Answer:
PART A:
The range, the IQR (inter-quartile range) and the standard deviations are measures which are used to measure the spread of a data set.
A dataset is more consistent relative to another data set when the standard deviation is less than that of the other data set.
From the table, it can be seen that Team C has the least standard deviation.
Therefore, If the club wants to award the team that has the most consistent scoring among its team members, team C should be chosen.
PART B
The mean and the median is a measure of center of a data set.
The mean describes the average of a data set.
From the table, it can be seen that Team B has the highest average score.
Therefore, If the club wants to award the team with the highest average score, team B should be chosen.
ANSWER

EXPLANATION
The given function is

Let us split the middle term to get,

We factor to obtain,


Let us find the zeros of f(x),

Either


We need to find the x-value of the vertex, which is the midpoint of the x-intercepts.
This gives us,

Hence the axis of symmetry of the parabola has equation,

Since the given function has minimum turning point, it will decrease and then increase.
The function will be increasing for

The function will be increasing and positive for
Answer:
The slope is 4/3
Step-by-step explanation:
Slope is found by using the equation
m = (y2-y1)/(x2-x1)
where (x1,y1) and (x2,y2) are two points
m=(1--3)/(1--2)
= (1+3)/(1+2)
= 4/3
