1/6=4/24
2/3=16/24
1/4=6/24
4/24+16/24+6/24=26/24=13/12=1+(1/12)

Answer:
The region between one standard deviation from the mean is (400,600) which should be 68.27% of the data.
Step-by-step explanation:
The mean of this data set is 500 and the standard deviation is 100. The data that are within one standard deviation of the mean, must be in the range between 400 and 600, which according to the normal curve should be about 68.27% of the samples. The shaded region is shown in red on the attached figure.
Answer:
x = 6
Step-by-step explanation:
y = 3 is a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 3
A line perpendicular to this will be a vertical line parallel to the y- axis with equation
x = c ( c is the value of the x- coordinates the line passes through )
the line passes through (6, 8 ) with x- coordinate 6 , then
x = 6 ← equation of perpendicular line
