The quantities xxx and yyy are proportional. xxx yyy 888 1.61.61, point, 6 151515 333 222222 4.44.44, point, 4 Find the constant of proportionality (r)(r)left parenthesis, r, right parenthesis in the equation y=rxy=rxy, equals, r, x. r =r=r, equals

r=0.2

Step-by-step explanation:

If y=rx

When x=8, y=1.6

When x=15, y=3

When x=22, y=4.4

Clearly, r=0.2.

However, one case is sufficient to find the value of r. THe three are done to help draw a definitive conclusion.

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 %

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
