First I let's represent our data in the table and make a scatter plot ( i attached the image).

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.
PartBWe 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.
Answer:
V = 36 in³
Step-by-step explanation:
The volume of a rectangular prism is given by the formula V = l × w × h
Here our length is
, our width is 4, and our height is 
Plugging in these values to our formula give us 
V = 36 in³
Answer:
D
Step-by-step explanation:
Given
=
, then
=
=
= 262144 → D
Check the picture below.
so, plotting the first 5 points, let's notice f(x) is below the x-axis, and thus negative, after x = -4, going further to the left, it remains in the negative quadrants, down down down up to -∞.
notice, we use the parentheses for the -∞, because we don't know where it's, thus we'll never touch it, and we also use a parentheses on the -4, because, when x = -4, f(x) = 0, 0 is not a negative value, so -4) because is not included in the interval, but all numbers before it are.
Answer:

Step-by-step explanation:
The equation of a kind can be written in the slope intercept form, y= mx +c, where m is the gradient and c is the y-intercept.




Substitute the value of m into the equation:

To find the value of c, substitute a pair of coordinates.
When x= -3, y= -3,


c= -3 -1
c= -4
∴ The equation of the line is
.
