Answer:
4.356 × 10⁶ square feet or 4.356 × 10⁶ ft² of pizza per year
Step-by-step explanation:
Scientific notation is a means, method or way that is used in mathematics to write very large or small real numbers in a very short form or compressed form.
Scientific notation uses exponents or 10 raised to the power of a particular number to write huge or small real number in a decimal form.
In the question, we are asked to express the area in square feet as a scientific notation.
The area = 4,356,000 square feet of pizza per year
4,356,000 square feet of pizza per year in scientific notation =
4.356 × 10⁶ square feet of pizza per year.

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.

Generally, you are told to approach these by "clearing fractions". That is, you generally multiply the equations by the least common denominator so all fractions and mixed numbers become integers.
Alternatively, you can simply do the arithmetic using the numbers given. You learned a long time ago how to add, subtract, multiply, and divide mixed numbers and fractions. Do these operations as necessary to solve the equations.
Answer:
71
Step-by-step explanation:
1/71 * ? = 1
1/71 * x = 1 [consider 'x']
x = 1/(1/71)
x = (1/1)/(1/71) [1 = (1/1)]
x = (1/1)* (71/1)
x = 71.
Hope you're satisfied.
