Solve for the mean and median of the following data: 20, 10, 15, 18, 12, 17

<h2><u>Mean and Median</u></h2>

<h3>solve for the mean and median of the following data: 20, 10, 15, 18, 12, 17</h3>

<h3><u>Mean</u></h3>

To find the mean of a data set, use the formula:

<u>mean</u> = <u>sum of the data points</u>/<u>number of the data points</u>

We will determine the sum of the data points.

  • 20 + 10 + 15 + 18 + 12 + 17 = 92

Since the number of data points is 6, we will divide the sum and the number of data points as shown in the formula above.

  • 92/6
  • 15.3

<u>Answer:</u>

  • The mean of the data set is <u>15.3</u>.

<h3><u>Median</u></h3>

To find the median of the data set, arrange the data set into ascending order and the value in the middle is the median. The median should be an even number.

  • 20, 10, 15, 18, 12, 17
  • 10, 12, 15, 17, 18, 20

The middle value is 15 and 17. Find out their sum and divide it into 2.

  • 15 + 17/2
  • 32/2
  • 16

<u>Answer:</u>

  • The median of the data set is <u>16</u>.

The orbit of the planet Venus is nearly circular. An astronomer develops a model for the orbit in which the sun has coordinates
klio [65]
Since the Venus orbits round the sun, the sun is the center of the circular path of the revolution of the planet, Venus.

Thus, the distance of the planet, Venus fron the sun is given by the distance between the points (0, 0) and (41, 53).

Recall that the distance between two points (x_1, y_1) and (x_2, y_2) is given by d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Thus, the distance between the points (0, 0) and (41, 53) is given by:

d= \sqrt{(41-0)^2+(53-0)^2}  \\  \\ = \sqrt{41^2+53^2} = \sqrt{1,681+2,809}  \\  \\ = \sqrt{4,490} =67 \ units

Given that each unit of the plane represents 1 million miles, therefore, the distance from the sun to the Venus is 67 million miles.

Given right triangle GYK, what is the value of tan(G)?
Ludmilka [50]

<u>Answer:</u>

The value of tan(G) in the  right triangle GYK Is \sqrt{3}

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

Given

Measure of angle at G=60^{\circ}

Measure of angle at Y=30^{\circ}

Measure of angle at K=90^{\circ}

To find:

\tan (G)=?

Solution:

In trigonometry we know that

\tan G=\frac{\sin G}{\cos G}

G=60^{\circ}

So,

\sin (60)=\frac{\sqrt{3}}{2}

\cos (60)=\frac{1}{2}

Substituting in the formula we have,

\tan G=\frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}}

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

\tan G=\frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}}

\tan G=\sqrt{3}

Result:

Thus the value of \tan G=\sqrt{3}
