Answer:
1 11/12
Step-by-step explanation:
5 2/3 - 3 3/4
break off 1 from 5:
5 2/3 = 4 5/3
subtract the whole numbers:
4 - 3 = 1
find a common denominator so you can subtract the fractions, and multiply both the numerator and the denominator by the same number:
x 4 =
x 3 =
20/12 - 9/12 = 11/12
so your final answer is 1 11/12
i hope this helps! :)

Answer: Prokhorova is more outstanding.
Step-by-step explanation: To compare scores from different distributions, first standardize it:
z-score =
where
x is the individual mean you want to compare
μ is the mean of the population
σ is standard deviation
For <u>Gertrud Bacher</u>:
z-score =
z-score = (s)
The negative sign indicates Bacher's mean is less than the mean
For <u>Yelena Prokhorova</u>:
z-score =
z-score = 2 (cm)
The positive sign indicates Prokhorova's mean is more than the mean.
Using z-score table, you determine the percentiles are:
For Bacher: Percentile = 5.5%
For Prokhorova: Percentile = 97.7%
Bacher's percentile means she is above 5.5% of the participants, while Prokhorova is 97.7% above the other competitors, which means Prokhorova have a better performance and deserves more points.
