The reason for the scenario is because the cocoa was mixed with hot water but some cocoa settled as it cooled because the solubility went down.

  • Solubility simply means the amount of a substance that can be used in dissolving an amount of solvent at a particular time.

  • In this scenario given, it should be noted that the brown solids in the bottom of the mug were due to the fact that the solubility went down when the cocoa was mixed with water.

In conclusion, from the complete question, the correct option is C.

3x+4y=23 <br>2y-x=-19 <br>what is the solution (x,y) to the system of equations above?
Zanzabum
3x+4y=23
2y-x= -19/ multiply -2

4y + 3x = 23
-4y - 2x = 38
_______________
X = 61

2y - x = -19
2y - 61 = -19
2y = 61 -19
2y = 42

Answer:

I used the function 1-proportion z-interval on the calculator, where I inputted

  • Successes(x) = 64
  • Sample size(n) = 593
  • Confidence Level(C level) = 0.99

It would result in zInterval_1Prop 64,593,0.99: stat.results, where the values are shown below as:

  • Lower bound (CLower) = 0.075105
  • Upper bound (CUpper) = 0.140747
  • test statistic (p^) = 0.107926
  • Margin of error (ME) = 0.032821

Therefore, the 99% confidence interval would be around 0.11 ± 0.03 or range from 0.08 to 0.14.
