Step-by-step explanation:
I believe its b, because1.5 is 10 times 0.15
and 6.3 is 10 times 0.63
Like 8÷48 or 6÷48? like that

Is that the whole question?
Answer:
1830
Step-by-step explanation:
Sum of smallest 30 positive even numbers is given by
2 + 4 + 6 + 8 + ......... up to 30 terms
= 2 ( 1 + 2 + 3 + 4 + ....... + 30)
= 
Again the sum of largest 30 odd negative numbers is given by
- 1 - 3 - 5 - 7 - ...... up to 30 terms.
= - (1 + 3 + 5 + 7 + ...... up to 30 terms)
{This is an A.P. series having first term 1, common difference 2 and the number of terms 30}
= ![-\frac{30}{2} [2 \times 1 + (30-1) \times 2]](https://tex.z-dn.net/?f=-%5Cfrac%7B30%7D%7B2%7D%20%5B2%20%5Ctimes%201%20%2B%20%2830-1%29%20%5Ctimes%202%5D)
= - 900
Now, Winnie has the sum 930 and Grogg has the sum - 900.
So, Winnie's sum is (930 + 900) = 1830 more than Grogg's sum. (Answer)
Answer:
If the positions are distinct, as in executive offices, then P(9,5)
P(9,5) = 9!/(9 - 5)! = 15120..... is the answer
But...
If the positions are equivalent, such as seats in a legislative body, then C(9,5)
C(9,5) = 9!/[(9 - 5)!(5!)] = 126
Hope this can help you :)
