Answer :
9
Explanation :
The expression above signifies the Permutation expression
Permutation expression is given as nPr
The Permutation expression is calculated as:
nPr = P(n, r) = n! / (n - r)!
It the above question, we were asked to evaluate the expression 9P1
From the above question, we can see that:
n = 9 and r = 1
Therefore, the expression
9P1 = 9! / ( 9 - 1) !
9P1 = 9! / 8!
= 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 / 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 362880 /40320
= 9
Therefore, the evaluation of the expression 9P1 = 9
Answer:
8
Step-by-step explanation:
In this problem, you are dividing a positive by a positive, meaning the answer will also be positive.
16 ÷ 2 = 8
You can check your answer by multiplying:
8 × 2 = 16
Answer:
1. 1 13/24
2. 5/12
Step-by-step explanation:
2/3 = 16/24
7/8 = 21/24
Add.
16/24 + 21/24 = 37/24
As a mixed number, this is 1 13/24.
3/4 = 9/12
1/3 = 4/12
Subtract.
9/12 - 4/12 = 5/12
Hope this helps!
