The mean is 0.23 I will comment the outlier median and Mode
I think the answer is the range increases by 8
1 feet = 12 inches
16 feet = 16 x 12
16 feet = 192 inches
I section = 2 2/3 inches
192 ÷ 2 2/3
= 192 ÷ 8/3
= 192 x 3/8
= 578/8
= 72
It can be cut into 72 sections.
24 mm^2
Reasoning:
The area of the big triangle will be: (6+4+2)(5)(0.5). The answer will be equal to 30 mm^2. The area of the smaller triangle will be: (4)(3)(0.5). The answer will be 6 mm^2. Next, subtract the area of the larger triangle by the smaller triangle (30-6). The final answer will then be 24mm^2.
Sorry if this may have been confusing. I had to do this on my phone.
