The answer would be 8*2. Or 8 and the exponent would be 2.
Solution:
Fabric possessed by Da. Shari = 4 Sweaters + 2 Coats + 5 Jackets= 11 in all
Arrangement that Da Shari wants to arrange 4 Sweaters + 2 Coats + 5 Jackets is to put "a sweater first and a jacket last".
After putting a sweater first and jacket last , total fabric which needs to be arranged is (3 Sweaters + 2 Coats + 4 Jackets)=9 in all.
Total number of possible arrangement = (1 sweater) × [9 fabric=(3 Sweaters + 2 Coats + 4 Jackets) arrangement] × (1 Jackets)
= 1! × 9 ! × 1!
= 9 !
= 9 × 8 × 7× 6× 5× 4× 3×2×1
= 362,880 ways
Answer:
x = 25
Step-by-step explanation:
0 = 2x - 50
0 - 2x = -50
-2x = -50
x = 25
Answer:
A≈46.4
Step-by-step explanation:
Since the order does not matter as the colors of the scarves are picked, this is a case of combinations. We use the formula:
nCk = n!/( (n-k)! k! )
14C4 = 14!/( (14-4)! 4! )
14C4 = 1001
Therefore, there are 1001 different combinations possible if 4 scarves are picked from a box containing 14 scarves of unique colors.
