(10-11) Remember PEMDAS and remember to isolate the variable;)

1. x/5(10-11) =2 (subtract)

2. x/5 * -1 =2 (add +1 to each side)

3. x/5= 3 (multiply both sides by five)

4. x=15

Larry reads that 1 out of 4 eggs contains salmonella bacteria, so he never uses more than 3 eggs in cooking. If eggs do or don't

aleksley [76]

Answer:

57.8125% or approx. 57.8%

Step-by-step explanation:

There is a 1/4, or 25%, or 0.25 chance that an egg has salmonella.

Thus, there is a 75%, or 0.75 chance that an egg DOESN'T contain salmonella.

Let's find the probability that all 3 of Larry's eggs are free from salmonella. Larry would have to hit that 75% chance 3 times in a row. The chance of that happening is:

0.75 * 0.75 * 0.75 = $0.75^3$ = 0.421875

From this, we can deduce that if there is a 0.421875 (42.1875%) chance that all eggs are safe to eat, there must be a...

1 - 0.421875 = 0.578125

...0.578125 (57.8125%) chance that 1 or more of Larry's eggs do have salmonella.

Answer: approx. 57.8% or 57.8125%
