0.7
Low outlier = Q1 - 1.5(IQR)
High outlier = Q3 + 1.5(IQR)
Answer:
(C)26 units
Step-by-step explanation:
Since point B bisects AC into two equal parts
AB=BC
Since the two right triangles have side BD in common, we can then say that the two triangles are congruent and the length of the hypotenuses (AD and DC) are equal.
If AD=DC
8x-1=6x+9
8x-6x=9+1
2x=10
x=5
Now,
AB=3x-2
=3(5)-2
=13 Units
Since AB=BC
AC=AB+BC
=13+13
AC=26 units
The measure of AC is 26 units.
The Correct Answer is (E)<span> — Recall that congruent means that two polygons are the same shape and size. Since ∆</span>ABC<span> and ∆</span>ACD<span> are congruent, you know that each angle from one triangle corresponds to an angle of the other triangle. If you are having a hard time visualizing the triangles matching up, mark up the given diagram or draw your own to show the triangles side by side:</span>
Just by filling in the angles, you can see that the remaining angle in each triangle must be 60°. To find ∠BCD, simply sum ∠BCA and ∠ACD to get a total of 60° + 90° = 150°.
