LenaWriter [7]

Answer:

<h3>5 years</h3>

Step-by-step explanation:

To get the median of the ages given

2, 4, 5, 6, 7, 8, 8, 8, 0, 3, 5, 9, 1, 4, 7, 6, 1, 2, 4, 4, 8

First we will need to rearrange the median ages in ascending order (from lowest to highest)

0, 1, 1, 2, 2, 3, 4, 4, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 8, 8, 9

Next is to locate the middle value of the arranged data

(0, 1, 1, 2, 2, 3, 4, 4, 4, 4), 5, (5, 6, 6, 7, 7, 8, 8, 8, 8, 9)

The total values in both parenthesis are the same(10 in numbers) leaving 5 as the middle number.

Hence the median age of the people in the pool is 5years

The sum of three consecutive odd integers is 75. Find the integers.

makkiz [27]

Answer:

23, 25, and 27.

Step-by-step explanation:

Let the first odd integer be <em>k</em>.

Since the three numbers are consecutive odd integers, the second is given by (<em>k</em> + 2) and the third by (<em>k</em> + 4).

Their sum is 75. Hence:

$k + (k + 2) + (k + 4) = 75$

Solve for <em>k</em>. Combine like terms:

$3k + 6 = 75$

Subtract:

$3k = 69$

And divide:

$k = 23$

Therefore, the first number is 23.

In conclusion, the three consecutive, odd integers are 23, 25, and 27.
