nCp = n! / (p!)*(n-p)!
so 12C8 = 12! / (8!)*(4!)
= 11880 / 24
= 495
ans is C
Answer: Answer C , Only student 2, because dilation preserve angle measures and side lengths are proportional
So you have set of these 6 numbers
And we know that we have 3 even numbers (2, 4, 6) and 3 odd numbers (1, 3, 5).
Now the possibility you will throw even number is 50%
12z^2 - 7z -12/ 3z^2 + 2z - 8
= (4z+3) (3z -4)/ (z+2)(3z -4)
= (4z + 3) / (x+2)
Hope this helps
Answer:
1/2 km
Step-by-step explanation:
3/10 + 1/5, find common denominators
3/10 + 2/10 = 5/10, simplify
1/2 km
