Answer:
3^7 * 3^(-4) = 3^(7 - 4) = 3^3 = 27
The answer is yes. I think that I’m right
Answer:
9/11
Step-by-step explanation:
12/11k÷4/3k
Copy dot flip
12/11k* 3k/4
36k / 44k
Divide the top and bottom by 4k
9/11
Step-by-step explanation:
S = { 1, 2, 3, 4, 5, 6 7, 8 }
n ( S ) = 8
Let A be the event of getting 4,
A = { 4 }
n ( A ) = 1
P ( A )
= n ( A ) / n ( S )
= 1 / 8
Therefore, the probability of spinning a 4 is 1 / 8.
S = { A, B, A, C, A, B }
n ( S ) = 6
Let Y be the event of getting C,
Y = { C }
n ( Y ) = 1
P ( Y )
= n ( Y ) / n ( S )
= 1 / 6
Therefore, the probability of spinning a C is 1 / 6.
