1) The population
Is the set of all the terms that the teacher taught this semester and which he wrote down on the note cards and put in the paper bag.
2) The sample is every set of five cards that is selected by each student.
3) I think the sample is representative because all ther terms have the same probability of being selected.
Further, given that the cards are replaced every time all the students will face the same population when they are going to select a sample.

Answer:
the volume at 606k is 2.22....the third one
Step-by-step explanation:
v1=1.00 t1=273 v2=? t2=606
v1/t1=v2/t2
1.00/273=v2/606
1.00×606=273v2
606=273v2
606/273=v2
2.21 L=v2
Answer:
x=−15+√10 or x=−15−√10
Step-by-step explanation:
Let's solve your equation step-by-step.
(x+15)2−10=0
Step 1: Simplify both sides of the equation.
x2+30x+215=0
For this equation: a=1, b=30, c=215
1x2+30x+215=0
Step 2: Use quadratic formula with a=1, b=30, c=215.
x=−b±√b2−4ac/2a
x=−(30)±√(30)2−4(1)(215)/2(1)
x=−30±√40/2
x=−15+√10 or x=−15−√10
You have to square it all up then add it up if you want you can use the calculator
