Answer:
Secret Message: The dependent variable is what is"
Lock 8 key: MEASURED
Step-by-step explanation:
The letters on a telephone keypad can be used for text entry tasks.
To type a letter, find the corresponding number key and press it the correct number of times.
For example:
- To type an "S" press the 7 key four times: 7777 = S
- To type an "E" press the 3 key two times: 33 = E
Therefore, the secret message says:
- 8 44 33 = THE
- 3 33 7 33 66 3 33 66 8 = DEPENDENT
- 888 2 777 444 2 22 555 33 = VARIABLE
- 444 7777 = IS
- 9 44 2 8 = WHAT
- 444 7777 = IS
"The dependent variable is what is"
The dependent variable is what is ... being measured in an experiment or a mathematical equation.
Therefore, the lock 8 key is: MEASURED
