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.
Answer:
Step-by-step explanation:
Look at both terms separately, and isolate each "part."
i.e. 12x^4y^2 becomes 12, x^4, y^2
So the problem becomes:
12, x^4, y^2 and
30, x^3, y^1
Then, find the GCF of each term,
30 and 12 - 6
x^4 and x^3 - x^3
y^2 and y^1 - y^1
Hope it helps :) and let me know if you want me to elaborate.
Answer:
Given the radical form: 
Use the exponent rules:
![\sqrt[n]{a^m} = (a^m)^{\frac{1}{n}} = a^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5Em%7D%20%3D%20%28a%5Em%29%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%20%3D%20a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)
we can write 
as:
then;
= 
Therefore, in exponential form is
There are two prime numbers between 20 and 30: 23 and 29.
To find the percentage each number is of 125, you’d divide the number by 125 and move the decimal in the answer 2 places to the right to turn it to percentage notation (from decimal notation), so you’d solve 23/125 and 29/125.
23/125= .184
Moving the decimal two places to the right makes this 18.4%
29/125= .232
Moving the decimal two places to the right makes this 23.2%
X has two possible values of which you are to pick/use only one: 18.4 and 23.2
The number of rows of beans that are in the garden is 24 rows.
<h3>How many rows of beans are in the garden?</h3>
The first step is to convert feet to inches.
1 feet = 12 inches
30 x 12 = 360 inches
The second step is to divide 360 inches by 15 inches: 360 / 15 = 24 rows
