Below are tabulated a number of Rockwell G hardness values that were measured on a single steel specimen. Compute

Mashcka [7]

Answer:

a) 48.408

b) 1.235

Step-by-step explanation:

a)

The average hardness value xbar can be computed as

xbar=sum of values/number of values

xbar=(46.5+46.9+49.4+50.3+49.8+48.8+47+47.7+48.3+49.4+47.8+49)/12

xbar=580.9/12

xbar=48.408 (rounded to 3 decimal places).

The average hardness value is 48.408.

b)

The standard deviation hardness value s can be computed as

$s=\sqrt{\frac{sum(x-xbar)^2}{n-1} }$

x x-xbar (x-xbar) ²

46.5 -1.90833 3.64174

46.9 -1.50833 2.27507

49.4 0.99167 0.98340

50.3 1.89167 3.57840

49.8 1.39167 1.93674

48.8 0.39167 0.15340

47.0 -1.40833 1.98340

47.7 -0.70833 0.50174

48.3 -0.10833 0.01174

49.4 0.99167 0.98340

47.8 -0.60833 0.37007

49.0 0.59167 0.35007

Total 16.7692

$s=\sqrt{\frac{16.7692}{12-1} }$

$s=\sqrt{\frac{16.7692}{11} }$

$s=\sqrt{1.5245}$

$s=1.2347$

s=1.235 (rounded to 3 decimal places)

The standard deviation hardness value is 1.235.

Inessa05 [86]

Answer:

for(j = n; j > 0; j--)

System.out.print(\"*\");

Step-by-step explanation:

-A for loop is a repetition control structure.

-It allows the efficiency to write a loop that would otherwise be written a couple of times.

-The output is a single line comprising n asterisks,

-The number of asterisks printed will be equivalent to the n-value declared.

Solve for x<br> x^9=12^2x12^7

jekas [21]

Answer:

<h2>12</h2>

Step-by-step explanation:

Hi!

Here is your answer,

I will explain in step by step,

${x}^{9} = {12}^{2} \times {12}^{7}$

Here we can simplify this further using this law,

${a}^{m} \times {a}^{n} = {a}^{m + n}$

So we will get,

${x}^{9} = {12}^{7 + 2} \\ {x}^{9} = {12}^{9}$

Since the powers are same we can cancel it out and we will get,

$x = 12$

(Hope this answer helped :))
