What’s the answer to question 3?

attashe74 [19]

Answer: The mean is <em>14</em> and the median is <em>14.5</em>

Step-by-step explanation:

To find the mean, add up all of the numbers in the series and divide by the amount of numbers in the series. In this case, the answer comes out to 14.

For the median, you put the numbers in order of least to greatest, as they are listed in the question. You then cross out a number from the left, then a number from the right, one at a time until you are left with either one middle number, or in this case two middle numbers. In this case you are left with 13 and 16. You then find the average of the two middle numbers, which in this case is 14.5

Hope this helps!

A student stands 20 m away from the foot

Ostrovityanka [42]

Answer:

Height of tree is $\approx$ <em>15 m.</em>

<em></em>

Step-by-step explanation:

Given that student is 20 m away from the foot of tree.

and table is 1.5 m above the ground.

The angle of elevation is: 34°28'

Please refer to the attached image. The given situation can be mapped to a right angled triangle as shown in the image.

AB = CP = 20 m

CA = PB = 1.5 m

$\angle C$ = 34°28' = 34.46°

To find TB = ?

we can use trigonometric function tangent to find TP in right angled $\triangle TPC$

$tan \theta = \dfrac{Perpendicular}{Base}\\tan C= \dfrac{PT}{PC}\\\Rightarrow tan 34.46^\circ = \dfrac{PT}{20}\\\Rightarrow PT = 20 \times 0.686 \\\Rightarrow PT = 13.72\ m$

Now, adding PB to TP will give us the height of tree, TB

Now, height of tree TB = TP + PB

TB = 13.72 + 1.5 = 15.22 $\approx$ <em>15 m</em>

the diameter of a circle is 12yd. find the exact area and circumference of the circle. write your answers in terms of pie

Scorpion4ik [409]

So,

The area of a circle is $A = \pi *radius^{2} \\and\\Radius = Diameter \div 2\\\\So\\A = \pi * 6^2\\\\A = 36\pi$

For Circumfrence

$C = \pi * diameter\\C = 12\pi$
