<span>you have to take arctan(0) to find the value of theta.
tan^-1 (x)=theta </span>
        
             
        
        
        
Answer:
Original claim is 
Opposite claim is 
Null and alternative hypotheses:


Significance level: 0.01
Test statistic:
We can use TI-84 calculator to find the test statistic and P-value. The steps are as follows:
Press STAT and the scroll right to TESTS 
Scroll down to 2-SampTTest... and scroll to stats.
Enter below information.







Pooled: Yes
Calculate.
The output is in the attachment.
Therefore, the test statistic is:

P-value: 0.4412
Reject or fail to reject: Fail to reject
Final Conclusion: Since the p-value is greater than the significance level, we, therefore, fail to reject the null hypothesis and conclude that the there is sufficient evidence to support the claim that the samples are from populations with the same mean.
 
        
             
        
        
        
Formula
Volume = A_base * height
Solution
Synthetic Division always changes signs of the divisor. Also you add whereas in long division you subtract.
-2   ||  2   +    9  -  8   - 36
                    -4   -10     36
       =================== 
           2       5     -18    0
You can eliminate A and B. You are never left with the same power at the beginning when you do a division.
What you are left with is
A_Base = 2x^2 + 5x - 18
Answer: D
 
        
             
        
        
        
180 ft because its 2 plates to get to second base and the length to each is 90 ft so 90ftx2 (2 because you're trying to get to second base)
