Answer:
u=−x2−x+1
Step-by-step explanation:
Let's solve for u.
2x−u−1x^2−3x+3=2
Step 1: Add x^2 to both sides.
−x2−u−x+3+x2=2+x2
−u−x+3=x2+2
Step 2: Add x to both sides.
−u−x+3+x=x2+2+x
−u+3=x2+x+2
Step 3: Add -3 to both sides.
−u+3+−3=x2+x+2+−3
−u=x2+x−1
Step 4: Divide both sides by -1.
−u/−1=x2+x−1
−1/u=−x2−x+1
Answer:
u=−x2−x+1
Answer:
Answer is (x+3)(x+2)
3 time 2 equal 6
While 3 plus 2 equal 5

Step-by-step explanation:
A. No, the sample is not random. The sampling is biased because he limits his selection to only seventh graders.
B. The sample <em>is</em> random. The fact that all the students selected were eighth graders is coincidence, not bias. The sampling method was still random.
