A science teacher has a supply of 50% sugar solution and a supply of 80% sugar solution. How much of each solution should the te
mash [69]
How much of each solution should the teacher mix together to get 105 ML of 60% sugar solution for an experiment?

1. Look at how 60% is closer to the solution of lower concentration (50%). You can deduce that you will be mixing a higher volume of the 50% solution.

2. All 4 answers add up to 105ml.

3. The intuitive answer is the first option:
70 ML of the 50% solution and 35 ML of the 80% solution

4. Let's check whether point 3 is true.
70ml/105ml X 0.5 + 35ml/105ml X 0.8 = (35 + 28)/105= 63/105= 60% / 105 ml = 105ml of 60% sugar solution

Ostrovityanka [42]

Answer:

The proportion of the sample that does not have a two-year or four-year college degree is 0.7355.

Step-by-step explanation:

Sample of 310 people.

186(only high school) + 42(only some college) did not have have a two-year or four-year college degree.

So

p = \frac{186+42}{310} = 0.7355

The proportion of the sample that does not have a two-year or four-year college degree is 0.7355.
