(T + S) (x)

Step-by-step explanation:

Cost of manufacturing x T-shirts is T(x) = 4x + 10

Cost of manufacturing x sweatshirts is S(x) = 14x + 19

Total cost of manufacturing x T-shirts and x sweatshirts

= T(x) + S(x])

= (T + S) (x)

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 %
