Find the perimeter of ABC.
sergejj [24]

If two shapes are similar, they are scaled by some factor. In other words, you have

AB = k\cdot ED,\quad AC = k\cdot DF,\quad BC = k\cdot EF

In particular, we know that

BC = 15 = k\cdot 5 = EF

And we deduce k=3

So, the perimeter of ABC is

AB+BC+AC = 3ED+3EF+3DF = 3(ED+EF+DF)

So, the perimeter of ABC is three times the perimeter of DEF, and thus it's

12\cdot 3 = 36 feets

=(−4)(3.2)+(−4)(−3k)+(0.2)(9)+(0.2)(15k)

=−12.8+12k+1.8+3k

Combine Like Terms:

=−12.8+12k+1.8+3k

=(12k+3k)+(−12.8+1.8)

kvv77 [185]

Answer: Independent event

Step-by-step explanation:

When two events are independent of each other, this means that the probability that one event will occurs does not in any way affects the probability of the occurrence of the other event.

For example, card is picked at random from a deck of cards, and after putting it back,thne another card is picked at random. ​The probability of picking the cards is not affected by each other since it is put back.
