Answer: It is B and C.
Step-by-step explanation:
If you divde the -4 and -5 for choice B, it will become 4/5 since it's an absolute value.
For Choice C, it's also the same but before the fractions were negative and there is a negative sign which means it's also the aboslute value which is 4/5.
Hope this helps! <3
<em>r</em> should be 4/7. You're comparing the given series to a geometric series that converges. By the limit comparison test, you have
![\displaystyle\lim_{n\to\infty}\frac{\frac{4^n+7}{7^n}}{\frac{4^n}{7^n}}=\lim_{n\to\infty}\frac{4^n+7}{4^n}=\lim_{n\to\infty}\left(1+\frac7{4^n}\right)=1](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bn%5Cto%5Cinfty%7D%5Cfrac%7B%5Cfrac%7B4%5En%2B7%7D%7B7%5En%7D%7D%7B%5Cfrac%7B4%5En%7D%7B7%5En%7D%7D%3D%5Clim_%7Bn%5Cto%5Cinfty%7D%5Cfrac%7B4%5En%2B7%7D%7B4%5En%7D%3D%5Clim_%7Bn%5Cto%5Cinfty%7D%5Cleft%281%2B%5Cfrac7%7B4%5En%7D%5Cright%29%3D1)
and since this limit is positive and finite, and the series you're comparing to is convergent, then the first series must also be convergent.
The 1st number is odd, less than 5, so it might be 1 or 3, the probability is 2/10
But if the sum has to less than 5, than *when 1st number is 1, the second number can only be 1.2.3
and *when 1st number is 3, 2nd can only be 1
*1: 3/100
*2: 1/100
3/100+1/100=4/100
so the answer should be (4/100)/(2/10)=2/10=1/5
I'm not so sure if I'm right
