Answer: The SST for the data set is 8.
Step-by-step explanation:
Since we have given that
Coefficient of determination (R²) = 0.25
SSE for the data = 6
SST = ?
As we know the formula for coefficient of determination:

Hence, the SST for the data set is 8.

Answer:
Step-by-step explanation:
The total amount of punch that Jennifer made for her party is 5 Liters. Her brother made another 750 milliliters.
1000 milliliters = 1 liter
750 milliliters = 750/1000 = 0.75Liter
if they combine the two batches, the total amount made would be
5 + 0.75 = 5.75Liter
= 5.75 × 1000 = 5750 milliliters
The number of 180 milliliters servings would be
5750/180 = 31 servings
There would be leftovers of 170 milliliters
