Median: First we put the numbers in order from lowest to highest:
1
,
1
,
1
,
2
,
2
,
3
,
3
,
3
,
4
The median is the number that has the central position.
Median
=
2
Mode: it is the number that appears the most times. In this case, both
1
and
3
appear the same number of times, so they are both modes.
hope this helps!
Multiply all terms by the common denominator which is 15
All of the above. The graph of a line shows a point on the line, (x,y). It shows the slope (rise/run) it also shows the equation in point-slope form/slope intercept form.
(Slope intercept and point-slope are the same equation, but in a different form.)
Answer:
∠DFE ≅ ∠DFG
Step-by-step explanation:
we know that
Triangles are congruent by SAS, if any pair of corresponding sides and their included angles are equal in both triangles
In this problem we have that
The pair of corresponding sides that are equal are
EF=GF and DF (is the same side for both triangles)
The included angle are ∠DFE and ∠DFG
therefore
The additional information needed to prove that triangles DEF and DGF are congruent by SAS is that angles ∠DFE and ∠DFG are equal
so
∠DFE ≅ ∠DFG
