Please help me! Quick! Samir draws triangle PQR in the coordinate plane as shown. Then he rotates triangle PQR 90 degrees counterclockwise around the origin to form triangle P'Q'R'. Samir Incorrectly says the coordinates of Q' are (5.-4) (5,-4). What is the correct answer? How might Samir have gotten his answer?

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 %

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared

step-by-step explanation:

noncoplanar points are points that do not lie on the same line.
