Vlad [161]

Answer:

Both the mean and median and they both gives a measure of 17

Step-by-step explanation:

Given the data about the ages of 7 people :

17,20,22,12,15,12,21

Ordered data: 12, 12, 15, 17, 20, 21, 22

To find the median :

Median = 1/2 * (n+1)th term

n = number of observations = 7

Median = 1/2(7+1)th term

Median = 1/2 *8 = 4th term = 17

Mean = Σx / n = (sum of ages) / number of observations

Mean = 119 / 7 = 17

Igoryamba
<h2>The length of the yard was 563 yards.</h2>

Step-by-step explanation:

Given,

The area of the yard = 6,756 square yards and

The width of the yard (b) = 12 yards

To find, the length of the yard (l) = ?

We know that,

Area of the rectangle =  Length(l) × Breadth(b)

⇒ l × 12 = 6,756

⇒ l =\dfrac{6,756}{12}

⇒ l = 563 yards

Thus, the length of the yard was 563 yards.
