Step-by-step explanation:
what is the mean absolute deviation of Astrids data? to answer the question, find the mean. Next, fill in the table for the absolute deviation of each score in the data set from the mean. then find the sum or the deviations. finally, use the sum or the absolute deviations to find the mean of the absolute deviation.
Answer:
The mean absolute deviation is the mean distance of each value in the data set from the mean value of the data set. To find the mean absolute deviation, first find the mean of the data set.
The sum of the values in the data set is 15 + 20 + 25 + 15 + 0 + 15 + 30 + 40 + 35 + 20 + 15 + 25 + 30 + 10 + 5 = 300. The number of values in the data set is 15.
Calculate the mean of the data set using this formula:
mean .
Next, find the absolute deviation of each value in the data set from the mean by subtracting each value from the mean and taking the absolute value.

Select the sets of angles that could be the interior angle measures of a triangle.
85°, 43°, and 52°
90°, 37°, and 51°
37°, 65°, and 78°
120°, 12°, and 40°
162°, 2°, and 16°
Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer: I think it is vertical
Step-by-step explanation:
Answer:
vertical, x=25
Step-by-step explanation:
The angles are vertical angles and vertical angles are equal
75 = 4x-25
Add 25 to each side
75+25 = 4x-25+25
100 = 4x
Divide each side by 4
100/4 = 4x/4
25 =x

write an equation of the line. (-3,2),(0,-1)????
please i need it lol
Answer:
y = -x -1
Step-by-step explanation:
Use slope = rise/run to find the equation. The y intercept is given to you ( when x is 0, the y value is always the y intercept) so you add a -1.
Find the value of x.
