Answer:
We are given a information that:
A school for learning foreign languages has 72 students who learn German, and 54 of those students also learn Russian. There are 12 students who do not learn German but learn Russian, and 10 students do not learn either German or Russian.
Based on this information we can make our table as:
Learn German don't learn German Total
LR 54 12 66
DNLR 18 10 28
Total 72 22 94
<em>DNLR represent do not learn Russian and LR represent learn Russian.</em>
Now for finding the conditional relative frequency table we divide each of the quantities by the total sum of each row i.e. first row is obtained by dividing by 66, second by dividing by 28 and third by dividing by 94 to obtain the table as:
Learn German don't learn German Total
LR 0.82 0.18 1
DNLR 0.64 0.36 1
Total 0.77 0.23 1
Answer:
Oil: 10.5 oz Vinegar: 3.5 oz
Step-by-step explanation:
If the amount of vinegar is the variable x than the amount of oil is 3x. this means that x+3x=14 or 4x=14. Which means x=3.5 so vinegar is 3.5 while oil is three times that or 10.5.

I hope this is correct!
Not sure about the summer part, but the answer should be 1 / 6. Maybe your question is wrong.
