8 0

Step-by-step explanation:

the area is

length × width

increasing the length by 30% means multiplying the original length by 1.3.

increasing the width by 10% means multiplying the original width by 1.1.

so, the new area is (by using the old length and width)

length × 1.3 × width × 1.1 = length × width × 1.3×1.1 =

= old area × 1.3 × 1.1 = old area × 1.43

so, the area increases by 43%.

The five-number summary for a data set is given below. 1.3 3.8 4.1 4.4 12.4 Using the 1.5 x IQR Rule, any data value _____ than
mixas84 [53]

Answer:

Any data value <u>less</u> than 2.9 should be flagged as a suspected outlier.

Step-by-step explanation:

We have been given the five-number summary for a data set is given below. 1.3  3.8  4.1  4.4  12.4. Using the 1.5 x IQR Rule, any data value _____ than 2.9 should be flagged as a suspected outlier. We are asked to fill in the given blank.

Our given points (1.3  3.8  4.1  4.4  12.4) represent minimum point, 1st quartile, median, 3rd quartile and maximum point.

First of all, we will find interquartile range by subtracting 1st quartile from 3rd quartile.

IQR=4.4-3.8=0.6

Using 1.5 x IQR Rule, we will get our outliers as:

3.8-(1.5\times IQR)\Rightarrow3.8-(1.5\times 0.6)=3.8-(0.9)=2.9    

12.4+(1.5\times IQR)\Rightarrow12.4+(1.5\times 0.6)=12.4+(0.9)=13.3

Therefore, any data value less than 2.9 and greater than 13.3 should be flagged as a suspected outlier.
