Answer:
2677 mi^2
Step-by-step explanation:
Think the shape as an complete rectangle :
The area of the rectangle is calcluated by multiplying height*width
(24+12+19)*55 = 3025 mi^2 now subtract the area of the missing part using same area calculation method:
12*29 = 348 mi^2 the area of the figure:
3025 - 348 = 2677 mi^2
Tax = 7 1/4% = 29/4
After tax, it would be, 89.79 + 89.79*29/4*100 = 89.79 + 2589.41/400
= 89.79+6.47 = $96.26
The dataset 78 is an outlier of the dataset
<h3>How to determine the true statement about the outlier?</h3>
The dataset is given as:
1, 12, 13, 15, 18, 20, 35, 37, 40, 78
Where
Q1 = 13
Q3 = 37
The boundaries of the outliers are given as:
L = Q1 - 1.5 * (Q3 - Q1)
U = Q3 + 1.5 * (Q3 - Q1)
Substitute the known values in the above equation
L = 13 - 1.5 * (37 - 13) = -23
U = 37 + 1.5 * (37 - 13) = 73
This means that the data elements outside the range -23 to 73 are outliers.
78 is outside this range
Hence, 78 is an outlier of the dataset
