Answer:
2.5 is 12PM temp and difference is 3.9
Step-by-step explanation:
-0.5+3 because it is warmer and this is 2.5 also both B and C can be done to get the correct answer. and that is 2.5--1.4 which is the same as 2.5+1.4 which is 3.9
 
        
             
        
        
        
Answer:
I think the answer is repeating because it'd be
0.55
 
        
             
        
        
        
SA: 2pi (r^2)+2pi(r)(h)
In order to find radius (r) of the base you must divide 10 by pi then find the square root of the result
√(10/pi)=r: 1.784cm
h: a) 8.0cm
 b) 6.5cm
 c) 9.4cm
2pi (3.183)+2pi(1.784)(8)=109.673cm^2
2pi (3.183)+2pi(1.784)(6.5)=92.859cm^2
2pi (3.183)+2pi(1.784)(9.4)=125.366cm^2

Answer:
 
  
The p value for this case would be given by:
 
  
For this case the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis so then we can conclude that the true proportion is significantly higher than 0.42 
Step-by-step explanation:
Information given
n=1045 represent the random sample selected
X=502 represent the college graduates with a mentor
 estimated proportion of college graduates with a mentor
 estimated proportion of college graduates with a mentor
 is the value that we want to test
 is the value that we want to test
z would represent the statistic 
 represent the p value
 represent the p value
Hypothesis to test
We want to test if the true proportion is higher than 0.42, the system of hypothesis are.:  
Null hypothesis: 
  
Alternative hypothesis: 
  
The statistic is given by:
 (1)
 (1)  
Replacing the info we got:
 
  
The p value for this case would be given by:
 
  
For this case the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis so then we can conclude that the true proportion is significantly higher than 0.42
