Answer:
units to the right and
units down
Step-by-step explanation:
we have
This is a vertical parabola open upward with vertex at point
Step 1
Convert the function g(x) into vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
The function g(x) is a vertical parabola with the vertex at point
Step 2
Find the rule of the translation
That means
The translation is units to the right and
units down
Answer:
Step-by-step explanation:
Given : sample size : n= 51
sample standard deviation : s= 0.46
Significance level :
Using chi-square distribution, the critical values will be :
Confidence interval for population standard deviation () :
Substitute all the values , we get
Hence, the 95% two-sided confidence interval for σ :
