Answer:
The correct option is B.
Step-by-step explanation:
The given graph represents the sales of sweaters and gloves at her store for the past ten winter weeks.
If the scatter points lie near to a straight line and the slope of the line is positive, then there is a strong positive linear correlation between two variables.
r=1 means strong positive correlation.
r=0 means no correlation.
r=-1 means strong negative correlation.
From the figure it is clear that the scatter points lie near to a straight line and the slope of the line is positive. So, there is a positive linear correlation between the sales of sweaters and gloves.
Therefore the correct option is B.

Answer:
a) Table and graph showed
b) The distance will be 231 miles
c) Yes
Step-by-step explanation:
We know the van gets 22 mi/gal, so the distance D in miles traveled by the van can be expressed as
D(g)=22g, being g the number of gallons of gas used
a) The graph of the function D and its corresponding table of values is shown below.
b) If the van used g=10.5 gallons of gas, the distance would be:
D(10.5)=22 x 10.5 = 231 miles
c) The values of g are real in nature because they represent the amount of gas consumed by the van and it can be any real positive number. Being D a linear function of g, it also happens to take positive real values. Then it makes sense to connect the points with lines.
