Percentage of U.S. Population with Diagnosed Diabetes by Gender Gender Male
777dan777 [17]

Answer:

Men are also at slightly higher risk of developing diabetes than women. This may be more associated with lifestyle factors, body weight, and where the weight is located (abdominally versus in the hip area) than with innate gender differences.

Significant risk factors include:

  • older age
  • excess weight, particularly around the waist
  • family history
  • certain ethnicities
  • physical inactivity
  • poor diet

Among the US population overall, crude estimates for 2018 were:

• 34.2 million people of all ages—or 10.5% of the US population—had diabetes.

• 34.1 million adults aged 18 years or older—or 13.0% of all US adults—had diabetes

• 7.3 million adults aged 18 years or older who met laboratory criteria for diabetes were not aware of or  did not report having diabetes (undiagnosed diabetes). This number represents 2.8% of all US  adults and 21.4% of all US adults with diabetes.

• The percentage of adults with diabetes increased with age, reaching 26.8% among those aged 65 years  or older

Among US adults aged 18 years or older, age-adjusted data for 2013–2016 indicated a higher percentage of men (37.4%) than women (29.2%) had prediabetes

Step-by-step explanation:

In 2018, 34.2 million Americans, or 10.5% of the population, had diabetes.

Nearly 1.6 million Americans have type 1 diabetes, including about 187,000 children and adolescents

Of the 34.2 million adults with diabetes, 26.8 million were diagnosed, and 7.3 million were undiagnosed.

The percentage of Americans age 65 and older remains high, at 26.8%, or 14.3 million seniors (diagnosed and undiagnosed).

1.5 million Americans are diagnosed with diabetes every year.

In 2015, 88 million Americans age 18 and older had prediabetes.

Use the following functions for 10–12:
Step2247 [10]
  • h(x) = f(x) + g(x) = h(x) = 18.5x-16
  • h(x) = g(x) – f(x) = h(x) = 23.5x-40
  • h(x) = 4g(x) = h(x) = (84x-112)

<u>Step-by-step explanation:</u>

Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or f(x) = -2.5x + 12, g(x) = 21x - 28 .

10. Find h(x) = f(x) + g(x).

⇒ h(x) = f(x) +g(x)

⇒ h(x) = ( -2.5x + 12)+( 21x - 28)

⇒ h(x) = ( 21x-2.5x )+( 12 - 28)

⇒ h(x) = 18.5x-16

11. Find h(x) = g(x) – f(x).

⇒ h(x) = g(x)-f(x)

⇒ h(x) = ( 21x - 28)-( -2.5x + 12 )

⇒ h(x) = ( 21x+2.5x )+( -12 - 28)

⇒ h(x) = 23.5x-40

12. Find h(x) = 4g(x).

⇒ h(x) = 4g(x)

⇒ h(x) = 4( 21x - 28)

⇒ h(x) = (84x-112)

Find the total surface area of a cone whose radius is r/2 and slant height is 2l
Hunter-Best [27]
Total surface area of cone:  πrl + πr²

Assuming the bottom of the cone is closed.

r = r/2,  l = 2l

Total surface Area =  π*(r/2)*2l + π(r/2)²  =  πrl + πr²/4

Total Surface Area = πrl + πr²/4
