(HELP ME PLEAS!!! I REALLY NEED TO PASS MY PRE-CALC FINAL) A vertical flagpole casts a shadow of length 15 feet at a certain time. If the angle of
elevation from the end of the shadow to the top of the pole is 65°, then an expression for
the length of the pole is?

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

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 %
