Answer:
Step-by-step explanation:
A box contains four cards: One card is black on both sides, one card is red on both sides and two cards are black on one side and red on the other side. One card is selected at random and you can see only one side.i) If the side you see is black, what is the probability that the other side is black?ii) If the side you see is black, what is the probability that the other side is red?
Given that:
Number of cards = 4
x = Black on both sides = 1
y = Red on both sides = 1
z = Black on one side, red on one side = 2
.i) If the side you see is black, what is the probability that the other side is black = b
Probability of black 
P(x) = 1/4 ; p(b|x) = 1 
P(y) = 1/4 ; p(y|x) = 
 
        
             
        
        
        
Answer:
A
Step-by-step explanation:
So we have the equation: 

First, let's subtract 16 from both sides: 

Now, let's divide both sides by 3: 

Remember that with fractional exponents, we can move the denominator into the root position. Therefore: 
![(\sqrt[3]{x-4})^4=16](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx-4%7D%29%5E4%3D16)
Let's take the fourth root of both sides. Since we're taking an even root, make sure to have the plus-minus symbol!
![\sqrt[3]{x-4} =\pm 2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx-4%7D%20%3D%5Cpm%202)
Cube both sides. Since we're cubing, the plus-minus stays. 

Add 4 to both sides. 

Calculator: 

So, our answer is A. 
And we're done!

Answer:
__
12 x 4 x 7 + 1
__
Step-by-step explanation:
The biggest number can be made by multiplying all the numbers. However, since one of these numbers is 1, multiplying 1 by all those others won’t do anything. So to get the biggest number you would multiply 12 by 4 by 7 and add 1. 
 
        
             
        
        
        
122/11....u divide 122 by 11...or how many times does 11 go into 122.
122/11 = 11.09 with a line over the 09 because it is repeating
