Question

b. PQR is a Triangle, right angle at P. If PQ=10 cm and
c. Find the mean, mode and median of the given data
6, 15, 120, 50, 100, 80, 10, 15, 8, 10, 15
The area of a square park is the same as of a recta
the square park is 60 m and the length of the rect
breadth of the rectangular park.​

Answer 1

Answer:

Solution1 :

Let the RQ be x cm,

In right angle triangle PQR,

h^2\ =\ b^2+p^2h

2

= b

2

+p

2

QR^2\ =\ PQ^2\ +PR^2\QR

2

= PQ

2

+PR

2

x^2=\ \left(10\right)^2+\left(24\right)^2x

2

= (10)

2

+(24)

2

x^2\ =\ 100\ +576x

2

= 100 +576

x\ =\ \sqrt{100+576}x =

100+576

x\ =\ \sqrt{676}x =

676

x = 26 cm

Thus, the length of QR is 26cm.

The Answer will right

Answer 2

Explanation:

Mean = total data ÷ number of data

=(15 + 120 + 50 + 100 + 80 + 10 + 15 + 8 + 10 + 15)÷10

= 423 ÷ 100

= 4.23

Mode = most repeated data

= 15

Median

Arrange the data in ascending order

8 10 10 15 15 15 50 80 100 120

Find the middle number

(15 + 15) ÷ 2

= 15
