C because if you look at the intercept it’s a y and the y inception is equivalent to 4 so y=4x-14
Answer:
It's a
Step-by-step explanation:
This is a quadratic expression with the highest power of X being 2.
The coefficient of X² = 1
Note that the general form of a quadratic equation is aX² + bX + C
In this question,
a = 1
b = 7
C = 10
First step is to multiply a and C ( a x C)
= 1 X 10 = 10
Then, find 2 factors of 10 which can both add up to give 7, the coefficient of X given in the question.
The possible factors of 10 are 5 and 2. The sum of 5 and 2 is
5 + 2
Hence, the equation can be written as;
X² + 7X + 10 = X² + 5X + 2X + 10
The next step is to group using a bracket and factorise each bracket individually
(X² + 5X) + (2X + 10) =
X( X + 5) + 2( X + 5) =
(X + 5) (X + 2)
(X + 5) (X + 2) are the factors of the quadratic equation, X² + 7X + 10
Answer: a. Population = Fortune companies
b. Parameter = proportion of companies did not find that such surveys intruded significantly on their workday.
c. Sampling frame= List of all Fortune companies.
d. sample size = 500.
Step-by-step explanation:
Population is the largest group of individuals of objects that are point of interest for a researcher.
Here, Population = Fortune companies
Parameter is the measure of characteristic of a population.
Here, Parameter = proportion of companies did not find that such surveys intruded significantly on their workday.
Sampling frame = List of all individuals in population.
Here , Sampling frame= List of all Fortune companies.
Sample is a subset of population , here sample size = 500.
