In a situation where x is a nontrivial solution, then every entry in x should not be nonzero. Therefore, it's false.
<h3>What is a nontrivial solution?</h3>
A nontrivial solution simply means a system of equation where the determinant of the coefficient is zero. When x is a nontrivial solution of Ax = 0, then at least one entry should be nonzero.
The equation x= x2u + x3v, with x2 and x3 free (and neither u nor v a multiple of the other), describes a plane through the origin. This is true. Since they're free variables, the space span has dimensions and this spans through the origin.
The equation Ax = b is homogeneous if the zero vector is a solution. Since x = 0 is a solution. Therefore, Ax = b. Hence, b = 0.
The effect of adding p to a vector is to move the vector in a direction parallel to p. It should be noted that adding p to a vector moves it in a direction that's parallel.

Answer and Step-by-step explanation:
We are given:
A side length of 7
An angle of 30.
We will use trigonometric functions to solve for a.
We will use the sine trig function.
Multiply a by both sides, then divide by sin30 on both sides.
Now, use a calculator and do 7 divided by sin of 30.
We get <em><u>a</u></em> to be:
14
<u>a is equal to 14</u>

Step-by-step explanation:
An error was made, correlation values can't be greater than 1.00.
The strength of the linear association between two variables is quantified by the correlation coefficient. The correlation coefficient always takes a value between -1 and 1. The 1 represents the perfect positive correlation and -1 represents the perfect negative correlation whereas the 0 represents the no correlation between two variables.
So, if the value of the correlation coefficient between shoe size and IQ is r = +1.99 then,
Analysts in some fields do not consider a correlation significant until the value is at least 0.8. However, a correlation coefficient with an absolute value of 0.9 or greater indicates a very strong relationship. 2.
