Answer:
1.05
Step-by-step explanation:
Waist to Hip Ratio would be the ratio of the waist measurement to the hip measurement.
The waist measurement is 42 inches and the hip measurement is 2 less; this makes the hip measurement 42-2 = 40 inches.
This makes the WHR 42/40 = 1.05.
The ratio of the waist measurement to hip measurement is [tex]\boxed{\bf 1.05}[/tex] and he is in the high risk of cardiovascular problems.
Further explanation:
The ratio is a quantitative relation between two amounts.
The ratio can be expressed in the form of [tex]a:b[/tex], where [tex]a[/tex] and [tex]b[/tex] are the real numbers.
The ratio [tex]a:b[/tex] can be written in the form of fraction as [tex]\frac{a}{b}[/tex] where [tex]a[/tex] is divided by [tex]b[/tex].
Given:
Kevin’s waist measurement is [tex]42\text{ inches}[/tex] and hip measurement is [tex]2\text{ inches}[/tex] less than the waist measurement.
Calculation:
Step 1:
First we have to find Kevin’s hip measurement.
Kevin’s hip measurement is [tex]2\text{ inches}[/tex] less than the waist measurement which is [tex]42\text{ inches}[/tex].
Therefore, subtract the value [tex]2\text{ inches}[/tex] from [tex]42\text{ inches}[/tex] to obtain the hip measurement.
It can be mathematically expressed as follows:
[tex]\begin{aligned}\text{Hip measurement}&=42-2\\&=40\end{aligned}[/tex]
Step 2:
Now, we calculate Kevin’s WHR.
The ratio of waist measurement to hip measurement denoted as “WHR”.
The value of WHR can be expressed as follows:
[tex]\boxed{\text{WHR}=\dfrac{\text{Waist measurement}}{\text{Hip measurement}}}[/tex] …… (1)
Substitute the value of waist measurement and hip measurement in the equation (1).
[tex]\begin{aligned}\text{WHR}&=\dfrac{42}{40}\\&=\dfrac{21}{20}\\&=1.05\end{aligned}[/tex]
The value of WHR is [tex]1.05[/tex].
The waist to hip ratio (WHR) is used to predict the cardiovascular problems in both men and women.
The ratio should not be greater than [tex]1[/tex] otherwise the person would be considered in the high risk of the cardiovascular problems.
The waist to hip ratio (WHR) of Kevin is greater than [tex]1[/tex].
Therefore, Kevin is in the high risk of cardiovascular problems.
Thus, the ratio of the waist measurement to hip measurement is [tex]\boxed{\bf 1.05}[/tex] and he is in the high risk of cardiovascular problems.
