Here is some information about 26 houses.a,b and c are all different numbers.Number of bedrooms:1,2,3,4,5.Number of houses:7,a,b

kkurt [141]

Answer:

$[a,b,c]=[4,2,5]$ or $[a,b,c]=[2,4,5]$

Step-by-step explanation:

Given

$\begin{array}{cccccc}{Bedroom} & {1} & {2} & {3} & {4} & {5} \ \\ {Houses} & {7} & {a} & {b} & {c} & {8} \ \end{array}$

$n = 26$

$Median = 3.5$

Required

Find a, b and c

Median is calculated as:

$Median = \frac{n+1}{2}$

$Median = \frac{26+1}{2}$

$Median = \frac{27}{2}$

$Median = 13.5th$

This means that the median is the average of the 13th and 14th item.

$\begin{array}{cccccc}{Bedroom} & {1} & {2} & {3} & {4} & {5} \ \\ {Houses} & {7} & {a} & {b} & {c} & {8} \ \end{array}$

Since the median is $Median = 3.5$ (average of 3 and 4),

and:

$3 \to b \to 13$

$4 \to c \to 14$

This implies that c begins at 14

So, the number of houses bedrooms 4 and 5 is:

$c + 8 = 26 - 14 +1$

$c + 8 = 13$

$c = 5$

Also

$7 + a + b + c + 8 = 26$ ---- sum of total frequency

$a + b + c = 26 - 7 - 8$

$a + b + c = 11$

Substitute $c = 5$

$a + b + 5 = 11$

$a + b = 11 - 5$

$a + b = 6$

Since a, b and c are different, then

a and b cannot be 5 because $c = 5$

a and b cannot be 3 because $a = b =3$

$b \ne 0$ because b ends at 13

a

So, possible sets are:

$[a,b]=[2,4]$

$[a,b]=[4,2]$

Include c, we have:

$[a,b,c]=[4,2,5]$ or $[a,b,c]=[2,4,5]$

Sahira chooses a random sample from the library and records the type of books in the chart below.

The last option c is right because each book selected represents the sample from the population of full library books.

We have given that,

Sahira chooses a random sample from the library and records the type of books in the chart below.

Type of Book Number

Fantasy 10

Literature 25

Children’s 4

Nonfiction 11

t, showing the distribution of the number of books in a library.

Also given that Sahira chooses a random sample from the library and records the type of books in the chart below.

Sahira's sample can be said to be representative because given that books are taken at random.

So just because books literature more we cannot say it is not representative II option is not right, because each book was not chosen uniquely, just random books were drawn.

<h3>What is the population?</h3>

A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time.

The last option c is right because each book selected represents the sample from the population of full library books.
