Answer:
C
Step-by-step explanation:
Answer: 3/4w
Explanation:
1/2(w-6)+1/4(w+12)
= 1/2w-6/3 + 1/4w+12/4
= 1/2w-3 + 1/4w+12/4
= 1/2w +1/4w
= 2/2(1/2)w + 1/4w
= 2/4w+1/4w
=3/4w
Simplify the following:
(6^5/7^3)^2
7^3 = 7×7^2:
(6^5/(7×7^2))^2
7^2 = 49:
(6^5/(7×49))^2
7×49 = 343:
(6^5/343)^2
6^5 = 6×6^4 = 6 (6^2)^2:
((6 (6^2)^2)/343)^2
6^2 = 36:
((6×36^2)/343)^2

Answer: 60466176/117649
Y - 5 = 2( x - 1 ) <=>
y - 5 = 2x - 2 <=.
2x - y + 3 = 0.
Since there are 5 choices and there are 10 possible digits for each digit of the PIN( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
The total value possible 5 pins are 10⁵ = 100000
Using permutation, since 5 numbers are selected without repetition:
The probability that no numbers are repeated is= 30240/ 100000
≈ 0.302
