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.

Answer:

Step-by-step explanation:

\text{\color{blue}{100\%} represents the \color{blue}{starting balance}: \color{blue}{\$50}.}

100% represents the starting balance: $50.

Method 1

Express the ending balance as a percentage of the starting balance:

\frac{\color{darkviolet}{\$50.50}}{\color{blue}{\$50}}=

$50

$50.50

\,\,1.01

1.01

1.01\times100=

1.01×100=

\,\,\color{darkviolet}{101\%}

101%

\text{Subtract the starting \color{blue}{100\%} to get the \color{green}{percent interest}:}

Subtract the starting 100% to get the percent interest:

\color{darkviolet}{101\%}-\color{blue}{100\%}=

101%−100%=

\,\,\boxed{\color{green}{1\%}}

A train travels from station A to C having distance of 285 miles in 6 hours. During the journey, it reaches intermediate station

Nesterboy [21]

Answer:

Distance between B and C = $3\times 55=165miles$

Step-by-step explanation:

Let the time taken to reach from station A to B be x hr

Let the time taken to reach from station B to C be y hr

Given total time from station A to C be 6 hr

∴ x + y = 6

⇒ y = 6 - x → (1)

Also total distance given is 285 miles

As $Distance=Speed\times Time$

∴ distance travelled between station A and B

= $40\times xmiles$

distance travelled between station B and station C

= $55\times ymiles$

So, 40x + 55y = 285

⇒ 40x + 55(6 -x) = 285 (From 1)

=> 40x + 330 - 55x = 285

=> -15x = 285 - 330

=> -15x = -45 ⇒ x=3

gives y = 6-3 = 3 hours

Distance between B and C = $3\times 55=165miles$

What is the equation of the line in slope-intercept form?

xxMikexx [17]

The equation for this line in slope-intercept form is, y=3/5x+3 since 3 is the y-intercept and 3/5 is the slope. If you have any questions about this or anything else let me know! :)
