The perimeter is? Somebody help please

The perimeter is 52

Step-by-step explanation:

Just add all the numbers together

13 + 9 + 3 + 7 + 5 + 15 = 22 + 10 + 20 = 32 + 20 = 52

the radius is 2 times the diameter.

step-by-step explanation:

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 %
