A distance AB is observed repeatedly using the same equipment and procedures, and the results, in meters, are listed below:69.40
Zina [9179]

Answer:

The most likely length of the line is 69.4012 meters.

The calculated standard deviation amounts to 0.0032 meters.

Step-by-step explanation:

In the problem, the following values are provided:

69.401, 69.400, 69.402, 69.396, 69.406, 69.401, 69.396, 69.401, 69.405, 69.404      

Formula:

\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n}}  

where x_i represent data points, \bar{x} is the average, and n indicates the count of observations.  

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{694.012}{10} = 69.4012

The most likely length of the line is 69.4012 meters.

Sum of squares of differences = 0.0001016

\sigma = \sqrt{\dfrac{0.0001016}{10}} = 0.0032

The calculated standard deviation amounts to 0.0032 meters.

lawyer [9240]

Respuesta:

1/16   2/16  3/16  4/16  5/16  6/16  7/16  8/16 9/16 10/16  11/16 12/16

Explicación paso a paso:

Para identificar las brocas existen dos aspectos a considerar:

1.- Las fracciones que comparten el mismo denominador aumentan en orden ascendente a medida que los numeradores incrementan, lo que significa que entre

9/16   3/16    7/16     5/16   11/16    el orden sería (de menor a mayor)

3/16     5/16     7/16     9/16     11/16

2.- Fracciones con diferentes denominadores pueden convertirse a un denominador común /16 multiplicando la fracción, por ejemplo

1/4   =  1*4/4*4   =  4/16

Aplicando este método, todas las fracciones se transforman al formato mencionado previamente y se organizan

1/4   = 4/16

3/8  = 6/16

1/2  = 8/16

5/8 =  10/16

1/8  =  2/16

Por lo tanto, hay diez brocas, comenzando con 1/16 hasta la número 12 que es 12/16

Finalmente, el orden sería:

1/16   2/16  3/16  4/16  5/16  6/16  7/16  8/16 9/16 10/16  11/16 12/16

Jai Narayan sells two radio sets for 2288 each.
tester [8842]

Answer:

1%

Step-by-step explanation:

The selling price for each radio is $2288.

Total selling price is 2\times 2288=$4576.

Profit is 10%.

Loss is also 10%.

Cost price=\frac{S.P\times 100}{100+gain(in\;percent)}

Cost price=\frac{S.P\times 100}{100-loss(in\;percent)}

Utilizing the formula,

Cost price of the first radio is \frac{2288\times 100}{110}=$2080.

Cost price of the second radio is \frac{2288\times 100}{100-10}=$2542.2.

The combined cost price for both radios totals 2080+2542.2=$4622.2.

Total cost price exceeds total selling price.

Loss equals selling price minus cost price.

Loss is calculated as 4622.2-4576=$46.2.

Loss%=\frac{Loss}{C.P}\times 100

Loss percentage is \frac{46.2}{4622.2}\times 100=1%.

Thus, the loss is 1%.
