Basically
18(2)=36 and 12(2) is 24 and they add up to 60. So yes
The correct answer is option a.
<span>6.16 x 10^6 = 6,160,000
</span>10^6 = 1000000
6.16 = 616/100
616/100 x 1000000 =6160000
So, the standard form of 6.16 x 10^6 is 6,160,000
Answer:
There are 210 ways
Step-by-step explanation:
The number of ways or combinations in which we can select x elements from a group of n elements where the order doesn't matter can be calculated as:
![nCx=\frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=nCx%3D%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
So, we have 10 teaching assistants and we need to choose 4 (one assistant per question) to grade each question. It means that n is equal to 10 and x is equal to 4.
Therefore, the number of ways that the assistants can be chosen to grade the exam are calculated as:
![10C4=\frac{10!}{4!(10-4)!}=210](https://tex.z-dn.net/?f=10C4%3D%5Cfrac%7B10%21%7D%7B4%21%2810-4%29%21%7D%3D210)
