Answer:
Option B
Step-by-step explanation:
To solve these kind of question we just simply keep on inserting the values of x and if we get the required value of y that is in the table that equation is our answer, For example lets take Option A,
y = 8x
If we insert x = 0 we get,
y = 8(0)
y=0
but in the table it says we get 14 so option A is incorrect
Like this we keep checking for more values and all the values of x satisfy our equation in Option B like this,
![y=8x+14\\y=8(0)+14\\y= 14\\\\y=8x+14\\y=8(1)+14\\y=8+14\\y=22\\\\y=8x+14\\y=8(2)+14\\y=16+14\\y=30\\](https://tex.z-dn.net/?f=y%3D8x%2B14%5C%5Cy%3D8%280%29%2B14%5C%5Cy%3D%2014%5C%5C%5C%5Cy%3D8x%2B14%5C%5Cy%3D8%281%29%2B14%5C%5Cy%3D8%2B14%5C%5Cy%3D22%5C%5C%5C%5Cy%3D8x%2B14%5C%5Cy%3D8%282%29%2B14%5C%5Cy%3D16%2B14%5C%5Cy%3D30%5C%5C)
and so on so Option B is the answer
Answer:
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.
