He data set gives the number of hours it took each of the 10 students in a cooking class to master a particular technique. {5, 3, 5, 30, 4, 5, 4, 3, 4, 5} the best measure of center for this data set is

 4.5

Step-by-step explanation:

The given data set : 5, 3, 5, 30, 4, 5, 4, 3, 4, 5

It can be seen that it contains an outlier (30), then the  best measure of center for this data set is median value. [∵ Mean gets affected by outlier extremely.]

First arrange data in an order :  3, 3 ,4 ,4 ,4 ,5 ,5 ,5 ,5 ,30

Since , the number of data values =10 (Even)

Then, Median = Mean of the middle two values

i.e. Median =

Hence, the best measure of center for this data set is 4.5 .

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

b
