Answer:
Han's mixture, Claire's mixture
Step-by-step explanation:
I figured out the percentage of orange juice for each person's mixture:
For Claire:
2 1/2 + 1/3 = 2 5/6
2 5/6 as a decimal: about 2.8
Now find what percent of Claire's total mixture was orange juice:
100 * 1/3 / 2.8 = about 11.9%
For Han:
1 2/3 + 1/4 = 1 11/12
1 11/12 as a decimal: about 1.9
Now find what percent of Han's total mixture was orange juice:
100 * 1/4 / 1.9 = 13.2%
So, Han's mixture is stronger, since his has the higher percentage of orange juice concentrate
Answer:
The probability of a student receiving a C in the course is p=0.3.
Step-by-step explanation:
We have a absolute frequency for each of the grades (A to F), of a total of 300 course tests.
It is assumed that this sample gives a dood estimation of the distribution of the grades. Then, we can estimate the probability of obtaining a C in the course usign the relative frequency for C.
The relative frequency is calculated as the division between the absolute frequency (in this case, 90 for a C grade) and the size of the sample (in this example, 300).
![p_C=\dfrac{X_C}{N}=\dfrac{90}{300}=0.3](https://tex.z-dn.net/?f=p_C%3D%5Cdfrac%7BX_C%7D%7BN%7D%3D%5Cdfrac%7B90%7D%7B300%7D%3D0.3)
You get 75,015.45 without rounding. once you round, you get 75,015.5
