The relationship between what Alex typed and what Tasha typed can be represented by a simple equation.
Where: 'A' the number of words Alex typed in a minute and T is the number of words typed by Tasha in a minute.
Therefore Tasha typed 43.9 words in one minute.
Hope this helps!

Step-by-step explanation:
The area of a square is the square of the side length.
For example, (√125)² = 125.
__
The side length of a square is the square root of the area.
For example, √98 = √(7²·2) = 7√2.
<h2>Answer:</h2>
A)
Mean for:
Sample Z -- 447.5
Sample Y-- 409.3
B)
Sample Y has larger deviation from the mean.

A)
For sample Z--
The mean is calculated by:
Ratio of sum of all the data points of Z-sample to the total number of points i.e. 10.
Similarly for sample Y--
The mean is calculated as follows:
B)
As we could see that the data Y has a greater spread from the mean as compared to the sample Z.
As all the points in the sample Z are close to the mean and have less spread.
The standard deviation is most commonly used to measure the spread of the data.
Standard deviation of sample Z is: 10.651
Standard deviation of sample Y is: 16.9944
Hence Sample Y have larger deviation from the mean.
