The correct option regarding the data-sets represented by the box and whisker plots is:
B. The distribution for town A is positively skewed, but the distribution for town B is symmetric.
<h3>What does a box-and-whisker plot shows?</h3>
A box and whisker plot shows three things:
- The 25th percentile, which is the median of the bottom 50%.
- The median, which splits the entire data-set into two halfs, the bottom 50% and the upper 50%.
- The 75th percentile, which is the median of the upper 50%.
For data-set A, we have that:
- The 25th percentile is of 15.
- The 75th percentile is of 30.
Since 30 - 20 > 20 - 15, the distribution is positively skewed.
For data-set B, we have that:
- The 25th percentile is of 20.
- The 75th percentile is of 40.
Since 40 - 30 = 30 - 20, the distribution is symmetric.
Hence the correct option is:
B. The distribution for town A is positively skewed, but the distribution for town B is symmetric.

26=16x or x=1 5/8 because 6 and 11 are multiplied by 3
Answer:
6:5
Step-by-step explanation:
Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.
The algae is spherical in nature
Volume of the algae =4/3 pi r³
Volume of the algae = 4/3×pi×2.5³
Volume of the algae = 62.5/3 pi
Surface area = 4pi r²
Surface area = 4pi ×2.5²
Surface area = 25pi
Taking their ratio
surface area : volume ratio
= 25pi:62.5/3 pi
= 25 × 3/62.5
= 1.2
Hence the required ratio is 12/10 which is 6:5
