Given:

Perimeter of the figure = 18.6 inches

To find:

The length of n.

Solution:

Perimeter of the figure = 18.6 inches

Perimeter = Sum of the sides

3 + 6.3 + 4.5 + n = 18.6

13.8 + n = 18.6

Subtract 13.8 from both sides.

13.8 + n - 13.8 = 18.6 - 13.8

n = 18.6 - 13.8

n = 4.8

The length of n is 4.8 inch.

steposvetlana [31]

So first you have to multiply 21 by .1 to figure out ten percent
you then get 2.1
you add 21 and 2.1 together and get 23.1
then since you have 3 people you divide by 3 and get 7.7
therefor 7.7 is your answer

Answer:

The inter quartile range is 55

Step-by-step explanation:

Interquartile range:-

Definition:-

The inter quartile range is the difference between the upper (Q3) and lower(Q1) quartiles, and describes the middle 50% of values when ordered from lowest to highest.

Interquartile range = higher quartile - lower quartile

given data 50.25.80.10

write the ascending order 10 25 50 80

Step:-1

Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.

If the number of observations is odd, then the median is

$({\frac{n+1}{2} })^{th}$ observations

Step2:-

The median is obtained by first arranging the data in ascending or descending order and applying the following rule.

If the number of observations is even, then the median is $({\frac{n}{2} })^{th}$

$({\frac{n+1}{2} })^{th}$

In given data the number of observations is '4'(even)

If the number of observations is even, then the median is $({\frac{n}{2} })^{th}$

$({\frac{n+1}{2} })^{th}$

median is $({\frac{4}{2} })^{th}$ is 2 observations and $({\frac{4+1}{2} })^{th}$ is 2.5 observations.

so we have to select average of these two observations.

therefore the median is '3' observation

median of the given data = 50

Step:3

Interquartile range = higher quartile - lower quartile

= 80-25

=55
