The statement is False.
For this, it is enough to show a case in which the subtraction of two positive numbers is negative.
For this, we must choose two numbers.
Suppose we want to subtract the following numbers:
Number 1: 5
Number 2: 10
Subtracting both numbers we have:
We observe that the result is negative. Therefore, the given conclusion is false.

Counterexample:
Answer: Bonnie must purchase 25 square feet of cloth.
Step-by-step explanation:
In order to waste the least amount of material, the length of each side of the square piece of cloth must be equal to the diameter of the circular banner that she wants to cut out. The formula for determining the circumference of a circle is expressed as
Circumference = πd
Where
d represents the diameter of the circle
π is a constant whose value is 3.14
Since banner will have a circumference of 15.7 ft, then
3.14d = 15.7
d = 15.7/3.14
d = 5 ft
Area of the square cloth needed is
5² = 25 square feet

Step-by-step explanation:
(a)
The median is represented by the solid vertical line inside the box, that is
median = 58
(b)
The interquartile range is the difference between the upper and lower quartiles.
The upper quartile is the value on the right side of the box, that is 72
The lower quartile is the value on the left side of the box, that is 34
Interquartile range = 72 - 34 = 38
(c)
The range is the difference between the maximum and minimum values
The maximum is indicated by the vertical bar on the right outside the box
The minimum is indicated by the vertical bar on the left outside the box
Range = 86 - 10 = 76
Answer:
81
Step-by-step explanation:
Average | x = 81
Count | n = 5
Sum | Sum = 405
Solution:
The average (mean) is equal to the sum of all the data values divided by the count of values in the data set.
Average = Sum / Count
= 405 / 5
= 81
