Answer:
We accept the null hypothesis and reject  the alternate hypothesis. There is no evidence to conclude that the population mean is greater than 29. The population mean is less than or equal to 29.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 29
Sample mean,  = 30
 = 30
Sample size, n = 47
Alpha, α = 0.05
Population standard deviation, σ = 5
First, we design the null and the alternate hypothesis
 
a) This is a one-tailed test because the alternate hypothesis is in greater than direction.
We use One-tailed z test to perform this hypothesis.
b)  , we reject the null hypothesis and accept the alternate hypothesis and if
, we reject the null hypothesis and accept the alternate hypothesis and if  , we accept the null hypothesis and reject  the alternate hypothesis.
, we accept the null hypothesis and reject  the alternate hypothesis.
c) Formula:
 
Putting all the values, we have
 
d) Now,  
Since,  
 
We accept the null hypothesis and reject  the alternate hypothesis. There is no evidence to conclude that the population mean is greater than 29. The population mean is less than or equal to 29.
e) P-value is 0.0853
On the basis of p value we again accept the null hypothesis.
 
        
             
        
        
        
Weird question xD
You have to use the Pythagorean theorem on this one.
a^2 + b^2 = c^2
11^2 + h^2 = 12^2
121 + h^2 = 144
h^2 = 23
h = 4.79583

Answer:
x,y= -1,0
Step-by-step explanation:
 
        
                    
             
        
        
        
The rate of time is measured in feet per minute. 
<span>Because distance = rate * time, </span>
<span>Then rate = distance / time, which gives you feet / min. </span>
        
             
        
        
        
I answer . The white ones are better trust me, but u have to keep them keep clean!
