Answer 1

Answer:

A lion was once sleeping in the jungle when a mouse started running up and down his body just for fun. This disturbed the lion’s sleep, and he woke up quite angry. He was about to eat the mouse when the mouse desperately requested the lion to set him free. “I promise you, I will be of great help to you someday if you save me.” The lion laughed at the mouse’s confidence and let him go.

One day, a few hunters came into the forest and took the lion with them. They tied him up against a tree. The lion was struggling to get out and started to whimper. Soon, the mouse walked past and noticed the lion in trouble. Quickly, he ran and gnawed on the ropes to set the lion free. Both of them sped off into the jungle.

Moral of the Story

A small act of kindness can go a long way.

Answer 2

Step-by-step explanation:

Donation by each student No. of students donated

Cumulative frequency

5 15 15

7 15 30

10 20 50

15 16 66

20 14 80

To find the mean we will add up total cost of packets , then divide by total number of packets.

So,

Mean =

(15+15+20+16+14)

(5×15+7×15+10×20+15×16+20×14)

Mean =(75+105+200+240+280)/80=900/80=11.26

As we can see that the donation of greatest number of student is Rs. 10 each, so the mode will be 10

As we can see there are 80 students arranged in increasing order of their respective donations. So, the middle one will be (80)/2=40

th

and 41

st

student in the list.
