Answer:
If I get 0=0 then it means:
- If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutions
- If the system of equations is 3 linear equations in 3 variables, there might be infinite number of solutions
Step-by-step explanation:
Linear equation systems can consist of two or three equations with two or three unknowns respectively.
A system of linear equations in two variables has infinite solutions when the lines made by them overlap each other and similarly a system with three variables has infinite solutions when two lines overlap each other and third plane is parallel to them
Hence,
If I get 0=0 then it means:
- If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutions
- If the system of equations is 3 linear equations in 3 variables, there might be infinite number of solutions
I'm really sorry, but I only know the first question.
The answer is 340.
Answer:
Less than 264.44 days would be for the shortest 20%
Step-by-step explanation:
Given that X, the length of a human pregnancy is normally distributed with a mean of 272 days with a standard deviation of 9 days (Bhat & Kushtagi, 2006).
X is N(272, 9)
Corresponding Z score would be for any x
We have to find out the shortest 20%
Corresponding z score i.e. z score 20th percentile is given by
-0.84
corresponding x score is
Less than 264.44 days would be for the shortest 20%
