Janie flips a coin 70 times and records if it comes up heads. if getting heads is a success, what is the probability of a failure? 0.2 0.5 0.7 1.00

          The probability of failure is:

                         0.5

It is given that:

Janie flips a coin 70 times and records if it comes up heads.

Also, getting of a head is considered as a success.

This means that getting a tail will be a failure for the experiment.

As we know that for a unbiased coin the probability of getting a tail; and a head are equal.

Hence, the probability of head is: 1/2=0.5

and probability of tail is:   1/2=0.5

           Hence, the probability of a failure is: 0.5

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
