Answer: 60 and 80
Step-by-step explanation: Start off with the highest number, which is 10. The numbers between 49 and 95 that can be divided by 10 are 50, 60, 70, 80, and 90. Next, figure out what can be divided by 5. All of them can. Next, find out what numbers can be divided by 4. 50, 70, and 90 can’t because they would end up as a decimals. 60 and 80 can be divided by 4, 5, and 10.
Answer: The relative frequency of column A in group 1=![0.75](https://tex.z-dn.net/?f=0.75)
The relative frequency of column B in group 1=![0.25](https://tex.z-dn.net/?f=0.25)
The relative frequency of column A in group 2=![0.56](https://tex.z-dn.net/?f=0.56)
The relative frequency of column B in group 2=![0.44](https://tex.z-dn.net/?f=0.44)
Step-by-step explanation:
The relative frequency is the ration of each frequency by the total value in particular group.
For group 1 : Total =102+34=136
The relative frequency of column A in group 1=![\frac{102}{136}=0.75](https://tex.z-dn.net/?f=%5Cfrac%7B102%7D%7B136%7D%3D0.75)
The relative frequency of column B in group 1=![\frac{34}{136}=0.25](https://tex.z-dn.net/?f=%5Cfrac%7B34%7D%7B136%7D%3D0.25)
For group 2 : Total =18+14=32
The relative frequency of column A in group 2=![\frac{18}{32}=0.5625\approx0.56](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B32%7D%3D0.5625%5Capprox0.56)
The relative frequency of column B in group 2=![\frac{18}{32}=0.4375\approx0.44](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B32%7D%3D0.4375%5Capprox0.44)
Answer:
a < ![\frac{31}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B31%7D%7B2%7D)
Step-by-step explanation:
Given
a - 15 > - 40 - 6 + 3a ← simplify right side
a - 15 > - 46 + 3a ( subtract a from both sides )
- 15 > - 46 + 2a ( add 46 to both sides )
31 > 2a ( divide both sides by 2 )
> a ⇒ a < ![\frac{31}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B31%7D%7B2%7D)
Answer:
3*104=312
15*108=1620
1620/312=5.19230769 OR 5.19 OR 5.1 OR 5
