A carnival ride is in the shape of a wheel with a radius of 25 feet. The wheel has 20 cars attached to the center of the wheel.

What is the central angle, arc length, and area of a sector between any two cars? Round answers to the nearest hundredth if applicable. You must show all work and calculations to receive credit. (10 points)

Centre angle will be 360° as its totally a circle.

  • radius=r=25ft

Angle between two cars=360/20=18°

  • Arc length=L

\\ \sf\longmapsto L=\dfrac{\theta}{360}(2\pi r)

\\ \sf\longmapsto L=\dfrac{18}{360}(2\pi(25))

\\ \sf\longmapsto L=\dfrac{1}{20}(50\pi)

\\ \sf\longmapsto L=2.5\pi ft

Now

Area be A

\\ \sf\longmapsto A=\dfrac{1}{2}Lr^2

\\ \sf\longmapsto A=\dfrac{1}{2}(2.5\pi)(25)^2

\\ \sf\longmapsto A=625(2.5)\pi\dfrac{1}{2}

\\ \sf\longmapsto A=1562.5\pi/2

\\ \sf\longmapsto A=781\pi ft^2=

Find the mean, median, mode, and standard
Veronika [31]

Answer:

Step-by-step explanation:

mean = sum of data / no of data

20 + 58 + 74 + 77 + 77 + 85 + 86 + 90 + 95 + 98 / 10

760 / 10

76

to find median u should arrange the data from ascending to descending order.

since the given data is already arranged u dont need to change.

median = (N + 1)/2     (N means no of data)

=10 + 1 / 2

=11 / 2

=5.5

= 5 th term + 6 th term /2

=77 + 85 /2

=162 / 2

=81

mode means most repeating number . so in this given data 77 is repeated two times while others occured just one times . so the mode of the given data is 77.

Mode = 77

Eddi Din [679]
1) The population

Is the set of all the terms that the teacher taught this semester and which he wrote down on the note cards and put in the paper bag.

2) The sample is every set of five cards that is selected by each student.

3) I think the sample is representative because all ther terms have the same probability of being selected. 

Further, given that the cards are replaced every time all the students will face the same population when they are going to select a sample.

Please help me with circle questions below
IRINA_888 [86]

For first question, What is approximate value of "......" this part is missing so please write whose approximate value question is asking to find

For second question we have to find tan\Theta

In right triangle ABC as show in attachment,

tan\Theta = \frac{opposite side}{adjacent side} = \frac{AB}{BC}----(1)

Now AB is given by distance of point A from x axis which will be given by its y - coordinate. So AB = \frac{1}{2}

Similarly BC is the distance of point A from y axis (horizontal distance ) and that will be given by x coordinate of A. So BC = \frac{\sqrt{3}}{2}

Plug these values in equation (1)

tan\Theta = \frac{AB}{BC} = \frac{\frac{1}{2}}{\frac{\sqrt{3}}{2}}

To divide fractions we flip (reciprocal ) bottom fraction and multiply it to top fraction as shown

tan\Theta = \frac{1}{2} \times \frac{2}{\sqrt{3}}

Now 2 in top and bottom cancels out so we are left with

tan\Theta = \frac{1}{\sqrt{3}}

so thats the final answer for tan\Theta
