In order to increase typing speed Minisoft has redesigned its keyboard and provided a chime that is related to typing speed. The company wants to know if its innovations affect typing speed. Identify the independent and dependent variables in this proposed study. Group of answer choices The dependent variable is keyboard design; the independent variables are the speed of typing and the chime. The dependent variable is the number of errors made; the independent variables are the chime and the speed of typing. The dependent variable is the chime; the independent variables are the chime and typing speed. The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.

The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.

Step-by-step explanation:

The variable which we intend to measure or determine is called the dependent or predicted variable. However, to predict or measure the dependent variable, one or more variables are required, these are the variables whose different values or input affects the outcome of the dependent variable, these variables are called the independent variable.

In the scenario described above, the dependent variable is typing speed as it is the variable we intend to measure or determine using the new keyboard design and chime as the predictor variables.

the correct answer is 45x

9×5=45 then add the x
