Answer:

[tex] y= 56[/tex]

Step-by-step explanation:

[tex] \frac{44 + 47 + y + 58 + 55}{5} = 52[/tex]

[tex] \frac{204 + y}{5} = 52[/tex]

[tex]204 + y = 260[/tex]

[tex]y = 56[/tex]

Answer:

y = 56

Step-by-step explanation:

The average is calculated as

average = [tex]\frac{total}{count}[/tex]

Given the average of 5 is 52, then

[tex]\frac{44+47+y+58+55}{5}[/tex] = 52, that is

[tex]\frac{204+y}{5}[/tex] = 52 ( multiply both sides by 5 )

204 + y = 260 ( subtract 204 from both sides )

y = 56
