Answer:

A)28

B)67.45

C)71.4  

Step-by-step explanation:

We are given the following data:

68,63,67,66,65,87,69,61,86,82,28

a) The outlier in the data is 28 as we can clearly see all the data points in the given data set ranges from 60 to 88 but their is a single entry of 28 which is different.

b) Mean = \frac{\text{Sum of all observations}}{\text{Total number of observations}}\\\\ = \frac{68+63+67+66+65+87+69+61+86+82+28}{11}\\\\=\frac{742}{11} = 67.45

c)Mean = \frac{\text{Sum of all observations}}{\text{Total number of observations}}\\\\ = \frac{68+63+67+66+65+87+69+61+86+82}{10}\\\\=\frac{714}{10} = 71.4

The outlier is 28 because there is a big gap between 28 and 61

to find the mean add all the numbers together then
divide the number of values added

Which number produces an irrational number when multipled by 1/4
BabaBlast [244]

Answer: Any irrational number

Step-by-step explanation:

An irrational number is a number that cannot be expressed as a fraction of two integers where the denominator is different from zero, it is also characterized by the fact that its decimal expression is neither exact nor periodic.

As an example of this we have \pi = 3.141592653 ...

On the other hand, it is necessary to know the following:

-The multiplication of two rational numbers results in a rational number.

-The multiplication of a <u>rational number</u> by <u>any irrational number</u> results in an <u>irrational number.</u>

This means that if we multiply 1/4 (which is rational) by any irrational number, the result will be irrational.

Therefore, the answer is: Any irrational number.

lord [1]

Answer:

50 + 1 + \frac{2}{10} + \frac{4}{100} + \frac{2}{1,000}

Step-by-step explanation:

This is the answer because:

1) 50 and 1 equal to 51

2) The fraction forms of a decimal number is: the decimal number/the decimal number place value

3) Therefore, the answer is 50 + 1 + \frac{2}{10} + \frac{4}{100} + \frac{2}{1,000}

Hope this helps!
