150 students. there are two hands. therefore, 50% chance of being left handed, 50% chance of being right handed. 50%= half. half of 300=150. 150 students should be expected to be left-handed.

Answer:
The coordinates of point A are .
Step-by-step explanation:
The location of point A is defined by the vectorial sum of absolute coordinates of point P and coordinates of point A relative to coordinates of point P, that is:
(1)
- Absolute coordinates of point P.
- Absolute coordinates of point A.
- Vector to point A relative to point P.
If we know that and , then the absolute coordinates of point A are:
The coordinates of point A are .
Answer:
Dimension = 30.4 x 15.2 cm
Perimeter = 91.2 cm
Explanation:
Let width of rectangle be a, so the length of rectangle = 2a.
From the figure given we have by Pythagoras theorem
So, width of rectangle = 15.2 inches.
Length of rectangle = 30.4 inches.
Perimeter = 2 x (15.2 + 30.4) = 91.2 cm
Dimension = 30.4 x 15.2 cm
Perimeter = 91.2 cm
