Answer:
Step-by-step explanation:
The vertex form of a parabola is given by:
, where V(h,k) is the vertex of the parabola.
The given parabola has vertex (1,1).
This implies that: .
Put these values into the vertex form equation.
The y-intercept of this parabola is: (0,-3).
This point lies on the parabola hence it must satisfy its equation.
The equation now becomes
To find the x-intercept, put y=0 into the equation:
Divide through by -4.
Take plus or minus square root of both sides.
or
or
Therefore the x-intercepts are:
To the nearest hundredth, we have

Step-by-step explanation:
The chi-square test is majorly used to test relationship/association between two categorical variables. The use of the chi square test is to ask the question: if there is a significant relationship between company A and B.
But this study only aims to compare company A and B cell phone service and not to establish a relationship between the two company's cell phone service
