D?

$$\large \frac{ t_1 + t_2 + t_3 + t_4 + t_5 }{ 5 } = \text{average}$$

anonymous · Answer

how did u get the answer

calculusxy · Answer

$\large t_1$ to $\large t_4$ are values that you can replace with 77, 71, 77, and 67. Since we are trying to find $t_5$, we can leave it as it is. I put the equation over 5 because we will be taking the average of 5 games. And for the part that says "average" we can replace it with 74.

calculusxy · Answer

$$\large \frac{ 77 + 71 + 77 + 67 + t_5 }{ 5 } = 74$$
Do you know how to solve this?

calculusxy · Answer

Meaning solve for $\large t_5$?
