Answer:

8.9443

Step-by-step explanation:

d = √((x2-x1)2 + (y2-y1)2)

Step by step procedure:

Find the difference between coordinates:

(x2-x1) = (-9 - -1) = -8

(y2-y1) = (2 - -2) = 4

Square the results and sum them up:

(-8)2 + (4)2 = 64 + 16 = 80

Now Find the square root and that's your result:

Exact solution: √80 = 4√5

Approximate solution: 8.9443

4 letters are typed, without repetition. What is the probability that all 4 will be vowels? Write your answer asa percent. Round
Marysya12 [62]

There are 26 letters in the alphabet, 5 are vowels, therefore, the probability of choosing a vowel the first time is:

\frac{5}{26},

and the second time is:

\frac{4}{25}\text{.}

Continuing with this reasoning, we get that the probabilities each time are:

\frac{5}{26},\frac{4}{25},\frac{3}{24},\frac{2}{23}\text{.}

Finally, the probability that you get all vowels is the product of the probabilities:

\frac{1}{2990}\text{.}

Writing the above result as a percentage we get:

0.033\%.

Answer:

0.033\%\text{.}
