kiruha [24]

Answer:

mean for a = 60/10 = 6

mad of a = 2

mean for b = 80/10 = 8

mad of b = 2

Step-by-step explanation:

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. The mean absolute deviation, MAD, is 2.

\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|

m(X) = average value of the data set

n = number of data values

x_i = data values in the set

mean = average.

5) Your stock investments went from $450 in 2013 to $350 ir
Hatshy [7]

The most appropriate choice for percentage will be given by Percentage decrease in the investment is 22.22%

<h3>What Does Percent Mean?</h3>

Using a percentage of 100, we may express a ratio as a %.

Stock investments in this case decreased from $450 in 2013 to $350 in 2014.

Decrease in stock equals $100 ($450 - $355)

Decrease in percentage: 100/450 100 = 22.22%

<h3>What format does a percentage use?</h3>

The definition of percentage is "out of 100." In mathematics, percentages are used to represent parts of a whole, much as fractions and decimals. A total is considered to be made up of 100 equal parts when expressed as a percentage. The symbol % or, less commonly, the abbreviation 'pct' can be used to represent a percentage.

A book was on sale for 40% off its original price. If
Kruka [31]

Answer:

Option C: $30 is the original price of book.

Step-by-step explanation:

Let the original price of book be x

Given that:

Sale price = x - 40% of x

As it is given that the sale price was $18

So,

$18 =  x - 40% of x

By simplifying:

$18 = x - 0.4x

$18 = 0.6x

Dividing both sides by 0.6:

x = $18/0.6

x = $ 30

So the original price of book will be $30

i hope it will help you!
