Amultiple choice test consists of nine questions, each of which has three choices. each question has exactly one connect answer. how many ways are there to fill out the answer sheet so that eight answers are connect and one is incorrect? (assume that a choice is made for each question.)

There are 18 ways to fill out the answer sheet so that eight answers are correct and one is incorrect.

Step-by-step explanation:

Consider the provided information.

A multiple choice test consists of nine questions, each of which has three choices.

We need to find the number of ways so that eight answers are correct and one is incorrect.

There is only one correct answer and for incorrect answer we have only 2 choices because 1 choice is correct.

Thus the number of possible ways are:

(2×1×1×1×1×1×1×1×1)+(1×2×1×1×1×1×1×1×1)+(1×1×2×1×1×1×1×1×1)+(1×1×1×2×1×1×1×1×1)+(1×1×1×1×2×1×1×1×1)+(1×1×1×1×1×2×1×1×1)+(1×1×1×1×1×1×2×1×1)+(1×1×1×1×1×1×1×2×1)+(1×1×1×1×1×1×1×1×2) = 2+2+2+2+2+2+2+2+2 = 18

There are 18 ways to fill out the answer sheet so that eight answers are correct and one is incorrect.

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
