Make m the subject of the formula m/v - t/b = m-t/r
RoseWind [281]

Answer:

m =   - \frac{ \frac{t}{b} +  \frac{t}{r}  }{1 -  \frac{1}{v} }

Step-by-step explanation:

\frac{m}{v}  -  \frac{t}{b}  = m -  \frac{t}{r}  \\  \frac{m}{v}  -  \frac{t}{b}  +  \frac{t}{r} = m \\  -  \frac{t}{b}   +  \frac{t}{r}  = m -   \frac{m}{v}  \\  -  \frac{t}{b}  +  \frac{t}{r}  = m(1 -  \frac{1}{v} ) \\    - \frac{t}{b}  +  \frac{t}{r}  =  \frac{m( 1 -  \frac{1}{v})  }{(1 -  \frac{1}{v}) }  \\    - \frac{ \frac{t}{b}  +  \frac{t}{r} }{1 - ( \frac{1}{v} ) }  = m

Step-by-step explanation:

Given -

Let event A = student takes Spanish

Event  B = student takes Computer Programming

A \bigcap B  =   student takes Computer Programming and Spanish

P(B) = 0.4  ,  P(A \bigcap B) = 0.15

What is the probability that a student takes Spanish given that the student is taking Computer Programming =

(Probability of an event occuring given that another event has already occured , we use condition probability )

P(\frac{A}{B}) = \frac{P(A \bigcap B )}{P(B)}

         = \frac{.15}{0.4}

          =  0.375
