The note A has a frequency of 880 hertz. The note D has a frequency of 1,175 hertz. Find the ratio of D to A to two decimal places. Express the answer in integer-ratio form. A. 4/3
B. 6/5
C. 5/4
D. 5/3
E. 3/2

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

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 %
