What is the mean of the values in the dot plot?
Enter your answer in the box.
Answer:
The mean is 46.
Step-by-step explanation:
To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.
40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50
Multiply what's in the parentheses.
40 + 82 + 45 + 96 + 147 + 50
Add, going from left to right
122 + 45 + 96 + 147 + 50
167 + 96 + 147 + 50
263 + 147 + 50
410 + 50
460
Now, divide that by how many dots there were (10).
460/10
The mean of the values in this dot plot is 46.

What is the slope of the line shown below?
Answer:
D
Step-by-step explanation:
Slope formula: m = (y2 - y1) / (x2 - x1)
First coordinate: (1, 3)
Second coordinate: (3, 9)
m = (9 - 3) / (3 - 1)
m = (6) / (2)
m = 3

m ∠Y = 39°
Step-by-step explanation:
The sum of all angles in a triangle is 180°, so you just have to add m∠Z and m∠X, which will be 113 + 28 = 141. 180 - 141 = 39°
Answer:
if the shape is a triangle, just find the 3rd number and they should all add to 180 degrees.

What is the slope of the line that passes through the points (-5, -7) and (4,−1)? in the simplest form
Answer:
2/3
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points, then simplify:
(y2 - y1) / (x2 - x1)
(-1 + 7) / (4 + 5)
6/9
= 2/3
So, the slope of the line is 2/3

A horizontal line passes through the
point (0,4). A vertical line passes
through the point (-16,0). What is
the intersection of the two lines?
Given:
A horizontal line passes through the point (0,4).
A vertical line passes through the point (-16,0).
To find:
The intersection point of these two lines.
Solution:
A horizontal line passes through the point (0,4). It means the y-coordinate of each point on the line is 4 and the equation of the line is
[tex]y=4[/tex]
A vertical line passes through the point (-16,0). It means the x-coordinate of each point on the line is -16 and the equation of the line is
[tex]x=-16[/tex]
So, the coordinates of the intersection point of these two lines are (-16,4).
Therefore, the required point is (-16,4).
The point of intersection of the two lines is at point: (-16, 4).
According to the question;
The horizontal line passes through the point (0,4).The vertical line passes through the point (-16,0).If a horizontal line passes through the point (0,4).
In essence, the y-coordinate of each point on the line is 4 and the equation of the line is; y = 4If a vertical line passes through the point (-16,0).
In essence, the x-coordinate of each point on the line is -16 and the equation of the line is; x = -16Ultimately, the intersection point of the two lines as described is (-16,4).
