146 m²

Area of triangle:

  • 1/2 * base * height
  • 1/2 * 16 * 7
  • 56 m²

Area of upper rectangle:

  • Length * Width
  • 8 * 9
  • 72 m²

Area of bottom rectangle:

  • Length * Width
  • 6 * 3
  • 18 m²

Total area:

Answer:

146 m²

Step-by-step explanation:

Divide the figure into a triangle and 2 rectangles (see attached diagram)

<u>Formulae</u>

  • Area of a triangle = 1/2 x base x height
  • Area of a rectangle = width x length

<u>Triangle 1</u>

⇒ area = 1/2 x 16 x (6 + 9 - 4 - 4)

            = 1/2 x 16 x 7

            = 56 m²

<u>Rectangle 2</u>

⇒ area = 3 x (6 + 9)

            = 3 x 15

            = 45 m²

<u>Rectangle 3</u>

⇒ area = 5 x 9

            = 45 m²

<u>Total area</u>

⇒ Total area = triangle 1 + rectangle 2 + rectangle 3

                      = 56 + 45 + 45

                      = 146 m²

At the scene of a crime, the police have found a blood stain, a footprint, and some threads from a fabric. All are presumed to h
zubka84 [21]

Answer:

There is a 0.175% chance of finding such a person who has all three characteristics.

Out of 4,000 people, 7 people would likely to match all three characteristics.

Step-by-step explanation:

A crime has been committed and after analyzing the evidence, police has found out that:

  1. The criminal's blood type is a type found in only 10% of the population.
  2. The criminal's footprint is a size 13 men's shoe and only 7% of the population wears such shoe size.
  3. Only 25% of the population owns clothing made from a fabric that matches the thread samples found at the scene.

We required to find out the probability of selecting a random person who would match all of these characteristics.

Since it is given that the three characteristics are independent of each other then the required probability is  

P(all 3 characteristics) = P(1st characteristic)*P(2nd characteristic)*P(3rd characteristic)

P(all 3 characteristics) = (10/100)*(7/100)*(25/100)

P(all 3 characteristics) = 1750/1,000,000

P(all 3 characteristics) = 7/4000

P(all 3 characteristics) = 0.00175

P(all 3 characteristics) = 0.175%

So out of 4,000 people, 7 people would likely to match all three characteristics.

or

There is a 0.175% chance of finding such a person who has all three characteristics
