An insurance institute conducted tests with crashes of new cars traveling at 6 mi/h. the total cost of the damages was found for a simple random sample of the tested cars and listed below. find the a)mean, b)median c) mode, d) midrange for the given sample data. do the different measures of center differ very much? $7,431 $4,859 $8,961 $6,372 $4,363

Mean = $6,397.2

Median = $6,372  

Midrange = $6,662

Step-by-step explanation:

We are given the following data:

$7,431, $4,859, $8,961, $6,372, $4,363

Formula:

Mode is the most frequent observation in the dataset.

Mean =

Median:

Data in increasing order: 4363, 4859, 6372, 7431, 8961

Median = = 6372

Mode: All values appeared once.

Midrange =

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
