Answer:

Step-by-step explanation:

assuming the triangles would be congruent if you flipped one this would be correct as this is just a ratio. 48/6=8 40/5=8

Find the area of the shape. ( image of 3/4 circle with the radius of 6 ) Answer in exact terms of pi or use 3.14 as pi and enter

Luba_88 [7]

The area of the shape is 84.78 square units

<h3>Area of a circle</h3>

The formula for calculating the area of a circle is expressed as:

A = πr²

where

r is the radius of a circle

Given the following

r = 6 units

pi = 3.14

Substitute

A = 3.14 * 6²

A = 113.04 square units

If the figure is 3/4 of a circle, the area of the shape will be:

A = 3/4 * 113.04

A = 84.78 square units

Hence the area of the shape is 84.78 square units

Answer:

The sample mean is $\bar{x}=1.24$ and the sample median is 0.56

Step-by-step explanation:

The sample mean $\bar{x}$ of observations $x_1,x_2,...,x_n$ is given by

$\bar{x}=\frac{\sum x_i}{n}$

Applying the above definition we get that

The sum of these 15 sample observations is

$\sum x_i = 0.21+\:0.22+\:0.26+\:0.30+\:0.34+\:0.42\:+0.55+\:0.56+\:1.43+\:1.70+\:1.84+\:2.20+\:2.25+\:3.06+\:3.26\\\\\sum x_i =18.6$

and the sample mean is

$\bar{x}=\frac{18.6}{15}=1.24$

The sample median is obtained by first ordering the <em>n</em> observations from smallest to largest (with any repeated values included so that every sample observation appears in the ordered list). Then,

Sample median = The single middle value if n is odd = $(\frac{n+1}{2} )^{th}$

Sample median = The average of the two middle values if n is even = average of $(\frac{n}{2} )^{th}$ and $(\frac{n}{2}+1 )^{th}$

Applying the above definition we get that

The data is already ordered and n = 15 so,

Sample median = $(\frac{15+1}{2} )^{th}=8^{th}$ = 0.56
