Answer:

Linear pair

Step-by-step explanation:

<1 and <2 lie on a straight line.

Angles that lie on a straight line are considered as linear pair angles.

Linear pair angles sum up to 180°, which is the measure of a straight line angle.

Which is the equation of the parabola?

Umnica [9.8K]

Answer: $y=-\dfrac{1}{8}(x - 2)^2 - 3$

Step-by-step explanation:

The vertex form of a parabola is: y = a(x - h)² + k where

(h, k) is the vertex
$a=\dfrac{1}{4p}$

NOTE: p is the distance from the vertex to the focus

The vertex (h, k) is (2, -3)

$p=-2\quad \implies\quad a = \dfrac{1}{4(-2)}=-\dfrac{1}{8}$

Insert those values into the vertex formula to get:

$y=-\dfrac{1}{8}(x - 2)^2 - 3$

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they spend on soc

kolbaska11 [484]

First I let's represent our data in the table and make a scatter plot ( i attached the image).
$\begin{tabular}{ll} x & y \\ 0.5 & 100 \\ 2 & 100 \\ 1 & 95 \\ 3 & 85 \\ 3 & 78 \\ 5 & 75 \\ 5 & 72 \\ 6 & 70 \\ 6 & 98 \\ 7 & 60 \\ \end$
Points labeled A are called data set.
Point labelled B is called the outlier. The outlier is a point that does not fit well with the rest of our data set. Posible reason for point B is that someone is super smart and they don't need to spend a lot of time studying to achieve good results.
PartB
We can see from the graph that the number of hours spent on social media and test scores are negatively correlated. See a scatter plot, I added the trend line.
In other words, the more hours you spend on social media the lower your test scores should be.
