This is the "commutative property of addition." The order in which you add numbers together doesn't matter, and doesn't change your final results.

Which of the following represents two lines that are coplanar and do not intersect?

OverLord2011 [107]

Question:

Which of the following represents two lines that are coplanar and do not intersect?

A. Perpendicular

B. Skew

C. Parallel

D. Intersecting

Answer:

Two lines that are co -planar and do not intersect is Parallel.

Step-by-step explanation:

Two lines are said to be parallel if they lie in the same plane, and are the same distance apart over their entire length.Each line has many parallels. Any line that has the same slope as the original will never intersect with it. Hence Parallel Lines would never cross, even if extended forever. Technically parallel lines are two coplanar which means they share the same plane or they're in the same plane that never intersect

What is the discriminant D of the equation? a2−2a+5=0 Enter your answer in the box.

xxMikexx [17]

For a quadratic equation ax^2 + bx + c = 0, the discriminant is given by b^2 - 4ac
Thus for a^2 - 2a + 5 = 0,
a = 1, b = -2 and c = 5
b^2 - 4ac = (-2)^2 - 4(1)(5) = 4 - 20 = -16

The data below shows the minimum wage requirement of the u.s government in years,x, after 1960. Based on the data provided what

mixas84 [53]

Answer:

<em>Option c</em>

Step-by-step explanation:

<u>Best Fit Regression Model </u>

When experimental data is collected, scientists frequently ask themselves if there is a relationship between some of the variables under study. It's crucial in modern times where artificial intelligence technology is trying to find key answers where traditional approaches hadn't before.

One of the most-used tools to find relations between variables is the regression model and its best fit lines to try to find an expression who relates variable x (years from 1960) and variable y (minimum wage requirement) as of our case.

The provided data was entered into a digital spreadsheet and an automatic function was applied to find the best-fit model.

We found this equation:

$y=0.11363x+0.6906$

when rounded to three decimal places, we find

$y=0.114x+0.691$

Which corresponds to the option c.
