The ratio of their perimeters is still 7:20. The poster is a rectangle shape. If the length of each side of a poster is proportional to the other by a certain ratio, the sum of the lengths of all sides is also proportional by the same ratio. You can suppose the lengths of four sides of poster A are 7a, 7b, 7c, 7d, so poster B has 20a, 20b, 20c, 20d. (7a+7b+7c+7d)/(20a+20b+20c+20d)=7(a+b+c+d)/20(a+b+c+d)=7/20.

Answer:
The box plot will have its left tail longer than the right tail becuase a few exceptionally low prices make the distribution skewed to the left.
Step-by-step explanation:
As seen in the attached file, the box plot has its left tail longer than the right tail because of the exceptionally low prices that is :$2
Firstly arranging the data in increasing order:
$2,$2,$25,$25,$26,$26,$27,$27,$28,$28,$30
Median of the data = 26 (since there are odd numbers)
Lower quartile (Q1) = 25
Upper quartile (Q2) = 26
By plotting the box plot we conclude that the left tail is longer than the right tail.
3x^2 - 2x^2y + 2xy^2 + 4y^2 + xy^2 - y^2 + 2x^2y
= 3x^2 + 3y^2 + 3xy^2
answer
3x^2
3y^2
3xy^2
2.8y + 6 + 0.2y = 5y – 14
Simplify the left side:
3y +6 = 5y-14
Subtract 3y from both sides:
6 = 2y -14
Add 14 to each side:
2y =20
Divide both sides by 2:
y = 20 / 2
y = 10
