Question

Answer 1

B. 56

Step-by-step explanation

The average temperature is the sum of all the temperatures of the week divided by the number of days the temperature was taken:

`65=(76+70+x+68+55)/(5)`

Solving for x:

`\begin{gathered} 65\cdot5=269+x \\ 325-269=x \\ x=56 \end{gathered}`

The temperature on Wednesday was 56 ºF
