Answer:
(x + y)^5.
Step-by-step explanation:
The (r+1)th term of (x + y)^n = nCr x^n-r y^r
Compare this with 10x^3 y^2 we get
nCr = 10 , n-r = 3 and r = 2 giving n = 3+2 = 5
5C2 = 10.
So the answer is (x + y)^5.
Answer:
Yes
Step-by-step explanation:
Permutation :
nPr = n! ÷ (n - r)!
nCr = n! ÷ (n-r)!r!
11 objects taken 3 at a time :
11P3 = 11! ÷ (11 - 3)!
11P3 = 11! / 8!
11P3 = (11 * 10 * 9 )
11P3 = 990
Dividing by 3!
3! = 3*2*1 = 6
= 990 / 6
= 165
For combination :
11C3 = 11! ÷ 8!3!
11C3 = (11 * 10 * 9) / (3 * 2 * 1)
11C3 = 990 / 6
11C3
You are trying to find the probability of a blue candy not containing nuts.
So since we're only looking at the blue, forget about every other row except that one.
So in total, there are 50 blue candies.
Without nuts, there are 20 blue candies.
20/50 = 0.4
Then move the decimal two points to the left to get your percentage.
The answer is:
B. 40%
00.5 i think or its 0.5 i hope im right have a good day! :) Bye
3/4 serving = 1/3 cup
1 serving = 1/3 / 3/4 = 4/9
Therefore, unit rate = 4/9 cup per serving.
