<h2>The graph of y = ax^2 + bx + c </h2><h2>A nonlinear function that can be written on the standard form </h2><h2>ax2+bx+c,where a≠0 </h2><h2>All quadratic functions has a U-shaped graph called a parabola. The parent quadratic function is </h2><h2> y=x2 </h2><h2> The lowest or the highest point on a parabola is called the vertex. The vertex has the x-coordinate </h2><h2>x=−b2a </h2><h2>The y-coordinate of the vertex is the maximum or minimum value of the function. </h2><h2>a > 0 parabola opens up minimum value </h2><h2>a < 0 parabola opens down maximum value </h2><h2> A rule of thumb reminds us that when we have a positive symbol before x2 we get a happy expression on the graph and a negative symbol renders a sad expression. </h2><h2>The vertical line that passes through the vertex and divides the parabola in two is called the axis of symmetry. The axis of symmetry has the equation </h2><h2>x=−b2a </h2><h2>The y-intercept of the equation is c. </h2><h2> When you want to graph a quadratic function you begin by making a table of values for some values of your function and then plot those values in a coordinate plane and draw a smooth curve through the points.</h2>

7. The claim that started this investigation was that students majoring in engineering are more likely to be in the marching ban

Genrish500 [490]

Answer:

See explanation below.

$P(M|E) > P(M|O)$

Step-by-step explanation:

Notation

First we need to define the following events:

E = The student is in a major of enginnering

O= The student is in a major different from enfinnering

M= The student is in the marching band

Solution for the problem

For this case we can calculate the following probability:

$P(M|E) =\frac{P(M and E)}{P(E)}$

And that represent the following event: "Given a randomly selected student is an engineering major, what is the probability the student is in the marching band"

And the probability that need to calculate to compare is this one:

$P(M|O) =\frac{P(M and O)}{P(O)}$

And that represent the following event: "Given a randomly selected student is NOT an engineering major, what is the probability the student is in the marching band"

And if the claim is satisfied we need to see this:

$P(M|E) > P(M|O)$

A cup contains 3 blue paper clips,2 red paper clips,and 5 silver paper clips.what is the probability of not drawing a red paper

Elis [28]

Short Answer 0.8

Remark
The total number of possible draws is
3 Blue + 2 Red + 5 silver = 10
There are two ways of solving this, both of which will be used later on.

Method 1
If you don't draw a read paper clip, that means you will draw a silver or blue paper clip.
$\frac{Silver + blue}{10} = \frac{3 + 5}{10} = \frac{8}{10} = \text{0.8}$

Method Two
The other way is to draw a red one and take that probability away from 1.
P(red) = $\frac{2}{10} = \text{0.2}$
1 - 0.2 = 0.8 Same answer.
