What's the first and third quartile of -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 7, 7, 7

There are 14 total numbers.
Make a list of the 7 lowest numbers:
-5, -4, -3, -2, -1, 0 , 1
The first quartile is the middle value of the lower half of numbers
Since there are 7 numbers ( odd number), the middle value is the middle number, which is -2
Now make a list of the 7 highest numbers:
2, 3 , 4, 5 , 7, 7, 7
The 3rd quartile is the middle value of the higher half of numbers.
Again because there are 7 numbers ( odd number), the middle value is the middle number, which would be 5.
First quartile = -2
Third quartile = 5
Since there is nothing attached for me to help you I looked for a website that can find the answer with an explanation. It is called quickmath it’s like a math calculator . Hopefully that helps you .
Answer:
Acceleration = 3m/s²
Step-by-step explanation:
Here ,
Initial velocity = 30km/h
Final velocity = 0km/h
Time = 10s
Acceleration = ?
We know ,
A = v-u/t
or , A = 0-30/10
or, A = 30/10
A = 3m/s²
Therefore the acceleration is 3m/s²
