Answer:
279,936
Step-by-step explanation:
Since there are 6 options for every digit, and seven digits
So,
6^7=279,936
The total number of distinct combinations for making 7 digits lock is 2,79,936.
What is permutation?A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
Formula for permutation with repetition:[tex]nP_{r} =n^{r}[/tex]
Where,
P is the total number of combinations.
n is the total number of items in a set
r is the total number of items to be selected from the set
According to the given question.
We have to form a lock that has 7 digits by using numbers from 0 to 5.
⇒ Total numbers of items in a set = 6
and total number of items to be selected = 7
Since, we have to form a lock of 7digits but we have only 6 digits. So we have to repeat this numbers so that we can form a 7 digit lock.
Therefore, the total number of combinations for making 7 digits lock is given by
[tex]6P_{7} = 6^{7}[/tex]
⇒[tex]6^{7}=2,79,936[/tex]
Hence, the total number of distinct combinations for making 7 digits lock is 2,79,936.

A guitar factory has a cost of production C(x)=75x+50000. If the company needs to break even after 150 units sold, at what price should they sell each guitar?
The price of each guitar would be; 666.7 rounded to the nearest greatest cent.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that guitar factory has a cost of production C(x)=75x+50000. If the company needs to break even after 150 units sold, then;
C(x)=75x+50000
75x + 50000 = 150x
C(x)= 50000 = 75x
x = 50000/75
x = 666.67
Therefore, The price of the each guitar would be; 666.7 rounded to the nearest greatest cent.

R and T are two mutually exclusive events.
P(R) = 0.2 and P(R or 1) = 0.69
Work out P(not T).
Answer:
P(not T ) = 0.51
Step-by-step explanation:
Step(i):-
Given that the R and T are two mutually exclusive events
P(R∩T) = 0
Addition theorem on probability
P(RUT) =P(R)+P(T) - P(R∩T)
P(RUT) =P(R)+P(T) - 0
P(RUT) =P(R)+P(T)
Step(ii):-
Given P(R) = 0.2 and P(RUT) = 0.69
P(RUT) =P(R)+P(T)
P(T) = P(RUT) -P(R) = 0.69 -0.2
P(T) = 0.49
P(not T) = 1- P(T)
P(not T ) = 1 - 0.49 = 0.51
Final answer:-
P(not T ) = 0.51
