The answer to your problem is a<-2
In a symmetric distribution, better known as the Gaussian or normal distribution, two thirds of the observations or 66.67% of the observation belongs to the area between the -3∅ to +3∅ where ∅ is the standard deviation of the group. it is assumed here that the mean is 1 and the area under the curve is also 1.
Answer:
Step-by-step explanation:
Y=mx+b
Slope (m) is rise over run.
1. rise= 4 run=5 therefore, slope=4/5
y=4/5x+b
b= y intercept
b= 4
Y=4/5x+4
2. rise= 1 run= 2 slope = -1/2
b= -1
Y= -1/2x - 1
