Answer:
D
Step-by-step explanation:
We need to find the missing value to make sure it averages out to 250.
So they will be 5 rounds of different scores.
Since we dealing with averages, we need to set up a
equalivent equation to 250. We would add up all our previous scores and try to find the new x score and divide it by 5 and set it equal to 250. So our equation will look like.
Let x represent of our next game.
[tex] \frac{236 + 274 + 246 + 236 + x}{5} = 250[/tex]
Multiply by 5 both sides
[tex]236 + 274 + 246 +236 + x = 1250[/tex]
[tex]992 + x = 1250[/tex]
[tex]x = 258[/tex]
d is the answer
