The vertex of a parabola is (3,2). A second point on the parabola is (1,5).which of the following points is also on the graph?
vekshin1
+ <span>The vertex of a parabola is (3,2),
that means the parabola's equation is y=a(x-3)</span>²+2
+ <span>A second point on the parabola is (1,5) and we replace x=1 and y=5. We have: 
5</span>=a(1-3)<span>²+2  ,  so we have 4a=5-2 or a=3/4
So the equation is y=3/4 (x-3)</span>²+2

And by checking we have the point (5;5) is on the parabola

Describe in words the region of R3 reperesented by the equations or inequalities x2+y2=4,z=-1
Roman55 [17]

Answer:

It represents a circle of radius 2, centered in the origin of the plane xy and transversal to the z-axis in z=-1.

Step-by-step explanation:

The first thing to notice is that

x^2+y^2=2^2

<u>represents a circle of radius 2</u>, with its center in the origin of a plane xy, of cartesians coordinates.

Starting from here, we have to put the coordinate z, to complete the space R³. <em>Then, the cirlce will "live" into the plane xy, where z=-1</em>.

Finally, we have that this region is a circle of radius 2, centered in the origin of the plane xy, and transversal to z=-1.

Regarding control charts, changing from two-sigma limits to three-sigma limits: A. decreases the probability that the process av
Dima020 [189]

Changing from Two-sigma limits to three-sigma limits helps to reduce the probability that defects will be generated by the process. Hence the correct answer is C.

<h3>What is a Two-Sigma Limit?</h3>

This is used to refer to the inclusion of about ninety-five percent of data plotted on the normal distribution curve.

Three sigma-limit on the other hand is a statistical calculation where data fall within three standard deviations from a mean.

If in a manufacturing firm, the quality control unit issues out a polity to reject products that are within two standard deviations to their accepted mean, then more errors will be captured thus resulting in a lot of loss or defective products.
