I don't understand the last question
The third quartile of this data set is B. 24.
Answer:
1/2
Step-by-step explanation:
3 or less is half the numbers on the cube.
3/6 simplifies to 1/2
Answer:
They are all squared
Step-by-step explanation:
Given f(x)=|x-2|-3
f(0) = |0-2|-3 = |-2| -3 = 2-3 = -1
So we need to solve f(a) = |x-2| = -1
Solving an absolute value problem is like having two equations,
(x-2)-3 = -1..................(1), and
-(x-2)-3 = -1................(2)
Solving (x-2)-3 = -1 => x=-1+2+3 = 4
Solving -(x-2)-3 = -1 => -x+2-3 = -1 => x=2-3+1=0 which is our previous answer.
So from the solution of x = 4, we note that 4>0, this means a=4.
