52.8 is the answer.
Hope this helps!
(n - 4) - 3 = 3 - (2n + 3)
Let's first start by removing the parenthesis.
(n-4) = +(n-4) so we just remove the parenthesis without changing the signs. So the first part of the equation will be n - 4 - 3.
Before (2n+3), we can notice a minus sign (-) which means that to remove the parenthesis, we need to change the signs of the numbers and variables inside.
-(2n+3) = -2n-3
So the second part of the equation becomes 3 -2n - 3
(n-4) - 3 = 3 - (2n+3)
n - 4 - 3 = 3 - 2n - 3
n - 7 = -2n
Now we need to put the variables apart and the constants apart. So we subtract n from each side:
n - n - 7 = -2n - n
-7 = -3n
Divide both sides by -3
(-7)/(-3) = (-3n)/-3
7/3 = n
In the equation (n-4) - 3 = 3-(2n+3), the value of n is n=7/3
Hope this helps! :)
The answer would be -1/32 i think.
The lower quartile is the mean of the lower half of the data set, not incuding the median value. In this case, the lower half is 5, 8, 10, 20 and the median is 9.
