Please help Thanks.​

Answer 1

The answer is 25.

Explanation:

It says how many students identified 20 flowers or less which means you have to look at 0-8, 7-13, and 14-20 under "Number of Flowers" So add the number of students under 0-8, 7-13, and 14-20 which is 5, 14, and 6. So the answer comes to 25.

Answer 2

The percentage of students that identifies less than 20 flowers is 25% (5+14+6)

25% of 150 is

`150\cdot(25)/(100)=\150\cdot(1)/(4)=(150)/(4)=37.5`

So, about 38 students identifies 20 or less flowers correctly.
