We are given parabola equation y=x^2-10x+30.
We need to convert it in vertex form y= a(x-h)^2+k.
We need to find the value of a, h and k to get the vertex form.
For the given equation y=x^2-10x+30, the coefficient of x^2 is 1.
Therefore, a=1.
Now, let us find values of h and k.
h = -b/2a.
h = -(-10)/2(1) = 5.
Plugging x=5 in given equation to get the value of k.
y= x^2-10x+30 => (5)^2 -10(5) +30 = 25 -50 +30 = 5.
Therefore, k =5.
Therefore, vertex (h,k) = (5,5).
<h3>So, the vertex form is </h3>Answer:
The planning value for the population standard deviation is of 4330.
Step-by-step explanation:
Uniform probability distribution:
The uniform probability distribution has two bounds, a and b. The standard deviation is given by:
Annual starting salaries for college graduates with degrees in business administration are generally expected to be between 20000 and 35000.
Uniform in this interval, so
What is the planning value for the population standard deviation?
The planning value for the population standard deviation is of 4330.
