Answer:
x = -2
Step-by-step explanation:
To solve, we need to <u>isolate "x"</u> by moving other numbers to the right side of the equal sign. To "move" a number, <u>do the reverse operation to both sides of the equation</u>. <u>Move numbers in reverse BEDMAS order</u>.
4(-2x - 1) = 12 Do the opposite of times 4
Divide both sides by 4
-2x - 1 = 3 Do the opposite of subtract 1
Add 1 to both sides
-2x = 4 Do the opposite of times -2
Divide both sides by -2
x = -2 Solved for "x"

Answer:
The experimental probability is larger than the theoretical probability.
Step-by-step explanation:
On a six-sided number cube labeled 1 through 6, there are 3 odd numbers and a total of 6 numbers. The chance of rolling an odd number is 3/6, or 1/2.
The theoretical probability would be 1/2.
After rolling the cubs 500 times, an odd number is rolled 325 times. This means that 325/500, or 13/20, of the time, an odd number is rolled.
The experimental probability would be 13/20.
1/2 can be rewritten as 10/20.
13/20 > 10/20
Since 13/20 is greater than 10/20, the experimental probability is larger than the theoretical probability.
The experimental probability is larger than the theoretical probability.
I hope this helps. :)
