The outlier, 78, is removed from the data set shown.23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78

How does this affect the range?

A.) The range is decreased by 4.

B.) The range is decreased by 16.

C.) The range is decreased by 22.

D.) The range is decreased by 33.

Answers

An outlier of a set of data is a data value that is too small or too large compared to other values in the set of data. Range of a set of data is the difference between the largest data value and the smallest data valu in the set of data. Range of 23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78 is 78 - 23 = 55 When the outlier 78 is removed, the range of the data set 23, 23, 25, 27, 34, 34, 35, 41, 45, 45 is 45 - 23 = 22 Thus, when the outlier 78 is removed, the range of the data set decreases by 55 - 22 = 33. Therefore, the correct answer to the question "The outlier, 78, is removed from the data set shown. 23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78 How does this affect the range?" is "The range is decreased by 33." (option D).

Sally buys a handbag. there was a discount of 30%. if sally paid, $20, what was the original price?

Answers

the original price is $28.57

If the discount is 30% then the amount paid is 70% of the original price. Sally paid $20, it is the discounted price, equivalent to 70%.

We need to divide $20 by 70% to get the original price or the 100%.

$20 / 70% = $28.57 original price.

Since the handbag was has discount of 30%, we multiply the original price with the 30% to get the discount value.

$28.57 * 30% = $8.57 discount

To check: deduct the discount from the original price to get the discounted price.

$28.57 - $8.57 = $20 discounted price. price paid by Sally
