Perpendicular bisectors are segment that passes through the mid point of a triangle, while altitude is the perpendicular distance from the base to the opposite vertex.
Answer:
Step-by-step explanation:
Use the formula to find the z-score, then go to the table that will give you the probability that the value is less than this z-score.

The probability that the value lies to the left of 1 on a standard bell curve is 84.1345%, or 84%, the third choice down.
Answer:
4.5
Step-by-step explanation:
The formula for solving area in parallelograms is base x height.
The base is 2.5 and the height is 1.8
2.5x1.8=4.5
Answer: 3(10x+5)
Step-by-step explanation: 30/3=10x + 15/3=5
Answer:
( a+b) ( m^2 + n^2)
Step-by-step explanation:
factorise like terms
m^2 ( a + b ) + n^2 ( m^2 + n^2)
then put like terms together put remaining terms in a bracket
( a + b) ( m^2 + n^2 )
