Find the value of 40% of 1KM (in m)

labwork [276]

40% of 1 km in meters is 400 meters

<h3>What is percentage :</h3>

Percentage simply means per 100. Percentage can be express as decimal or fraction.

For example 25% of 80 can be found as follows:

25 / 100 × 80 = 2000 / 100 = 20

From the example, 25% of 80 is 20 .

Therefore, 40% of 1 km(m) can be found as follows:

Let's convert km to metres.

1000m = 1km

40% of 1000

40 / 100 × 1000 = 40000 / 100 = 400metres

Therefore, 40% of 1 km in meters is 400 meters

Find the interquartile range of the data.

likoan [24]

The answer is 14. Here is how I work it out.

First we are going have to identify quartile 1 and quartile 3.

So after putting the numbers in order from least to greatest mark the number with a half way point.

This is optional but it will help us spot the sections better.

31,33,35,41,43,|46,48,49,49,50

Next put parentheses around the remaining groups of numbers.

(31,33,35,41,43,)|(46,48,49,49,50)

For the next step we have to find the median of each group.

(31,33,35,41,43,)|(46,48,49,49,50)

The median of each group, are called the quartiles, the median of the lower half is quartile 1, and the median of the upper half is quartile 3.

Now subtract quartile 1 from quartile 3.

49 – 35 = 14

So the interquartile range of this data set is 14.

|x|, if x=10; .3; 0; −2.7; −9

alekssr [168]

Answer:

For $\left | x \right |$ we will have positive values only.

$\left | -2.7 |\right =2.7$

$\left | -9 |\right =9$

Rest are positive so will give positive values out of the modulus function.

Step-by-step explanation:

The absolute value of any number is its positive value only.

As for example $(-2.7)$ and $(2.7)$ both are having equal distance from $0$ in a number line, one on the left other on the right side of the number line but are equidistant from $0$ .

So absolute value of a number is its distance on number line from reference point $0$ .

One by one we will work with all of our question.

$\left | 10 |\right =10$

$\left | 0.3 |\right =0.3$

$\left | 0 |\right =0$

$\left | -2.7 |\right =2.7$

$\left | -9 |\right =9$

So we have to take the positive number out of the modulus function that is also called absolute value.
