What is the equation of the midline for the function f(x) ? f(x)=3cos(x)−2.5

the equation for the mid line is y = -2.5

Step-by-step explanation:

The given equation is

On comparing this equation with

A = 3

B = 1

C = 0

D = -2.5

The mid line for the equation is

y = D

Substituting the value of D

y = -2.5

Thus, the equation for the mid line is y = -2.5

step-by-step explanation:

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 %
