Answer:
The answer to your question is: BD = 7.5
Step-by-step explanation:
Data
C is the midppoint of AD
B is the midpoint of AC
AC = 5
BD = ?
Process
We know that B is the mid point of AC, then AB = BC
AB + BC = 5
but 2AB = 5
AB = 5/2
AB = 2.5 = BC
Then AC = CD if AC = 5 then CD = 5
Finally
BD = BC + CD
BD = 2.5 + 5
BD = 7.5
To find the mean absolute deviation of the data, start by finding the mean of the data set.
Find the sum of the data values, and divide the sum by the number of data values.
Find the absolute value of the difference between each data value and the mean: ...
Find the sum of the absolute values of the differences
-3x+9 = -3(2x+3) + 3(x-4)+1
distribute
-3x+9 =-6x-9+3x-12+1
add like terms
-3x+9= -3x-20
add 3x to each side
9 = -20
there are no solutions because 9 does not equal -20
