Answer: Last option.
Step-by-step explanation:
For this exercise you need to find the Discriminant.
The formula used to find the Discriminant, is the following:

In this case, given the Quadratic equation:

You can identify that:

Knowing those values, you must substitute them into the formula and then you must evaluate in order to find the Discriminant.
You get that this is:

By definition, if:
Then the Quadraitc equation has 2 nonreal solutions.
Answer:
Mean is 83.7%
And, the standard deviation is 0.033
Step-by-step explanation:
The computation of the mean and the standard deviation is as follows:
Let us assume the P be the sample proportion
Mean is 83.7%
And, the standard deviation is

= 0.033

<em>The x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>
<h2 /><h2>
Explanation:</h2>
The Standard Form of the equation of a line is given by:

So:

is written in Standard Form. The x and y intercepts are:

So:
FOR X-INTERCEPT:

FOR Y-INTERCEPT:

Finally,<em> the x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>
