Step-by-step explanation:

$mean \: ( \bar x) = \frac{2 + 3 + 4 + 5}{4} = \frac{14}{4} = 3.5 \\ \\ median \: = \frac{3 + 4 }{2} = \frac{7}{4} = 3.5 \\ \\$

Thus, mean and median are same.

54 divided by _____ = -27

Nikitich [7]

54/-2 = -27

First, let's rewrite:

Let x represent the unknown number:

$\frac{54}{x}=\text{ -27}$

$\begin{gathered} \frac{54}{x}\text{ = -27} \\ 54\text{ = -27x} \\ \text{Divide both sides by -27} \\ \frac{54}{-27}=\text{ }\frac{-27x}{-27} \end{gathered}$ $\begin{gathered} 27\times2\text{ = 54} \\ x\text{ = -2 (because we are dividing positive number by a negative number)} \\ So\text{ our answer will be negative} \end{gathered}$

Hence, 54/-2 = -27

Remark

Without being given choices, we can get answers but they may not be listed among your. The important think is to be working in the same units

Convert miles/hour to m/sec

$\frac{2.5 mi}{h}*\frac{1 h}{3600 sec}*\frac{1.6 km}{1 mi}*\frac{1000 m}{1 km}$
