Answer:
Step-by-step explanation:
x =(10-√-800)/2=5-10i√ 2 = 5.0000-14.1421i
x =(10+√-800)/2=5+10i√ 2 = 5.0000+14.1421i
The three numbers are 6, 7 and 9
<u>Explanation:</u>
First of all exclude the numbers which aren't correct.
From the 4th data,We can conclude the digit 5, 2 and 3 are wrong.
Now,
- 147 - One digit is right but wrong placed
- 189 - One digit is right and placed correctly
- 964 - Two digits are correct but at wrong place
- 523 - All digits are wrong
- 286 - One digit is right but in the wrong place
We've to find the three digits :
From case 4: 5, 2 and 3 are wrong
So, remove 5, 2 and 3 from all the cases
The numbers are:
- 147 - One digit is right but wrong placed
- 189 - One digit is right and placed correctly
- 964 - Two digits are correct but at wrong place
- _86 - one digit is right but in the wrong place
From 1st and 3rd we can say that: 4 is present in both the case but wrongly placed.
Now the digits become:
- 1_7 - One digit is right but wrong placed
- 189 - One digit is right and placed correctly
- 96_ - Two digits are correct but at wrong place
- _86 - one digit is right but in the wrong place
From 3rd and 4th case we can say that: 9 and 6 are correct but wrongly placed, 8 is not the number and 6 is placed at first
So, the two numbers of a 3 digit number are 6 and 9
From 2nd, 3rd and 4th case, the position of 6 and 9 are:
6 _ 9
From 1st case, 7 is the digit but wrongly placed. So, the 3 digit number becomes:
6 7 9
Answer:
Step-by-step explanation:
Given
Number of service bays 
Time taken by each bay to finish one oil change 
Working capacity 
hours per day
Thus, in 
hours the total number of times one bay has changed the oil is equal to
If one service bay's capacity is equal to 
, capacity of two service bays is equal to
Thus, the design capacity is
Statements 1 and 4 are correct. Let me know if you need more of an explanation. :)
