Answer:

Probability [selected donuts a jelly-filled donut] = 2 / 23

Step-by-step explanation:

Given:

Total number of donuts = 92

Number of jelly-filled donuts = 8

Find:

Probability [selected donuts a jelly-filled donut]

Computation:

Probability [selected donuts a jelly-filled donut] = Number of jelly-filled donuts / Total number of donuts

Probability [selected donuts a jelly-filled donut] = 8 / 92

Probability [selected donuts a jelly-filled donut] = 2 / 23

Answer:

○ [tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]

Step-by-step explanation:

[tex]\displaystyle \boxed{f(x) = 10sin\:(\frac{\pi}{2}x + \frac{\pi}{2}) + 10} \\ \\ y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-1} \hookrightarrow \frac{-\frac{\pi}{2}}{\frac{\pi}{2}} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]

OR

[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 10 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{4} \hookrightarrow \frac{2}{\frac{\pi}{2}}\pi \\ Amplitude \hookrightarrow 10[/tex]

The cosine graph in the photograph on the right is the OPPOCITE of the cosine graph in the photograph on the left, and the reason for this is because of the negative inserted in front of the amplitude value. Whenever you insert a negative in front of the amplitude value of any trigonometric equation, the whole graph reflects over the midline. Keep this in mind moving forward. Now, with all that being said, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

**Moreover, both graphs have the same maximum and minimum value, but we are looking for the equation that will not reflect over the midline of [tex]\displaystyle y = 10,[/tex]which means we do NOT want a negative in front of the amplitude value, therefore we have this equation:

[tex]\displaystyle f(x) = 10cos\:\frac{\pi}{2}x + 10[/tex]

If you are having trouble figuring out which graph is which, just remember that the parent function of [tex]\displaystyle y = cos\:x[/tex]never touches the origin unless it shifts one unit south or gets reflected from somewhere. In this case, the photograph on the left touches the origin because of a reflection [negative symbol], therefore the photograph on the right matches the equation selected.

I am delighted to assist you at any time.

The correct function is,

⇒ y = 10 cos (π/2x) + 10

A relation between a set of inputs having one output each is called a function.

Given that;

A cosine function has a period of 4.

Since, The period is 4.  

Hence, The relationship between period and b (the coefficient of the independent variable of the cosine function) is, (period) =(2π/b).  

Hence, We get;

⇒ 4b = 2π

⇒ b = 2π/4

⇒ b = π/2

So, Now our equation y = a cos (bx) + c becomes as;

⇒ y = 10 cos (π/2x) + 10

Thus, The horizontal center line of this cosine curve is y = 10.  The maximum value of the curve is 20, which is 10 + 10, and the minimum value is 0, which is 10 - 10.

Answer:

x=110°

Step-by-step explanation:

Sum of angles in a quadrilateral = 360°

360° - 128° - 40° - 82° = 110°

Answer:

x = 110

Step-by-step explanation

The sum of the interior angles of a quadrilateral = 360°

Sum the given angles and equate to 360

82 + 40 + 128 + x = 360

250 + x = 360 ( subtract 250 from both sides )

x = 110

Answer:

21 + 19 + x

40 + x

Step-by-step explanation:

well you would just add up 21 + 19 + x. that would be 40 + x. That would be the number of miles

Answer:

14

Step-by-step explanation:

Convert 21 to a fraction: 21/1

2x21= 42

3x1= 3

42/3= 14

Answer:

The option which is the closest to the measure of ∠A is 74°

Step-by-step explanation:

The question is answered using the options provided by a similar question from an online source

When tan A = (7/2), we have;

The trigonometric ratio for the tangent of an angle is given as follows;

[tex]tan\angle A = \dfrac{Opposite \ leg \ length}{Adjacent \ Leg \ length} = \dfrac{sin \angle X}{cos\angle X}[/tex]

tan A = (7/2) = 3.5

sin(30°) = 1/2, cos(30°) = (√3/2)

sin(60°) = (√3/2), cos(60°) = (1/2)

sin(45°) = cos(45°) = (√2/2)

tan(30°) = (1/2)/(√3/2) = (√3)/3

tan(45°) = 1

tan(60°) = (√3/2)/(1/2) = √3

The tangent of an angle is increasing as we move from 0° to 90°

Therefore, given that tan A = 7/2 > tan 60° = √3, we have;

∠A > 60°

The option (the options obtained from an online source are; 15°, 39°, 58°, and 74°) which is the closest to the measure of ∠A is 74°.

y-intercept is -2

Step-by-step explanation:

put into slope-intercept form which is y = mx + b where 'm' is slope and 'b' is the y-intercept

12x + 4y = -8

4y = -12x - 8

y = -12/4x - 8/4

Answer: 20x-6 = 34

Step-by-step explanation:

Given: The length of rectangle is represented by 8x - 3.

The width of the rectangle is represented by 2x.

The perimeter is 34 inches.

Perimeter of rectangle = 2 (length + width)

Perimeter of rectangle = 2 (8x-3+2x)

Perimeter of rectangle = 2 (10x-3)

Perimeter of rectangle = 20x-6

Thus , the required equation that represent the perimeter: 20x-6 = 34
