Answer:
5.5
Step-by-step explanation:
2,3,3,4,5,7,8,8,8,10,10,12
The mean of this data is 7.5. So what you are trying to figure out is the mean between 2 and 7. Since that is 3 and 4 it would be 3.5. So 3.5 is the Q1. Now you have to figure out the mean between 8 and 12. That is 9. This is Q3. You have to subtract 9-3.5 and that is the interquartile range. So 5.5 is the answer. I hope that made sense.
7(x - 3) + 3(4 - x) = -8
7x - 21 + 12 - 3x = -8
7x - 3x = -8 + 21 - 12
4x = 1
x = 1/4
Answer:
24x4 24 divided by 4 24+ 4 it should be one of these hope this helps

Answer:
= 12 cm^3
Step-by-step explanation:
V = Bh where B is the area of the base and h is the height
For a triangular prism, the base is the triangle
A = 1/2 bh for the triangle
= 1/2 (6*2)
= 6 cm^2
To find the volume for the triangular prism
V = Bh
= 6 * 2
= 12 cm^3
