Answer:

  • 0.25 →→→→ The probability that a person of age group 25-35 years has a hemoglobin level less than 9.
  • 0.47 →→→→ The probability that a person older than 35 years has a hemoglobin level less than 9.
  • 0.28 →→→→ The probability that a person older than 35 years has a hemoglobin level between 9-11.
  • 0.50 →→→→ The probability that a person younger than 25 years has a hemoglobin level above 11.

Step-by-step explanation:

<u>Tile 1:</u>

The probability that a person older than 35 years has a hemoglobin level less than 9.

Let A denotes the event that the age of a person is above 35 years.

Let B denote the event that the hemoglobin level is less than 9.

Then A∩B denote the event that a person above 35 years has hemoglobin less than 9.

Let P denote the probability of an event.

Hence, we are asked to find:

P(B|A)

We know that:

P(B|A)=\dfrac{P(A\bigcap B)}{P(A)}\\\\\\P(B|A)=\dfrac{\dfrac{76}{429}}{\dfrac{162}{429}}\\\\\\P(B|A)=\dfrac{76}{162}\\\\P(B|A)=0.47

<u>Tile 2:</u>

The probability that a person younger than 25 years has a hemoglobin level above 11.

Let A denotes the event that the age of a person is less than 25 years.

Let B denote the event that the hemoglobin level is more than 11.

Then A∩B denote the event that a person below 25 years has hemoglobin more than 11.

Let P denote the probability of an event.

Hence, we are asked to find:

P(B|A)

We know that:

P(B|A)=\dfrac{P(A\bigcap B)}{P(A)}\\\\\\P(B|A)=\dfrac{\dfrac{69}{429}}{\dfrac{139}{429}}\\\\\\P(B|A)=\dfrac{69}{139}\\\\P(B|A)=0.50

<u>Tile 3:</u>

The probability that a person of age group 25-35 years has a hemoglobin level less than 9.

Let A denotes the event that the age of a person is of age group 25-35 years.

Let B denote the event that the hemoglobin level is less than 9.

Then A∩B denote the event that a person between 25-35 years has hemoglobin less than 9.

Let P denote the probability of an event.

Hence, we are asked to find:

P(B|A)

We know that:

P(B|A)=\dfrac{P(A\bigcap B)}{P(A)}\\\\\\P(B|A)=\dfrac{\dfrac{32}{429}}{\dfrac{128}{429}}\\\\\\P(B|A)=\dfrac{32}{128}\\\\P(B|A)=0.25

<u>Tile 4:</u>

The probability that a person older than 35 years has a hemoglobin level between 9-11.

Let A denotes the event that the age of a person is above 35 years.

Let B denote the event that the hemoglobin level between 9-11.

Then A∩B denote the event that a person above 35 years has hemoglobin between 9-11.

Let P denote the probability of an event.

Hence, we are asked to find:

P(B|A)

We know that:

P(B|A)=\dfrac{P(A\bigcap B)}{P(A)}\\\\\\P(B|A)=\dfrac{\dfrac{46}{429}}{\dfrac{162}{429}}\\\\\\P(B|A)=\dfrac{46}{162}\\\\P(B|A)=0.28

Older then 35, hemo. less then 9.....76/162 = 0.47
younger then 25, hemo. above 11....69/139 = 0.50
25-35 age group, hemo. less then 9...32/128 = 0.25
older then 35, hemo. between 9 and 11...46/162 = 0.28

6 Paul runs 1.5 km on the bearing 127°. a Draw a diagram of the situation. b How far east is Paul from his starting point? ( How
GenaCL600 [577]

By running in a bearing of 127°, Paul motion is in the south eastern direction.

Correct responses:

a. Please find attached the required diagram created with MS Visio

b. Paul's distance travelled east is approximately 11.98 km

  • Paul's distance travelled south is approximately 0.903 km

<h3>Method used for diagram and for the distance calculation</h3>

Given:

The distance Paul runs = 1.5 km

The bearing Paul is running = 127°

a. The bearing of path Paul runs, 127°, is the angle measured in the clockwise direction relative to the northern direction

Please find attached the diagram representing the situation, created with MS Visio.

b. Paul's distance travelled east relative to the starting point is given by the component of Paul's path in the x-axis direction which is found as follows;

  • Paul's distance east =  15 km × cos(37°) ≈ <u>11.98 km</u>

Pau's distance travelled in the south direction relative to the starting point

is given by the vertical distance travelled relative to the x-axis, which is

given as follows;

Distance Paul travels south = 1.5 km × sin(37°) ≈ <u>0.903 km</u>

Need help with number 60 I’m really bad at problem solving
loris [4]

Answer:

okay so, i had a problem like this one and hated it, so ill try to help you out here

Step-by-step explanation:

If it is 81 all together it is safe to say the length and width is nine, making one mat six by 3, the little square being 3 by 3,

so the area of one mat would be six times three = 18

and if the width is 3, the length would be 6, unless it is cut in half, which we can assume it is not.

I hope this helps!
