Answer:
two dice are thrown, so S = {(1,1); (1,2); (1,3); ...;(6,5); (6,6)} ---> 36
the sum is 2, 4, 6
sum = 2 --> (1,1) ---> 1
= 4 --> (1,3); (2;2); (3,1) ---> 3
= 6 --> (1,5); (2,4); (3,3); (4;2); (5,1) ---> 5
⇒
= 9/36 = 1/4
You need to first make everything positive:
x^2=36
Then you need to get the square root of each side:
x=6 or -6

Answer:
The answer is 
Step-by-step explanation:
when writing scientific notation, there must be one number to the left of the decimal point.
To achieve this in this problem, you need to move the decimal point 3 times to the right.
because you are moving the point to the right, the exponent will be negative.
*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*
therefore you answer should be written as:
