Answer:

395.841

Step-by-step explanation:

surface area = 2πrh + 2πr²

where r = 7 m radius

           h = 2 m

plugin values into the formula

surface area = 2πrh + 2πr²

                     = 2π (7) 2  +  2π (7)²

                     = 87.965  +  307.867

                     = 395.841 m²

Answer:

395.841 m²

Step-by-step explanation:

surface area = 2πrh + 2πr² and r = 7 m radius

h = 2 m

Plugin

 2π (7) 2  +  2π (7)²

multiply into itself than add

87.965  +  307.867

add

395.841 m²

Therefore your answer would be 395.841 m²

Angles A and B are complementary. Angle A measures 3x + 10
degrees and angle B measures 2x + 20 degrees. What is the value of
x?

Answers

Answer:

x = 12

Step-by-step explanation:

Lets set up the equation!

Complementary angles equal 90 degrees.

2x + 20 + 3x + 10 = 90

Now lets combine the like terms!

2x + 3x 20+ 10

5x +30 = 90

Now subtract 30 from both sides!

5x = 60

Divide each side by 5

x = 12

D 115

Answers

i THINK it’s D cuz the other side would also be 65 and it’s a 180 line in total

The measure of x is 115° from the given parallel lines. Therefore, option D is the correct answer.

What are angles of parallel lines?

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

Let the interior alternate angle to 65° be y.

Now, y=65°  (Alternate interior angles are equal)

Here, y°+x°=180° (Adjacent angles)

65°+x°=180°

x°=115°

Therefore, option D is the correct answer.

As part of a study of the association between smoking and risk of squamous cell carcinoma, a logistic regression model was estimated as:

logit(probability of having squamous cell carcinoma) = -4.84 + 4.6*(SMOKER)

where SMOKER=0 for non-smoker and 1 for smoker. What is the predicted probability of a smoker having squamous cell carcinoma?

Answers

Answer:

0.44

Step-by-step explanation:

Given the estimated logistic regression model on risk of having squamous cell carcinoma

-4.84 + 4.6*(SMOKER)

SMOKER = 0 (non-smoker) ; 1 (SMOKER)

What is the predicted probability of a smoker having squamous cell carcinoma?

exp(-4.84 + 4.6*(SMOKER)) / 1 + exp(-4.84 + 4.6*(SMOKER))

SMOKER = 1

exp(-4.84 + 4.6) / 1 + exp(-4.84 + 4.6)

exp^(-0.24) / (1 + exp^(-0.24))

0.7866278 / 1.7866278

= 0.4402863

2x+2x+60=180 because the angles have to add up to 180

So you have

Answer:

X=30

Step-by-step explanation:

It is a equilateral triangle so all side are the same

You would add the x's so it would be 4x + 60 = 180

4x + 16y = -19

Answers

Answer:

No solution.

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Algebra I

Solving systems of equations using substitution/eliminationSolving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

4x + 16y = -19

-2x - 8y = 10

Step 2: Rewrite systems

-2x - 8y = 10

Add 8y to both sides:                    -2x = 8y + 10Divide -2 on both sides:                x = -4y - 5

Step 3: Redefine systems

4x + 16y = -19

x = -4y - 5

Step 4: Solve for y

Substitution

Substitute in x:                         4(-4y - 5) + 16y = -19Distribute 4:                              -16y - 20 + 16y = -19Combine like terms:                -20 ≠ -19

Here we see that -20 does not equal -19.

∴ This systems of equations has no solution

Step 5: Graph

Check the systems.

If the quadratic equation can be divided by a-2 the first part is:

Now to get a², the a must be multpilied by itself. So

(a-2)(a)

To get -10, -2 must be multiplied by 5. So:

Which statement is true about the line?

A)The line falls from left to right.

B)The y-intercept is at (-7,0)

C)The equation of the line is y= 4/3x+7

D)The equation of the line is y= -4/3x+7

Answers

Answer:

A

Step-by-step explanation:

Since the slope is negative the line falls left to right.

The equation of the line falls from left to right.

What is a slope?

The slope of a line, commonly referred to as its gradient, in mathematics is a numerical representation of the steepness and direction of the line.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given, the y-intercept of a line is - 7 and the slope of the line is -4/3.

And the standard form of the slope-intercept form:

y = mx + b,

where m is the slope and b is the y-intercept.

Here, m = -4/3 and b = -7.

Substituting the above values to the standard slope-intercept form,

y = (-4/3)x + (-7)

y = (-4/3)x -7

And the line falls from left to right.

Therefore, the line falls from left to right.

please help!! this is due at 3 i don’t know how to do this one

Answers

Answer: y = 1/3x + 2

Step-by-step explanation:

You basically use the rise over run method and see the slope increases by 1/3 ( it comes up one and goes right 3 ) and it starts at 2

y = 1/3x + 2

Using Rise/Run — rise is the line rising, like going up, and run is the line running, like running to the side. It rises by 1, then runs by 3. That’s how you get 1/3x. Then, you find the Y variable, which is 2, and that it how you get the answer.

The scores on a standardized test are normally distributed. If a random sample of standardized test scores is taken and the confidence interval is (92.3,120.7), what is the sample mean x¯?

Answers

Answer: 106.5

Step-by-step explanation:

We know that, Confidence interval for population mean is given by :-

( Sample mean - Margin of error ,  Sample mean + Margin of error)

Given: confidence interval is (92.3, 120.7).

i.e.  Sample mean - Margin of error = 92.3   (i)

Sample mean + Margin of error = 120.7  (ii)

Adding (i) and (ii) , we get

2( Sample mean ) = 213

⇒ Sample mean = 106.5

Hence, the sample mean [tex](\overline{x})[/tex] = 106.5
