Answer:
2
Step-by-step explanation:
We are given that a decimal number d
d=0.12345678...
Where d is formed by writing in succession all the positive integers in increasing order after decimal point.
We have to find the 100th digit of d to the right of the decimal point.
Place of first digit 1 after decimal=Tenth
Place of second digit 2 after decimal=Hundredth
Place of third digit 3 after decimal=Thousandth
Therefore, 100th digit of d to the right of the decimal point=2
Domain: E. the set of allowable x-values, or inputs, of an equation
Solution: C. output values of an experiment or situation
Independent Variable: F. a value that can be controlled or that affects the other variable.
Dependent Variable: I am not so sure about this one, but I would go with A. <span>an ordered pair (x, y) that when substituted into a two-variable equation makes the equation true.</span>
