-28n - 4 + 2n - 8 = 66

-26n - 12 = 66

-26n = 78

n = -3

66 = -4(7n + 1) + 2(n - 4)

  • Distribute -4 inside the parentheses.

66 = -28n - 4 + 2(n - 4)

  • Distribute 2 inside the parentheses.

66 = -28n - 4 + 2n - 8

  • Combine like terms.

66 = -26n - 12

  • Add 12 to both sides.

78 = -26n

  • Divide both sides by -26.

n = -3

A bicycle lock has a four-digit code. The possible digits, 0 What is the probability that the lock code will begin with
nika2105 [10]

Answer:

0.1-0.6

Step-by-step explanation:

First let's find the number of the elements in the sample space, that is the total number of codes that can be produced.

The first digit is any of {0, 1, 2...,9}, that is 10 possibilities

the second digit is any of the remaining 9, after having picked one. 

and so on...

so in total there are 10*9*8*7 = 5040 codes.

a. What is the probability that the lock code will begin with 5?

Lets fix the first number as 5. Then there are 9 possibilities for the second digit, 8 for the third on and 7 for the last digit.

Thus, there are 1*9*8*7=504 codes which start with 5.

so 

P(first digit is five)=

b. What is the probability that the lock code will not contain the number 0? 

from the set {0, 1, 2...., } we exclude 0, and we are left with {1, 2, ...9}

from which we can form in total 9*8*7*6 codes which do not contain 0.

P(codes without 0)=n(codes without 0)/n(all codes)=(9*8*7*6)/(10*9*8*7)=6/10=0.6

Answer:

0.1 ; 0.6
