Answer:
4th row will result in the greatest mean.
Step-by-step explanation:
We are asked to find the row with greatest mean from our given rows.
We will use formula 
, where,
,
,
Let us find mean of each row using above formula.
Therefore, mean of 1st row is 2.8.
Therefore, mean of 2nd row is 3.
Therefore, mean of 3rd row is 3.2.
Therefore, mean of 4th row is 4.2.
Since 4th row has the highest mean, therefore, 4th row will result in the greatest mean.
Answer:
Trapezoid
Step-by-step explanation:
perpendicular: They are perpendicular due to the fact they cross at right angles to each other. Another true instance of perpendicular lines we will see in nature is a football field. All four corners of a football field are perpendicular to every other.
In the trapezoid attached there aren't any perpendicular sides. A and B are both obtuse angles in this diagram, and C and D are both acute angles. However, now not all trapezoids appear like this. ... Definition B: A trapezoid is any quadrilateral with at the least one pair of parallel sides.

Answer: $284.80
look when you are trying to find the percent of a number you need to turn the percent into a decimal then multiply the decimal by the number:
1st. 40% as a decimal is 0.40 because as a fraction 40% is 40/100 so that means that 1.00 is 100 and 0.40 is 40%
2nd. Next, you do 0.40 x 712.00 = or
712.00
x 0.40
