Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The diagram refers the angle bisector theorem.

Hence using this theorem in our given diagram:

$\frac{LM}{LN}=\frac{x}{ON}$

$\frac{18}{10}=\frac{x}{4}$

Cross multiplying,

$x=4*1.8 = 7.2$

Hence the answer is 7.2 : Answer (A)

Hope it will help :)

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.

In right triangle LMN, L and M are complementary angles and sin(L) is 19/20. What is cos(M).

Juliette [100K]

Option A:

$$\cos M=\frac{19}{20}$

Solution:

The image of the triangle is attached below.

Given data:

$$\sin L=\frac{19}{20}$

Using trigonometric ratio formulas,

$$\sin L=\frac{\text { Opposite side of } L}{\text { Hypotenuse }}$

$$\sin L=\frac{MN}{LM}$

So, MN = 19 and LM = 20

Using Pythagoras theorem,

In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.

$LM^2=LN^2+MN^2$

$20^2=LN^2+19^2$

$400=LN^2+361$

Subtract 361 from both sides,

39 = LN²

Taking square root on both sides,

$LN=\sqrt{39}$

$$\cos \theta=\frac{\text { Adjacent side of } \theta}{\text { Hypotenuse }}$

$$\cos M=\frac{\text { Adjacent side of } M}{\text { Hypotenuse }}$

$$\cos M=\frac{MN}{LM}$

$$\cos M=\frac{19}{20}$

Hence option A is the correct answer.

Assume that there are 56 students in this class. what is the probability that at least two students share a? birthday

navik [9.2K]

P(at least 2 students have the same birthday)= 1- P(no 2 students have the same birthday)

Because P(A)=1-P(A'), where A is an event, and A' the complement of that event.

P(no 2 students have the same birthday)=

$\frac{365}{365}* \frac{364}{365}*\frac{363}{365}*\frac{362}{365}*... \frac{310}{365}$

think of the problem as follows. We have an urn of balls, numbered from 1 to 365 (the number of the days of the year.

What is the probability of picking 56 different numbered balls, with replacements?

The first one can be any of the 365

the second any of 364 (since one selection has already been made)

the third any of the 363
.
.
and so on

the 56th selection is one of 310 left

Answer:

$\frac{365}{365}* \frac{364}{365}*\frac{363}{365}*\frac{362}{365}*... \frac{310}{365}$

Rearrange y= -3/4x + 2 in standard form with a positive lead to coefficient

Goshia [24]

Answer:

Step-by-step explanation:

$y=-\frac{3}{4} x+2\\add\frac{3}{4} x to both sides\\y+\frac{3}{4} x=-\frac{3}{4}x+\frac{3}{4} x+2\\y+\frac{3}{4}x=2\\\frac{3}{4} x+y=2$

Please mark me as brainliest!
