Answer:
0.25
Step-by-step explanation:
This is the question on conditional probability
Let A - the quadrilateral has four right angles
B - the quadrilateral has four equal side lengths
Required probability = P(B/A)
By definition of continuous probability


P(A) = 
Hence given probability = 
Step-by-step explanation:
5×a×5×a
collect like terms
5×5×a×a
25×a^2
25a^2
Subtract 50 mL from 62.4 mL to get the volume of the metal. Then, divide the mass (48g) by the volume to get your density
