1. the table shows values of a function . what is the average rate of change of over the interval from x = 5 to x = 9? show your work.

x 4 5 6 7 8 9 10

8 10 11 14 18

Average change of rate = 4

Step-by-step explanation:

The average rate of change is going to be the final value mines the initial value, divided by the change in the input of the function.

Average change of rate = (14 - (-2)) / 9 - 5 = 16/4 = 4

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

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 %
