A passenger can travel home to another city by either car (C), ferry (F), plane (P), or train (T). In a given year, the passenger makes 40, 25, 15, and 20 trips respectively by the four modes. The probability of being delayed using car (C), ferry (F), plane (P), and train (T) are 0.1, 0.2, 0.15, and 0.25 respectively. What is the probability of the passenger being delayed in the next trip?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

step-by-step explanation:

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
