Decide whether you would use a permutation, a combination, or neither. Next, write the solution using permutation notation or co
mbination notation, if possible, and, finally, answer the question. How many different arrangements are there of the letters in the word CORRECT?
1 answer:
Answer:
Permutation is used.
No. of arrangements = 1260
Step-by-step explanation:
Permutation is used for choosing & arrangement of 'r' out of 'n' objects, when sequence is important.
Total no. of alphabets in CORRECT = 7
C is repeated twice, R is repeated twice
So, Total No. of arrangements = <u>7 !</u>
(2!)(2!)
= 5040 / 4
= 1260

Answer:
3^2 + x^2 = 9^2
9 + x^2 = 81
x^2 = 72
x = 
, which is about 8.5
Cosine X = 3/9
Cosine X = 1/3
angle x= 70.5
If angle x= 70.5, angle z = 19.5 degrees.
