Step-by-step explanation:
Using the mean concept, it is found that the value of the number that was removed was of 4.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
The mean of five numbers is 8, hence, the sum of the numbers is given by:
S = 5 x 8 = 40.
If one of the five numbers is removed, the mean becomes 9, hence, the sum of the four numbers is given by:
S = 4 x 9 = 36.
The difference is:
40 - 36 = 4.
Hence, the value of the number that was removed was of 4.

Answer:
509in²
Step-by-step explanation:
Formula for calculating the area of a regular hexagon is given as:
A=(3√3a²)/2
'a' is one of the sides of the hexagon
Given a = 14in
Area = 3√3/2 × 14²
Area = 3√3/2 × 196
Area = 3√3 × 98
Area = 509.22in²
Area of the regular hexagon is approximately 509in²
