starting from the origin, explain how to plot the following three points accurately: (2, −2) (−2, 1.5) (−1, fraction 2 over 4)

:/

Step-by-step explanation:

1 a. You would go 2 right and two down and place a point

1 b. You would go 2 left then go 1.5 up and place a point

1.c you would go 1 left and 2/4 up and place a point

you're missing vital information, add to it so we can solve this problem for you.

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 %
