Answer:

The quadratic equation is $( 3x^{2} +6x -72)$

Step-by-step explanation:

The quadratic equation form f(x) = a ( x- α) (x-β)

The roots are −6 and 4 and whose leading coefficient is 3.

the quadratic equation is f(x) = 3 ( x- (-6)) (x-4) = $3( x^{2} -4x +6x-24)$

The quadratic equation is $3( x^{2} +2 x -24)$

<u>Final answer</u>:-

The quadratic equation is $( 3x^{2} +6x -72)$

Is 6/4 rational or irrational?

Serjik [45]

Hello, and thank you for posting your question here on brainly.

This fraction needs to be simplified to be able to figure it out.

The greatest common divisible is 2.

Divide the numerator and denominator by 2.

6/4 = 3/2

Now, do the division.

3/2 = 1.5

1.5 is rational.

Hope this helps! ☺♥

Answer:

Hi Grif05!

Your answer is 7.1 million.

To be exact , 7182000

Step-by-step explanation:

The distance between 2009 and 2012 is 3 years so we multiply.

11x3=33.

Now we must find 33% of 5.4 million.

33 % of 5.4 million is 1782000.

33% of 5400000 = 1782000

We then add 33% of 5.4 million to itself.

We get an answer of 7182000.

Hope this helps! Tell me if I'm wrong please :)

If the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs” what is the alternate hypothe

AlexFokin [52]

Answer:

“The true mean weight of the piglets is at most 39lbs”would be the alternate hypothesis.

Step-by-step explanation:

Given that the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”

We have to find the alternate hypothesis.

In hypothesis testing, alternate is the opposite of null hypothesis. If null hypothesis supports one statement alternate hypothesis opposes it. In other words, alternate hypothesis would be the negative of the claim of null hypothesis.

Here the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”

i.e H0: $x bar\geq 39 lbs$

So alternate hypothesis

Ha: $x bar\leq 39 lbs$
