Arianna answered 36 questions correctly on her multiple choice science final and earned a grade of 45%. How many total questions were on the final exam? If I can't get the answer I quit

72 is the answer to this problem

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

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 %
