vichka [17]

Answer:

40.53%

Step-by-step explanation:

$Percentage Increase = \frac{New Value - Old Value}{Old Value}\times100$

Here, New Value = 960÷100,000

Old Value = 190÷ 100,000

∴ $Percentage Increase = \dfrac{\frac{960}{100,000} - \frac{190}{100 ,000} }{\frac{190}{100,000}}\times100$

⇒ Percentage Increase = 40.53%

Thus, percent increase in the male incarceration rate during given period is 40.53%.
