p^2+6p+9=0
The discriminant of a quadratic is the expression inside the radical of the quadratic formula.
b^2−4(ac)
Substitute in the values of
a, b, and c.
6^2−4(1⋅9)
Evaluate the result to find the discriminant.
36-4(9)
36-36

Hello!
So the problem is 2x-8 = 2(x-4). First off, let's perform the distributive property on the right side of the expression. 2 * x is 2x. 2 * -4 is -8. That makes the right side 2x-8. 2x - 8 = 2x-8, so nothing else needs to be done. Because both sides are identical, all real numbers are the solution.
Considering the p-value, the decision is described as follows:
Since the p-value is less than , we reject .
<h3>What is the relation between the p-value and the conclusion of the test hypothesis?</h3>
Depends on if the p-value is less or more than the significance level:
- If it is more, the null hypothesis is not rejected.
- If it is less, it is rejected.
In this problem, we have that:
- The p-value is of 0.0739.
- The significance level is of 0.1.
Hence:
Since the p-value is less than , we reject .

My guess is that the exact answer would be $2544.75 because you would first multiply 2900 by .0675 to get 195.75. Then you would multiply that by 13 to get 2544.75.
