Answer:
The given statement is false.
Step-by-step explanation:
We are given the following statement:
"If a linear system has the same number of equations and variables, then it must have a unique solution."
The given statement is false because If a linear system has the same number of equations and variables, then it may have unique solution, no solution or infinitely many solution.
There could be three types of solution
- no solution,
- unique solution and
- infinitely many solutions,
depending on the augmented matrix and coefficient matrix of the linear system.
Answer:
Yes
Step-by-step explanation:
They get more accurate as they have more data, the more data the more accurate it would be.
To find the probability of landing on a triangle, you will want find the combined areas of the triangles and the total area of the square target.
Divide the area of the combined areas and the total area to find the probability of landing on a triangle.
A = 1/2bh
1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)
A = bh
26 x 26
A = 676 square inches
128/676 = 0.189
There is an approximate probability of 0.19 of hitting a triangle.
