Answer:
Reject Null Hypothesis given that  P-value < ∝ 
Step-by-step explanation:
Applying the Five ( 5 ) step model and assuming ∝ = 0.05 
First step : determine the Null hypothesis
H0 : Age and support for Anti-smoking = independent 
Second step : Determine the alternate hypothesis
Ha : Age and support for Anti-smoking ≠ independent 
Thirdly : Identify significance level ( ∝ ) = 0.05
4th step : Calculate the Test statistic and P-value
Chi-squared test = 36.1429 using excel function 
P-value =  1 - CHISQ.DIST(36.1429, 1, TRUE)  < 0.0001
finally : we can conclude that Age and support for Anti -smoking are not Independent hence we Reject The Null hypothesis. Given that 
P-value < ∝

 Answer:
x = 3π/4, 5π/4
Step-by-step explanation:
cos(x+2π) = -√2/2, [0,2π]
cos(x)cos(2π)-sin(x)sin(2π) = -√2/2
cos(x) = -√2/2
x = 3π/4, 5π/4
Remember that the cosine function is periodic, so cos(θ+2π)=cos(θ).
 
        
             
        
        
        
Answer: 
Step-by-step explanation:
Given
The recipe calls for 2 Pounds of ground pork and 3.5 pounds of ground beef
Suppose x is the cost of ground pork
So, the cost of ground beef is 
The total cost of meat is 
The total cost can also be written as

So, the cost of ground pork is
