Answer:
Step-by-step explanation: For example, if we have matrix A whose all elements in the first column are zero. Then, by one of the property of determinants, we can say that its determinant is equal to zero. Hence, A would be called as singular matrix. Note that singular matrices are non-invertible (their inverse does not exist).
Answer:
It is the experimental condition.
Step-by-step explanation:
In the experiment given in the question, the amount of sleep is the independent variable and the number of photographs they remember is the dependent variable because it depends on the amount of sleep.
The 8 hours of sleep, which creates the difference in the experiment between the control group and the test group, is the experimental condition.
The experimental condition is the variable that is changed to let the researcher observe the effects on the dependent variable.
