write ${\displaystyle 3\times 3\times 3\times 3}$ in exponential form.

Use Gaussian elimination to find the complete solution to the system of given equations, or show that none exists
$\{\begin{array}{l}5x+8y-6y=14\\ 3x+4y-2z=8\\ x+2y-2z=3\end{array}$

When solving systems of we have at least two unknowns. A common example of a system of equations is a mixture problem. If I know that the solution I use to clean my car windows is 65% water and 35% cleaner, I have one relationship. If I also know that I only have a 3-liter spray bottle that gives me a second relationship.
Finally, solve the system of equations

f. 6

Give an example of an event that is more likely than rolling a sum of 8

${\displaystyle A=p+prt}$ for t

If u is an algebraic expression and c is a positive number,
1. The solutions of $|u|<c$ are the numbers that satisfy$-c<u<c$.
2. The solutions of $|u|>c$ are the numbers that satisfy$u<-coru<c$.
These rules are valid if $<$ is replaced be ${\displaystyle \le }$ and $>$ is replaced by ${\displaystyle \ge }$

(There may be more than one correct answer) Logistic regression can be used for modeling the continuous response variable with dichotomous explanatory variable. Logistic regression can be used for modeling the dichotomous response variable with dichotomous explanatory variable Logistic regression can be used for modeling the continuous response variable with dichotomous or other type of categorical explanatory variables. Logistic regression can be used for modeling the dichotomous response variable with dichotomous and not for continuous explanatory variables. Logistic regression can be used for modeling the dichotomous response variable with categorical explanatory variables and/or continuous explanatory variables.
