Answer in fraction form = 9/8
Answer in decimal form = 1.125
note: the improper fraction 9/8 converts to the mixed number 1 & 1/8
To get this answer, we divide both sides by 8 to isolate n. The expression 8n really means "8 times n". We divide to undo the multiplication. 
 
        
             
        
        
        
Answer:
Hello some parts of your question is missing below is the missing part 
answer : A) p-value =  0.0019 , 
The level of significance ( 0.05 ) > p-value ( 0.0019 ) 
B) There is no dependence between the two ratings 
Step-by-step explanation:
A) using a 0.05 level of significance and test for independence of the quality of management 
Test statistic :  ∑ ( Oi - Ei )^2 / Ei
  ∑ ( Oi - Ei )^2 / Ei
= [(40-35)^2 / 35 ] +  [(25-24.5)^2 / 24.5 ] +  [(5-10.5)^2 / 10.5]  +  [(35-40)^2 / 40]  +  [(35-28)^2 / 28]  +  [(10-12)^2 / 12]  +   [ (25-25)^2 / 25 ]  +  [(10-17.5)^2 / 17.5 ]  + [(15-7.5)^2 / 7.5]  =  17.03  
p-value = 0.0019
Df = 4  , 
The level of significance ( 0.05 ) > p-value ( 0.0019 ) 
B) There is no dependence between the two ratings

Answer:
The variable that may change in response to the increase of the drug is the GAD symptoms by a 37,5%.
Step-by-step explanation:
 According to the results of the first experiment with a mass of 200 mg of Drug R, they obtain a reduced of the GAD symptoms by a 25 percent evidenced by the Hamilton Anxiety Scale. 
 If they decided to increase the mass of Drug R to 300 mg the results expected are a increase of the porcentange of the reduced symptoms of generalized anxiety disorder, according to the tendence of the first hypothesis and the Hamilton Anxiety Scale.
 We can express this increase by using the three simple rule. Where if 200 mg of Drug R reduced the 25% of the GAD symptoms, if we increase to 300 mg of Drug R how much porcentage this amount will be reduced.
 Doing the maths 300mg × 25%=7500mg%, 
     ⇒ 7500mg% ÷ 200mg = 37,5%.
 <u>In conclusion</u> if they increased the mas of Drug R to 300 mg they will be reduced the generalized anxiety disorder (GAD) to a 37,5%. 
 
        
             
        
        
        
We have to find how many seconds are in one hour.
There are 60 seconds in one minute, with 60 minutes in every hour.
60×60=3600
Now, see how many 25 seconds are in 3600 seconds.
3600÷25= 144
Now, we can multiply 144 by 14 or .25 since we are trying to find per hour.
144×.25= 36
36h
H being the hours you're trying to find. It runs 36 miles per hour.
