Answer:

Step-by-step explanation:

4x(3x-7)-19x2

4x*3x=12x

-7*-19 = 133 * 2 = 266

12x + 266

Don't Trust This I suck at math, but I am confident that is the answer. It's either that or this: 12x-52. Trust me if you want. But I am warning you.

Answer:

The answer is

<h2>-7x² - 28x</h2>

Step-by-step explanation:

4x(3x − 7) − 19x²

Expand the terms

We have

12x² - 28x - 19x²

Group like terms

That's

12x² - 19x² - 28x

Simplify the terms

We have the final answer as

<h3>-7x² - 28x</h3>

Hope this helps you

Suppose you carry out a significance test of h0: μ = 8 versus ha: μ &gt; 8 based on sample size n = 25 and obtain t = 2. 15. Fin
OLEGan [10]

Using a t-distribution calculator and finding the p-value, the correct option regarding the conclusion is given by:

a) the p-value is 0.02. We reject h0 at the 5% significance level because the p-value 0.02 is less than 0.05.

<h3>What is the relation between the p-value and the conclusion?</h3>

It also involves the significance level, as follows.

  • If the p-value is less than the significance level, we reject the null hypothesis h_0.
  • If it is more, we do not reject.

In this problem, a t-distribution calculator for a right-tailed  with <em>t = 2.15 and 25 - 1 = 24 df</em> is used to find a p-value of 0.02.

It is less than 0.05, hence option a is correct.
