As a fraction in simplified form, 3.5 is equal to 7/2 .

But you say you want something that's repeating.  

That's a problem . . . there's no part of 3.5 that's repeating now, and if I just go ahead and write something that does repeat, my invention will change the value, and it won't be equal to 3.5 any more.

Here's one possibility, I guess: <em>3.500 000 000 000 000 000 000 . . .</em>

The zeros repeat infinitely, and no matter how many (or how few) zeros you write, the value of the number is always 3.5 and it never changes.

If it's the ' 5 ' on the end that you want to see repeating, that's actually easier to work with.  Then we have <em>3.555 555 555 555 555 555 . . .</em>

THOSE fives really do keep repeating and never end, and that number is equal to <em>(3 and 5/9)</em> or<em> (32/9) </em>.

The mean age of 11 women in an office is 31 years old.
BlackZzzverrR [31]

Answer: 30.2

Explanation:

The mean is calculated by taking the sum of the values and dividing by the count.

For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:

186

6

=

31

And we can do the same for the men:

116

4

=

29

And now we can combine the sum and count of the men and women to find the mean for the office:

186

+

116

10

=

302

10

=

30.2

The monthly worldwide average number of airplane crashes of commercial airlines is 3.5. What is the probabil- ity that there wil
Levart [38]

Answer:

Step-by-step explanation:

We would apply the formula for poisson distribution which is expressed as

P(x = r) = (e^- µ × µ^r)/r!

Where

µ represents the mean of the theoretical distribution.

r represents the number of successes of the event.

From the information given,

µ = 3.5

a)

For the probability that there will be at least 2 such accidents in the next month, it is expressed as

P(x ≥ 2) = 1 - P(x < 2)

P(x < 2) = P(x = 0) + P(x = 1)

Therefore,

P(x = 0) = (e^- 3.5 × 3.5^0)/0!

P(x = 0) = (e^- 3.5 × 1)/1

P(x = 0) = 0.03

P(x = 1) = (e^- 3.5 × 3.5^1)/1!

P(x = 1) = (e^- 3.5 × 3.5)/1

P(x = 1) = 0.11

P(x < 2) = P(x = 0) + P(x = 1) = 0.03 + 0.11 = 0.14

P(x ≥ 2) = 1 - 0.14 = 0.86

b)

For the probability that there will be at most 1 accident in the next month, it is expressed as

P(x ≤ 1) = P(x = 0) + P(x = 1)

P(x = 0) = 0.03

P(x = 1) = 0.11

P(x ≤ 1) = 0.03 + 0.11 = 0.14
