Answer: -4/3x - 6
Step-by-step explanation:
First, let's find the slope of the line
y=- -4/3x+11
As the equation is already in slope-intercept form y=mx+c ,
Slope = -4/3
Let a point (x,y) be on the new line.
By finding the slope again,
y−2/x+6= -4/3
y−2= -4/3(x+6)
y−2= -4/3x−8
y = -4/3x - 6

Answer:
The range of the 95% data (X) = 238.3 days < X < 289.9 days
Step-by-step explanation:
Given;
mean of the normal distribution, m = 264.1 days
standard deviation, d = 12.9 days
between two standard deviation below and above the mean is 96% of all the data.
two standard deviation below the mean = m - 2d
= 264.1 - 2(12.9)
= 238.3 days
two standard deviation above the mean = m + 2d
= 264.1 + 2(12.9)
= 289.9 days
The middle of the 95% of most pregnancies would be found in the following range;
238.3 days < X < 289.9 days
