Answer:

b) stem-and-leaf-plot because it showed each value in the set of data

Step-by-step explanation:

First let's clarify the concept of median, the median is the average value of a sample of data, that is, the data of half.

Now, a histogram is a graph of frequency, therefore although it organizes the data from highest to lowest, we will see the number of times in this case the age is repeated in a certain range.

For its part, stem-and-leaf-plot shows each data of the sample in an organized way, therefore it will be easier to find the data of half.

In other words, the correct answer is b.

First we have to change rupees into paise .

[Rupees = 100paise]

Sandwiches = 1.85+1.85=370paise

Drinks = 72p+72p=144paise

Sweets = 105paise

Adding the total payment:-

370+144+105=619paise

619 paise means 6.19rupess

Hence 10-6.19=3.81rupess.

a circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle, what is the area of the shaded region

mojhsa [17]

Answer:

42.43 $cm^{2}$

Step-by-step explanation:

Given:

A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.

Question asked:

What is the area of the shaded region as shown in the figure ?

Solution:

First of all calculate area of circle and then area of rectangle:-

$Area\ of\ cirle=\pi r^{2}$

$= =\frac{22}{7} \times5\times5\\ \\ =\frac{550}{7}\\ \\=78.571$

As here length an width both are 11 cm, we can say that this is a square.

$Area\ of\ square=(Side)^{2}$

= $=11\times11=121\ cm^{2}$

Now, area of shaded region = Area of square - Area of circle

= 121 - 78.571 = 42.429 $cm^{2}$

Therefore, the area of the shaded region will be 42.43 $cm^{2}$
