Answer:
f(x)=7x'3-2x'2+4x-5
you have to subtract the the exponents by one and multiply by the coefficient

Step-by-step explanation:
Answer:
you<u> accept </u>the alternative hypothesis
Step-by-step explanation:
The null and alternative hypothesis can be computed as follows:
The sample proportion 
The test statistics can be computed as:
Z = -2.5
The P-value = 2( Z< -2.5)
From the tables;
The P-value = 2 (0.0062)
The P-value = 0.0124
The significance level = 0.01
Since the P-value is > significance level; we fail to reject the null hypothesis.
Conclusion: we accept the alternative hypothesis
Answer: The average person doesn't live 1 million hours. 1 million hour is 114 year. That is much more than 78 years. 1 million ours is too much. You would need 683280 to make it 78 years.
