The amount charged is an illustration of a linear equation.
Tina charges $39 for 4 hours
The given parameters are:
--- amount charged for the first hour
--- amount charged for the extra hours
If Tina babysits for 4 hours, it means that:
- <em>She will charge $15 for the first hour</em>
- <em>$8 for the extra 3 hours</em>
<em />
So, the total charges is:
The ordered pair is (4,39)
It means that:
She charges $39 for 4 hours

Answer:
3
Step-by-step explanation:
The y-intercept will be 8
And then you work out the slope by replacing the c, y and the x in y=mx+c
The y and x will be any of the coordinates above
So it will be 0=m(8)+(8)
0=8m+8
So 8m=-8
Therefore m=-1
So the y-intercept is 8 and the slope is -1
A a dilation and reflection
dilation will make bigger or smaller therefore it cannot be congruent
Yes it is possible. Consider the following scenarios
Scenario A:
Min = 5
Q1 = 10
Median = 12
Q3 = 18
Max = 22
The IQR is equal to the difference of Q3 and Q1
IQR = Q3-Q1 = 18-10 = 8
The range is the difference of the min and max
Range = Max - Min = 22 - 5 = 17
So in summary for scenario A, we have
IQR = 8
Range = 17
----------------------------------------------------------
Now consider another scenario, call it scenario B, where
Min = 100
Q1 = 102
Median = 105
Q3 = 110
Max = 117
I claim that the IQR and Range for scenario B is going to be the same as in Scenario A. Let's find out
IQR = Q3 - Q1 = 110 - 102 = 8
Range = Max - Min = 117 - 100 = 17
So
IQR = 8
Range = 17
which is identical to scenario A.
-------------------------------------------------------------------------------
Scenario B has completely different data than scenario A, yet the IQR and Range are equal to scenario A's counterparts. This shows that it is possible to have 2 completely sets of data yet have the same IQR and range.
The wrap up here, and the answer to the question, is "yes it is possible" with the explanation given above.
