Density = Mass/Volume
Mass= Density x volume
Volume= mass/density
Answer:
Prob = 13/1024 = 0.0127
Step-by-step explanation:
Prob {A correct answer} = Correct option / Total options = 1/4
Prob {A wrong answer} = Wrong options / Total options = 3/4
Prob [3 answers correct] = P (3 correct ,& 2 wrong) or P (4 correct ,& 1 wrong) or P (5 correct, & no wrong)
= [ (1/4) x (1/4) x (1/4) x (3/4) x (3/4) ] + [ (1/4) x (1/4) x (1/4) x (1/4) x (3/4) ] + [ (1/4) x (1/4) x (1/4) x (1/4) x (1/4) ]
( 9/1024 ) + ( 3/1024 ) + ( 1/1024 )
13/1024 = 0.0127
Answer:
Calculate the determinant. Calculate the matrix of cofactors. Transpose the matrix of cofactors to obtain the adjugate matrix. Divide each entry of the adjugate matrix by the determinant to obtain the inverse.
We know a square is four equal sides. Saying this there are seven squares between A and C so, with the knowns of four equal sides and seven square between A and C you can divide 42/7=6. With this information count six squares to the right from A and the same for C with a result of
B(2,4), and D(2,-3) per graph.
