Answer: 14.73

Step-by-step explanation:

The given triangle is a right angle triangle.

EF^2 + DF^2 = ED^2

The hypotenuse is |ED| while the two shorter legs are |EF| and |DF|.

We can then apply the Pythagoras Theorem to find the length of EF.

(EF)^2 + (DF)^2 = (ED)^2

(EF)^2 + (12)^2 = (19)^2

(EF)^2 + 144 = 361

(EF)^2 = 361 - 144

(EF)^2 = 217

EF = 14.73

Answer:

x^2 - 6x - 4 = x^2 - 6x + 9 - 13 = x^2 - 2.x.3 + 3^2 - 13

= (x-3)^2 - 13

(m = -3 and n = -13)

julsineya [31]

Answer:

the probability that the ball falls into a redred ​slot is 0.4996

Step-by-step explanation:

The question is not correct right question is:

A carnival roulette wheel contains 2224 slots numbered​ 00, 0,​ 1, 2,​ 3, ..., 2222. 1111 of the slots numbered 1 through 2222 are colored​ red, and 1111 are colored black. The 00 and 0 slots are uncolored. The wheel is​ spun, and a ball is rolled around the rim until it falls into a slot. What is the probability that the ball falls into a redred ​slot?

Given that:

The carnival roulette wheel has 2224 slots numbered​ 00, 0,​ 1, 2,​ 3, ..., 2222.

1111 of the slots are colored red while 1111 of the slots are uncolored. The remaining slots 00 and 0 are uncolored.

Therefore, the total number of possible outcome is 2224. Probability is the ratio of number desired outcome to total number of possible outcome.

For, the probability that the ball falls into a redred ​slot, the desired outcome is 1111(i.e number of red slot)

Therefore, the probability that the ball falls into a redred ​slot = 1111/2224 = 0.4996
