answer:
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
Step-by-step explanation:
Sample size = 85 followed a vegetarian diet
Period = 4 months,
Mean systolic blood pressure= 124 mmHg
Sample size = 75 followed non-vegetarian diet
Period = 4 months
Mean systolic Bp = 138 mmHg
Reasons/explanations
Given that p -value < 0.01 we will reject the null hypothesis

Answer:
Length 
Width 
Step-by-step explanation:
Let
x-----> the length of rectangle
y ----> the width of rectangle
we know that
The area of rectangle is equal to


so
----> equation A
---> equation B
substitute equation B in equation A and solve for y

Solve the quadratic equation by graphing
The solution is 
see the attached figure
Find the value of x

therefore
Length 
Width
