Q

What is an example of a Related (Proportional) relationship?

A

studying and test score

18
Q

How are studying and test score Related (Proportional)?

A

because when people think of studying they also think of a test score

19
Q

What is an Inversely related (Inversely Proportional) relationship?

A

when 2 things have a connection to each other and one thing affects the other in an opposite way

20
Q

What happens in an Inversely related (Inversely Proportional) relationship?

A

one thing increases causing the other thing to decrease (↑,↓)

or

one thing decreases causing the other thing to increase (↓,↑)

21
Q

What is an example of an Inversely related (Inversely Proportional) relationship?

A

school grades and party time

22
Q

How are school grades and party time Inversely related (Inversely Proportional)?

A

because the more time someone spends partying, the less time they spend studying causing their grades to lower (↑,↓)

or

the less time someone spends partying, the more time they spend studying causing their grades to go up (↓,↑)

23
Q

What is an example of an Inversely related (Inversely Proportional) relationship?

A

clothes and temperature

24
Q

How are clothes and temperature Inversely related (Inversely Proportional)?

A

because as the temperature increases (gets hot), the less clothes a person wears (↑,↓)

or

as the temperature decreases (gets cold), the more clothes a person wears (↓,↑)

25
Q

What is a Reciprocal relationship?

A

when 2 things or numbers are a reciprocal/opposite of each other that equals to the number 1 when they are multiplied together

26
Q

What is another definition of a Reciprocal relationship?

A

a type of Inversely related (Inversely Proportional) relationship

27
Q

What happens in an Inversely related (Inversely Proportional) relationship?

A

one thing increases causing the other thing to decrease (↑,↓)

or

one thing decreases causing the other thing to increase (↓,↑)

28
Q

What is another thing that happens in a Reciprocal relationship?

A

a number changes into the opposite number in the form of a fraction that equals 1 when multiplied together with the original number

29
Q

What is a number example of a Reciprocal relationship?

A

2

30
Q

How can the number 2 become a reciprocal number?

A

because the number 2 in a fraction form is (2/1), the opposite of that fraction is (1/2), when 2/1 and 1/2 are multiplied it equals 1; 1/2 is the reciprocal of 2

31
Q

What is a number example of a Reciprocal relationship?

A

10

32
Q

How can the number 10 become a reciprocal number?

A

because the number 10 in a fraction form is (10/1), the opposite of that fraction is (1/10); when 10/1 and 1/10 are multiplied it equals 1; 1/10 is the reciprocal of 10

33
Q

What is an example of a Reciprocal relationship in an ultrasound scenario?

A

period and frequency

34
Q

How are Period and Frequency a Reciprocal?

A

because when the Period increases, the Frequency decreases (↑,↓)

or

when the Period decreases, the Frequency increases (↓,↑)

35
Q

What kind of graph does a Directly related (Directly Proportional) relationship produce?

A

a graph where the 2 variables have a direct relationship

36
Q

How does a Directly related (Directly Proportional) graph look like?

A

the horizontal line (x-axis line) goes side to side

and

the vertical line (y-axis line) goes up and down

(y-axis)

I———————(x-axis)

37
Q

What happens in a Directly related (Directly Proportional) graph?

A

when the x-axis increases, the y-axis increases

or

when the x-axis decreases, the y-axis decreases

38
Q

What is an example of a Directly related (Directly Proportional) graph?

A

y-axis = height in feet

x-axis = age in years

the older someone gets (x-axis) the taller they get (y-axis)

vice versa

the younger someone is (x-axis) the shorter they are (y-axis)

39
Q

What kind of graph does an Inversely related (Inversely Proportional) relationship produce?

A

a graph where the 2 variables have an inverse relationship

40
Q

How does an Inversely related (Inversely Proportional) graph look like?
