You take 2.6666 times 1.55555
The slope of a line can be calculated from any two points on that line.
slope=m=(y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are two points.
In this case:
m=(6-6)/(4--2)
m=0/6
m=0
Since the slope is zero, this is just a horizontal line, specifically the line:
y=6
Answer:
The proportion of electric toothbrush prices are between 104.60 dollars and 108.20 dollars is 0.0099
Step-by-step explanation:
A set of electric toothbrush prices are normally distributed with a mean of 87 dollars and a standard deviation of 8 dollars.

Standard deviation = 
We are supposed to find proportion of electric toothbrush prices are between 104.60 dollars and 108.20 dollars i.e.P(104.60<x<108.20)

At x = 104.60

Z= 2.2
At x=108.20

Z= 2.65
Refer the z table for p value :
P(x<108.20)-P(x<104.60)=P(Z<2.65)-P(Z<2.2)=0.9960-0.9861=0.0099
Hence The proportion of electric toothbrush prices are between 104.60 dollars and 108.20 dollars is 0.0099
