$\huge\text{Hey there!}$

$\huge\textbf{What does \boxed{median} mean in math?}}$

$\boxed{\text{Median}}\rightarrow\textsf{ is the number in the middle.}$

$\huge\textbf{How do you find the \boxed{median}?}$

$\text{You can found it by putting the numbers from \bf least to greatest.}$

$\huge\textbf{Question reads....}$

$\text{Find the median for the scores 91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95,}\\\text{72, 75}$

$\huge\textbf{Equation:}$

$\text{91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95, 72, 75}$

$\huge\textbf{Rearrange the problems to:}$

$\text{69,71,71,71,72,74,75,82,87, 89,89,91,95,95}$

$\huge\textbf{The expression:}$

$\mathsf{\dfrac{75 + 82}{2} = median}$

$\huge\textbf{Simplify it:}$

$\mathsf{\dfrac{75 + 82}{2} = median}$

$\mathsf{\dfrac{157}{2} = median}$

$\mathsf{257\div2 = median}$

$\mathsf{78.5 = median}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{78.5}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$

If rx – st = r, which expression represents r.

statuscvo [17]

Answer:

${ \tt{rx - st = r}}$

» Collect like terms, r terms on the left hand side by subtracting r from both sides and adding st to both sides

${ \tt{(rx - st) { \green{ - r + st }} = r{ \green{ - r + st}}}} \\ { \tt{rx - r = st}}$

» On the left hand side, factorise out r

${ \tt{ \green{r(x - 1)} = st}} \\ \\ { \boxed{ \tt{ \blue{ \: r = \frac{st}{x - 1} }}}}$
