Answer: The median for the students is 2 and the median for the teachers is 3.

Step-by-step explanation:

Ordering the data for the students from the dot points:

0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4.

n = 20 which is positive so median position is average of:

= (n / 2) and = (n + 1) / 2

= 20 / 2 = 21 / 2

= 10 = 10.5

2 is in position 10 2 is in position 10.5

Average = (2 + 2) / 2 = 2

Student median is 2.

Teachers

0, 1, 1, 1, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 6, 8

3 is in position 10 as well as in position 10.5.

= (3 + 3) / 2

= 3

Teacher median is 3.

Asher gave lemonade to 14 students

Solution:

Given that, A container has 12 and $\frac{3}{4}$ cups of lemonade

Asher gives each of his classmates $\frac{7}{8}$ of a cup of lemonade

To find: Number of classmates received the lemonade

From given question,

Total cups of lemonade = $12\frac{3}{4}$

$\rightarrow 12\frac{3}{4} = \frac{4 \times 12 + 3}{4} = \frac{51}{4}$

cups of lemonade received by each classmate = $\frac{7}{8}$

Thus, number of classmates received the lemonade can be found by dividing total cups of lemonade by cups of lemonade received by each classmate

$\rightarrow \frac{\frac{51}{4}}{\frac{7}{8}}=\frac{51}{4} \times \frac{8}{7}$

$\rightarrow 14.57$

Thus Asher gave lemonade to 14 students
