All you do is subtract the two numbers
Answer: A B
Group 1 0.25 0.75
Group 2 0.44 0.56
Step-by-step explanation:
Since we have given that
Number of people of A in group 1 = 15
Number of people of B in group 1 = 45
Total number of people in group 1 is given by
![15+45=60](https://tex.z-dn.net/?f=15%2B45%3D60)
Relative frequency of people of A in Group 1 is given by
![\frac{15}{60}=0.25](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B60%7D%3D0.25)
Relative frequency of people of B in Group 1 is given by
![\frac{45}{60}=0.75](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B60%7D%3D0.75)
Similarly, Number of people of A in group 2 = 20
Number of people of B in group 2 = 25
Total number of people in group 2 is given by
![20+25=45](https://tex.z-dn.net/?f=20%2B25%3D45)
Relative frequency of people of A in Group 2 is given by
![\frac{20}{45}=0.44](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B45%7D%3D0.44)
Relative frequency of people of B in Group 2 is given by
![\frac{25}{45}=0.56](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B45%7D%3D0.56)
Hence, A B
Group 1 0.25 0.75
Group 2 0.44 0.56
Turn 7/10 into decimal. (0.7)
Keep adding by 0.7 until you get the number closest to 4.1
3.5 is the closest, if we add another 0.7, we get 4.2.
So, he can get 5 sections of 0.7m
Answer:(3x-7) (3x-7)
Step-by-step explanation:
9x2-42x+49
The two by the 9 is power of 2 so the small two above
17. It would be about 155
