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:

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

What is the factored form of the quadratic equation y=x2+4x-12? <br><br> PLEASE HELP ME!!!

snow_tiger [21]

Answer:

(x + 6)(x - 2)

Step-by-step explanation:

The given quadratic equation is $y = x^2 + 4x - 12$ .

A quadratic equation can be factored in the form $(x - a) (x - b)$ where $-a$ and $-b$ will form the roots of the equation

Here the roots are $- 6$ and $2$ .

The factored form would simply be: $(x + 6) (x - 2) = 0$ .

Thus the answer.

(07.08 MC) The graph below shows the price, y, in dollars, of different amounts of peanuts, x, in pounds: Which equation best re

morpeh [17]

Answer:

B. y = 3x

Step-by-step explanation:

Since the y-axis is going up by 6's and the x-axis is going up by 2's, we can see that we would need to multiply the x-axis values by 3 to get our y-values. Therefore, our linear equation for this graph is y = 3x.
