A line segment from a vertex to the midpoint of the opposite side is a "median". A median divides the area of the triangle in half, as it divides the base in half without changing the altitude.
AAMC is half AABC. AADC is half AAMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
ABMC is half AABC. ABMD is half ABMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
Then, AADC = 1/4 AABC = ABMC, so AADC = ABMC by the transitive property of equality.
Answer:
a. 1.75
Step-by-step explanation:
r values, or the correlation coefficient must be between -1 and 1, inclusive
-1 is a perfect negative correlation
0 is no correlation
+1 is a perfect positive correlation
1.75 is not between -1 and 1
For this case we have the expression:
"the square root of 4" is represented algebraically as:
Then, we can express the given statement as:
They are similar terms, we can subtract:
By definition of power properties we have that:
Then the expression is reduced to:
Answer:
Answer:
Using Pedmas rule:
<u>subtract: 6-6 = 0</u>
<u>simplify the following</u>
<u>the numerator and denominator cancels out</u>
