Answer: D
Step-by-step explanation: yes, because with each simulation, as the number of trials increase, the experimental probability gets closer and closer to the theoretical probability of
1/4.

The most cited professional who uses geometry is the air traffic controller. This professional needs to calculate routes, distances and times traveled in order to avoid accumulation of aircraft at the time of landing, for example.
Here is your answer
A. (4,-7)
REASON:
In quadrant IV abscissa is +ve and ordinate is -ve. Since absolute value is 11
Here |4|+|-7|= 4+7= 11

Answer:
x = -3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do t one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
Isolate the x. First, add 9 and subtract 4x from both sides:
6x (-4x) - 9 (+9) = 4x (-4x) - 15 (+9)
6x - 4x = -15 + 9
Combine like terms:
6x - 4x = -15 + 9
2x = -6
Next, divide 2 from both sides of the equation:
(2x)/2 = (-6)/2
x = -6/2
x = -3
x = -3 is your answer.

Important things to note:
- PEMDAS is the order of operation, and equals Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction.
- If there is an equal sign and the same variable on both sides, you are trying to isolate that variable.
- Remember to follow the division rule. If you are dividing two negative numbers, your answer will be positive. If you are multiplying two negative numbers, your answer will be positive. If you are dividing or multiplying one positive and one negative number, your answer will be negative.
