Q#4:- Consider the problem of determining whether or not different brands of tiers exhibit different amount of tread loss after 20,000 miles of driving. A fleet manager wishes to consider four brands A, B, C, and D that are available and make some decision about which brand might show the least amount of tread wear after 20,000 miles. The variable to be measured (i.e Response variable or study variable) is the difference in maximum tread thickness on a tire between the time it is mounted on the wheel of a car and after it has completed 20,000 miles on this car. Because of the performance of the cars four cars were used and each car got one tire of each brand and the following data about difference in thickness in mils(0.001 inch) were recorded Car I II III IV B (14) D (11) A (13) C (9) C (12) C (12) B (13) D (9) A (17) B (14) D (11) B (8) D (13) A (14) C (10) A (13) (a):- Test the hypothesis that the performance of four brands of tires are same. (b):-Calculate C.V and interpret it.

A rectangular room has a perimeter of 70m what could be the length of the longest side of the room​

Answers

Answer:

34

Explanation:

1+1+34+34 = 2+68=70

if we consider only whole numbers the longest side could be 34

The length of the longest side is 24m

This question appears to be incomplete

Here are the options of this question:

A. 7m

B.11m

C. 24m

D. 35m

A rectangle is a 2-dimensional quadrilateral with four right angles and four vertices.

The longer side of a rectangle is known as the length.

The shorter side of the rectangle is known as the width

The perimeter of a rectangle = 2 x (length + width)

We would begin by inputting the options into the above formula

If the longest side is 7 meter

70 = 2(7 + width)

35 = 7 + width

width = 35 - 7 = 28m

Based on the above calculations, 7 is not the longest side

If the longest side is 11 meters

70 = 2(11 + width)

35 = 11 + width

width = 35 - 11 = 24m

Based on the above calculations, 11 is not the longest side

If the longest side is 24 meters

70 = 2(24 + width)

35 = 24 + width

width = 35 - 24 = 11m

Based on the above calculations, 24 is the longest side

If the longest side is 35 meters

70 = 2(35 + width)

35 = 35 + width

width = 35 - 35 = 0m

Based on the above calculations, 35 is not the longest side
