True
True
False since it would be 16.28
To determine the number of subjects that are needed for the experiments, we multiply the number of independent variables with the number of scores. For example, there are n independent variables then, there are approximately,
number of subjects = 20 x n = 20n
The correct statement is C. <span>If an angle is an acute angle, then the angle measures less than 90 degrees.
A and B are obviously incorrect, and D is incorrect because it can be other angle as well, not just acute. </span>
Answer:
A
Step-by-step explanation:
The volume (V) of water in the tank is calculated as
V = lbh (l is length, b is breadth and h is height )
Here l = 80, b = 40 and h = 50 , then
V = 80 × 40 × 50 = 160000 cm³
V ( in litres) = 160000 ÷ 1000 = 160 litres , then
number of times = 160 ÷ 10 = 16
81 / 180 = 0.45
The answer is 45%.
