Solve for x9(x + 1) = 25 + x
vaieri [72.5K]
When you expand the equation, you will have
9x + 9=25 + x
Next you have to collect like terms
+x will go over the equality sign to become -x. The same applies to +9
9x - x=23 - 9
9x minus x is 8x
8x=14
Divide both sides by 8
x=14/8
You will have 1 6/8
6 is the remainder while 1 is the number of times 8 divided 14.
In decimal, it will be 1.75
Hope that helped. Good luck

sergejj [24]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

H_0: Management quality and corporate reputation are independent.  

H_1:  Management quality and corporate reputation are not independent.

Test statistic:

\to \chi^2 = \frac{\sum (O-E)^2}{E}

= 0.71429 + 0.0102 +2.8809+0.625+1.75 +0.3333    +0+3.2143+7.5\\\\= 17.02806

The critical \chi^2 fordf = (r-1)(c-1) = (3-1)(3-1)= 4 and \alpha = 0.05 is \chi^2= 9.4877

Test statistic:

17.02806 > 9.4877 therefore rejecting the null hypothesis H_0.

p-value= 0.001909

Interpretation:

There is no internal governance quality as well as the reputation of the organization.
