Answer:
Step-by-step explanation:
given are four statements and we have to find whether true or false.
.1 If two matrices are equivalent, then one can be transformed into the other with a sequence of elementary row operations.
True
2.Different sequences of row operations can lead to different echelon forms for the same matrix.
True in whatever way we do the reduced form would be equivalent matrices
3.Different sequences of row operations can lead to different reduced echelon forms for the same matrix.
False the resulting matrices would be equivalent.
4.If a linear system has four equations and seven variables, then it must have infinitely many solutions.
True, because variables are more than equations. So parametric solutions infinite only is possible
Answer:
1
Step-by-step explanation:
list the numbers that are odd or greater than 2
1,2,3,4,5,6
aka every single outcome
therefore the answer is just 1

Answer:
Step-by-step explanation:
Since we want to find <em>x</em> and we are given the hypotenuse and the side adjacent to <em>x</em>, we can use the cosine ratio:
The adjacent side is 18 and the hypotenuse is 35. Substitute:
Take the inverse cosine both sides. Use a calculator (make sure you're in Degrees mode!). Hence:
