Answer:
The percent of these mothers are between the ages 30-35 is 36.53%
Step-by-step explanation:
we are given
mean of age =31.7 years
standard deviation of 5.2 years
For age=30 years:
x=30
we can find z-score
we can plug values
For age=35 years:
x=35
we can find z-score
we can plug values
now, we can use normal distribution table
now, we can find percentage
=36.53%
To graph y-3x>-2, find the boundary line. (y > -2 + 3x is your answer)
1. Find the equation of the boundary line.
- y-3x>-2 is the equation.
2. Choose a point (x, y) on the shaded side on the line.
3. Plug x and y, in the boundary to identity the inequality sign.
