Answer

Step 1 : add: 6+6 =12 and add : 9+9 give us 18 so 6/9=12/18 as a

equivalent continue with the same way: add 12+12=24 and 18+18=36 is

24/36 the last one add 24+24=48 and 36+36= 72 so the last

Equivalent is 48/72

The manager of a fleet of automobiles is testing two brands of radial tires and assigns one tire of each brand at random to the
Darya [45]

Answer:

Brand 1    Brand 2    Difference

37734       35202        2532

45299      41635         3664

36240      35500        740

32100      31950         150

37210       38015       −805

48360     47800        560

38200    37810          390

33500    33215        285

Sum of difference = 2532+ 3664+740+150 −805+  560 +390 +285 = 7516

Mean = d=\frac{7516}{8}

Mean = d=939.5

a) d= 939.5

\text{Sample Standard deviation, s} = \sqrt{\dfrac{(x-\bar{x})^2}{n-1}}

=\sqrt{\dfrac{(2532-939.5)^2+(3664-939.5)^2+(740-939.5)^2 ...+(285-939.5)^2}{8-1}}

=1441.21

b)SD= 1441.21

c)Calculate a 99% two-sided confidence interval on the difference in mean life.

confidence level =99%

significance level =α= 0.01

Degree of freedom = n-1 = 8-1 =7

So, t_{\frac{\alpha}{2}}=3.499

Formula for confidence interval = \left( \bar{X} \pm t_{\frac{\alpha}{2}} \times \frac{s}{\sqrt{n}} \right)

Substitute the values

confidence interval = 939.5 \pm 3.499 \times \frac{1441.21}{\sqrt{8}} \right)

confidence interval = 939.5 - 3.499 \times \frac{1441.21}{\sqrt{8}} \right) to  = 939.5 + 3.499 \times \frac{1441.21}{\sqrt{8}} \right)

Confidence interval −843.396\ to  2722.396

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one.
azamat
To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above:

 -  The<span> room has square dimensions and it has been built with two pieces of sheetrock, a smaller one and a larger one.

 2. Therefore, let's call

 x: the smaller one.
 y: the larger one.

 3. Then, you have that the lenght of the wall is the sum of the smaller one and the larger one:

 x+y

 4. So, the area of the room is:

 (x+y)(x+y)
 (x+y)</span>²

 Therefore, the answer is: (x+y)²
