Answer: The area of the composite figure is 264 cm square.

Explanation:

In the given figure the are 5 figure are in the composition. 1 square, 3 rectangles and 1 triangle.

The area square is,

A=side\times side

So, area of part (1).

A_1=10\times 10=100cm^2

Base of the triangle is,

Base = 20-3-4-5-2=6 cm

Area of triangle is,

A=\frac{1}{2} \times base\times height

Area of part (2).

A_2=\frac{1}{2}\times 6\times 4=12cm^2

The area rectangle is,

A=length \times breadth

Area of part (3).

A_3=3\times 4=12cm^2

Area of part (4).

A_4=5\times 4=20cm^2

Area of part (5).

A_4=20\times 6=120cm^2

Total area is sum of all area of all parts.

A=A_1+A_2+A_3+A_4+A_5

A=100+12+12+20+120=264cm^2

Therefore the area of the composite figure is 264 cm square.

The length of line in green = 5 cm
the length of line in yellow = 3 cm
the length of line in red = 6 cm
the length of line in white = 16 cm
the total area = 100 + 12 + 12 + 20 + 24 + 96 = 264 cm2

When engaging in weight-control (fitness/fat burning) types of exercise, a person is expected to attain about 60% of their maxim
Nimfa-mama [501]

Answer:

a) <em> standard error of the mean =10.06</em>

<em>b)  The margin of error  = 17.3982</em>

<em>c) 95% of confidence intervals are </em>

<em></em>(89.6018 ,124.3982)<em></em>

<em>d) Lower limit of 95% of confidence interval  = 89.6018</em>

<em>upper limit of 95% of confidence interval  = 124.3982</em>

<em>The Population mean is lies between in these intervals</em>

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

<u><em>Step(i)</em></u><u>:-</u>

Given sample size 'n' = 20

Given sample mean was found to be 107 bpm with a standard deviation of 45 bpm.

<em>Sample mean             </em>x^{-} = 107 bpm<em></em>

<em>Sample standard deviation (S) = 45 bpm</em>

<em>a) standard error of the mean is determined by</em>

<em>     </em>S.E = \frac{S}{\sqrt{n} } = \frac{45}{\sqrt{20} }<em></em>

<em>     S.E = 10.06</em>

<em>b) The margin of error is determined by</em>

<em></em>M.E = \frac{t_{\alpha } X S }{\sqrt{n} }<em></em>

<em>The degrees of freedom  ν   </em>= n-1 =20-1=19<em></em>

<em>   </em>t_{\alpha } = 1.729  

<em></em>M.E = \frac{1.729X 45}{\sqrt{20} }<em></em>

<em></em>M.E = \frac{77.805 }{4.472 } = 17.3982<em></em>

<em>c) 95% of confidence intervals are determined by</em>

<em></em>(x^{-} - t_{\alpha } \frac{S}{\sqrt{n} } , x^{-} + t_{\alpha } \frac{S}{\sqrt{n} } )<em></em>

<em></em>(107 -  1.729\frac{45}{\sqrt{20} } , 107 + 1.729\frac{45}{\sqrt{20} } )<em></em>

<em></em>(107 -  17.3982 } , 107 +17.3982 )<em></em>

<em></em>(89.6018 ,124.3982)<em></em>

<em>d)  </em>

<em>Lower limit of 95% of confidence interval  = 89.6018</em>

<em>upper limit of 95% of confidence interval  = 124.3982</em>

<em>The Population mean is lies between in these intervals</em>

Represent each division problem as a fraction AND a decimal.
romanna [79]

Answer:

1. fraction=51/94

decimal= 51/94 a decimal is approximate: 0.54255 (Rounded to fifth decimal place)

2. fraction= 2/8

decimal= 2/8 as a decimal is 0.25.

3. fraction= 75/5

decimal= 75/5 as a decimal is 15.
