Answer 1

Answer:

4, -5)

A trisection point on a line segment trisects that line segment into three equal parts.

Here,

1 : 2

A •------------•----------------------------• B

C

Given that,

A = (5, -3)

B = (2, -9)

C = (x, y)

Which means, The point c divides the line segment in the ratio 1 : 2 which is m : n

Using the section formula, we can find the coordinate of the point C,

⇒ Cₓ = ( mx₂ + nx₁ ) / (m + n)

⇒ Cₓ = (1 × 2 + 2 × 5) / (2 + 1)

⇒ Cₓ = (2 + 10) / 3

⇒ Cₓ = 12 / 3

⇒ Cₓ = 4

Here, We got the abscissa of the point C to be 4.

Let us find the ordinate now,

⇒ Cᵧ = ( my₂ + ny₁ ) / (m + n)

⇒ Cᵧ = ( 1 × -9 + 2 × -3 ) / (1 + 2)

⇒ Cᵧ = ( -9 - 6 ) / 3

⇒ Cᵧ = -15/3

⇒ Cᵧ = -5

So, we got the ordinate to be -5.

Hence, The point C is (4, -5)

Note:-

Abscissa = x

Ordinate = y

Coordinate = (Abscissa, Ordinate

Answer 2

The double bar graph represents the number of people who like watching & participating in different sports. It can be obtained that most of the people like watching and participating in cricket while the least number of people like athletics.

The double bar graph represents the number of people who like watching & participating in different sports. It can be obtained that most of the people like watching and participating in cricket while the least number of people like athletics.ii) From the double graph, it can be observed that the bar representing the number of people who like watching & participating in cricket is the tallest among all the bars. Hence, cricket is the most popular sport.

Hence, cricket is the most popular sport.iii) The bars representing watching sport are longer than the bars representing participation in sports. Hence, watching different types of sports is more preferred than participating in sports.
