Answer:

9/64

Step-by-step explanation:

Given,

White balls  = 5

Black Balls = 3

Total Balls = 5 + 3 = 8 balls

P (1st black ball) = 3/8

If there is replacement, P (2nd black ball) = 3/8

P (Both balls are black)

= P (1st black ball) x P(2nd black ball)

= 3/8 x 3/8

= 9/64

Which statement best describes Marcos equation
satela [25.4K]
Marco's equation is correct.  Cosine is an even function, which means that for every x, f(-x) = f(x).  In other words, you get the same answer for a negative value that you would for its corresponding positive value.

UNO [17]

Answer:

Step-by-step explanation:

The viniculum in a fraction represents subtraction with exponents.

Subtracting exponents gives us  3^12/3^8 * 3^2

Simplifying gives 3^12/3^10. Then, we can achieve 3^12 - 3^10.

This equals 3^2.

3^2 = 9.

So 9 is the answer of your question.
