Answer:
9, 12, 15
Step-by-step explanation:
Using the recursive formula and T₁ = 6 , then
T₂ = T₁ + 3 = 6 + 3 = 9
T₃ = T₂ + 3 = 9 + 3 = 12
T₄ = T₃ + 3 = 12 + 3 = 15
Answer:
The sample is the 150 randomly selected customers.
Step-by-step explanation:
When you survey a group of people, to gauge whaever you are interested, these people are what makes your sample.
In this question:
Nick surveys 150 randomly selected customers to determine whether or not they were satisfied.
So the sample is the 150 randomly selected customers.
Answer:
1.
Part A: Yes, it is (a - b)².
Part B: a² - 2ab + b² => (x - 6)² = x² - 12x + 36.
Part C: x² - 12x + 36.
2.
Part A: Not a special product.
Part B: Binomial distribution => (x + 8)(x + 1) = x² + 9x + 8.
Part C: x² + 9x + 8.
3.
Part A: Yes, it is (a + b)²
Part B: a² + 2ab + b² => (3x + 2)² = 9x² + 12x + 4.
Part C: 9x² + 12x + 4.
4.
Part A: Yes, it is (a + b)(a - b), a difference of squares.
Part B: a² - b² => 4x² - 49
Part C: 4x² - 49
5.
Part A: Not a special product.
Part B: Binomial distribution => (x - 5)(2x - 5) = 2x² - 15x + 25.
Part C: 2x² - 15x + 25
