Answer:
5x - 4 = 11
1/2x + 15 = 9
Step-by-step explanation:
I dont exactly know how u would show work.
If it says something is less than a number, then it will be at the back of the equation. So skip that part and u will see it says five times a number. The number is unknown therefore it will a variable (i chose x to be the variable). 5 times x is 5x. Minus the 4 would be 5x - 4. Then it says the equation equals 11. So 5x - 4 = 11.
If it says something is more than a number, it can be on either side of the equation using the commutative property of addition. But if we want to consider it being like subtraction, then it also will be in the back of the equation. A half is one over two (1/2). A half of x is 1/2x. Plus the 15 would be 1/2x + 15. It then states that the equation equals 9. So 1/2x + 15 = 9.
Answer:
Theoretical probabilities are the long-run relative frequencies based on an experiment.
Step-by-step explanation:
Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.
With theoretical probability, you don't experiment. Instead, you use what you know about the situation to determine the probability of an event occurring.
Experimental probability approaches theoretical probability when the number of trials is extremely large.
Therefore, theoretical probabilities are the long-run relative frequencies based on an experiment.
