The Answer is A. 5070π in3
You need to multiple both fractions so that they share a common denominator. In this case, it's 60.
7/12= 35/60
1/5= 12/60
You can see that they are not equal, and that 7/12 is greater than 1/5 :)
a3=9
assuming the pattern is constant, a3 is right in the middle of a1 and a5 so the answer would be right in the middle of 6 and 12. the average of 6 and 12 is 9, so a3=9.
hope this helps!
The answer is 20 since 1/5 of 20 is 4, and 20 + 4 = 24.
Answer:
The null hypothesis is 
Step-by-step explanation:
According to the Centers for Disease Control and Prevention, the proportion of U.S. adults age 25 or older who smoke is .22
This means that at the null hypothesis, it is tested if the proportion is in fact 0.22, that is:

A researcher suspects that the rate is lower among U.S. adults 25 or older who have a bachelor's degree or higher education level.
At the alternative hypothesis, it is tested if the proportion is lower than 0.22, that is:
