Answer:

1. Re-writing an equation to remove all the variables.

Step-by-step explanation:

Backtracking is the procedure required for solving problems that has series of parts combined as one. It involves the retracing each part after one or two parts has been solved to solve the whole problem.

In mathematics when given an equation with variables, the solution can be obtained by calculating the values of each variable. To determine the final solution sometimes requires substitution procedure.

The best option that describe backtracking in maths-sense is; re-writing an equation to remove all the variables.

Answer: Our required probability is 0.65.

Step-by-step explanation:

Since we have given that

                      18-20                  Not 18-20           Total

Male                0.23                    0.35                 0.58

Female            0.16                     0.26                0.42

Total                0.39                    0.61                   1

P(female or between 18-20) = P(female) + P(18-20) - P(Female and 18-20)

P(female or between 18-20) =  0.42+0.39-0.16

P(female or between 18-20) = 0.65

Hence, our required probability is 0.65.

If f(x)=7x what is the inverse of f(x)
Brums [2.3K]

Answer:

f(x)=x/7

Step-by-step explanation:

f(x)=7x

y=7x

x=7y (switch y and x for inverse)

x=7y (isolate y)

x/7=y

The inverse of f(x)=7x is f(x)=x/7
