A certain three cylinder combination lock has 70 numbers on it. To open it you turn to a number on the first cylinder then to a second number on the second cylinder and then to a third number on the third cylinder and so on until three number lock combination has been affected. Repetition are allowed and any of the 70 numbers can be used at each step to form the combination A) how many different lock combinations are there? B) what is the probability of guessing a lock combination on the first try? A) 343000
B) The probability that the correct lock combination is guessed on the first try is:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

the aswere is the one with all 8's and the second one is with the 10,8 and 6
