When collecting like terms you are adding or subtracting 2 "things" that have the same variable (letter).
<span>E[Y] = 0.4·1 + 0.3·2 + 0.2·3 + 0.1·4 = 2
E[1/Y] =0.4·1/1 + 0.3·1/2 + 0.2·1/3 + 0.1·1/4 = 0.4 + 0.15 + 0.0666 + 0.025?0.64
V[Y] =E[Y2]-E[Y]2= (0.4)·12+(0.3)·22+(0.2)·32+(0.1)·42-22= 0.4+1.2+1.8+1.6-4= 5-4 = 1</span>
Answer:
54/7
Step-by-step explanation:
- Use the KCF method - Keep, Change, Flip
- 6 divided by 7/9 is just 6/1 divided by 7/9
- You can keep 6/1 as the way it is
- Next, you change the sign from division to multiplication
- Lastly, you flip 7/9 to 9/7
- It will now change from 6 divided by 7/9 to 6/1 x 9/7
- You now multiple 9 x 6 which is 54 and divide by 7
- You cannot simplify further so the answer is 54/7
