Start by looking at the vertex form of a quadratic function, f(x) = a(x - h)^2 + k. The variables h and k are the values of the vertex. Plug those in to get f(x) = a(x - 4)^2 + 5. To find the variable a, plug in the point given for the x and y values. So, you get (21) = a((8) - 4)^2 + 5. Solve for a algebraically, and you get a = 1. Finally, plug everything in and simplify the equation. You should get that the quadratic function is f(x) = x^2 - 8x + 21. Hope this helps!

kvv77 [185]

Answer:

The correct answer is D- 29,544 ovens

Step-by-step explanation:

To find the answer, we simply need to find 20% of 24,620 ovens and add it to that sum. To find 20% of 24,620, we can simply multiply 24,620 by .2.

24,620*.2=4924

Then, add the extra 4924 to 24,620

4924+24620=29544

The correct answer is 29,544 ovens

Hope this helps! :D

Step-by-step explanation:

From Normal distribution tables the z score for 95% CI  = 1.96.

Confidence Interval

= 1.35 +/- 1.96 * 0.63/√40

=  1.35 +/- 0.195

=  (1,155, 1.545).
