Answer: 8,100 cm^2
Step-by-step explanation: Area = S^2 so each side is sqrt(900) = 30cm
A square 3 times bigger has sides 30cm*3 = 90cm. The area for that square is 90^2 = 8,100 cm^2
Answer:
So in exponential form 
will be equivalent to 
Step-by-step explanation:
We have given the expression in radical form as
We have to find its equivalent in exponential form
We know that if any fraction is in radical form then if we write this in exponential form then in exponential form the exponent come inverse of its number
So can be written as
So in exponential form will be equivalent to
Using statistical concepts, it is found that:
- The mean practice time decreases because of the outlier.
- The median practice time does not change because of the outlier.
- The range increases because of the oulier.
<h3>What are the mean, the median and the range of a data-set?</h3>
- The mean is the sum of all observations divided by the number of observations.
- The median is the middle value, the value that separates the upper 50% from the bottom 50%.
- The range is the difference between the largest value and the smallest.
From their concepts above, we have that the mean and the range are influenced by outliers.
In this problem, the outlier is at the low end, of 15, hence:
- The mean practice time decreases because of the outlier.
- The median practice time does not change because of the outlier.
- The range increases because of the oulier.
