Answer:elect the scenarios that are related to providing clarity in a research survey.
The survey’s research question analyzes a loss of market share.
A company uses an online survey.
A company surveys customers at all locations.
The survey contains a rating scale and rank order questions.
A focus group field-tests the survey.
A company creates an overview of topics to address.
The survey contains ten items.
Answer:
c. 5 - 17
Step-by-step explanation:
a. -15 - 3 = -18
b. -3 - (-9) = 6
c. 5 - 17 = -12
d. -6 - (-6) = 0
We have, Discriminant formula for finding roots:
Here,
- x is the root of the equation.
- a is the coefficient of x^2
- b is the coefficient of x
- c is the constant term
1) Given,
3x^2 - 2x - 1
Finding the discriminant,
➝ D = b^2 - 4ac
➝ D = (-2)^2 - 4 × 3 × (-1)
➝ D = 4 - (-12)
➝ D = 4 + 12
➝ D = 16
2) Solving by using Bhaskar formula,
❒ p(x) = x^2 + 5x + 6 = 0
So here,
❒ p(x) = x^2 + 2x + 1 = 0
So here,
❒ p(x) = x^2 - x - 20 = 0
So here,
❒ p(x) = x^2 - 3x - 4 = 0
So here,
