A= b/c solve for b
solve for the indicated variable.
explain your answer!

b = ac

Step-by-step explanation:

To solve for b, you would have to isolate this variable. To do so, since you can see that b is the numerator and c is the denominator in the fraction, you can multiply both sides of the equation by c to isolate b.

b/c * c = a * c

The final answer is b = ac.

b. astronomers

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
