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.
Divide 3 by 2 and you should get 1.5
4 and 5. The square root of 16 is 4 , the square root of 25 is 5. Those two numbers are the closest to 18.
Just take n=1,2,3,4,5 respectively to find out the first 5 terms.
First 5 terms = 4,3,2.25,1.69 respectively.
For the 5th partial sum, just add the first 5 terms.
5th partial sum = 10.34
....
First 4 terms : 5,8,11,14 respectively.
Now you need to find the other next 4 terms to find out the 8th partial sum.
17,20,23,26
8th partial sum = 124
Hope this helps:)
