The formula for volume is width * height * length or w*h*l. to do this problem you have to do 8*6*10 which is 480. so, the volume of the room is 480 ft^3 (cubed).

Answer:
the two groups differed in their attitudes toward advertising, significantly
Step-by-step explanation:
given that until recently a number of professions were prohibited from advertising. In 1977, the U.S. Supreme Court ruled that prohibiting doctors and lawyers from advertising violated their right to free speech. The paper "Should Dentists Advertise?" Journal of Advertising Research, June 1982) compared the attitudes of 101 consumers and 124 dentists to the questions "I favor the use of advertising by dentists to attract new patients".
Hypotheses would be
H-0: the groups do not differ
H-a: The two groups differ significantly
(two tailed chi square test)
Observed
Group Strongly agree Agree Neutral Disagree Strongly disagree Total
Consumers 34 47 9 6 5 101
Dentists 9 18 23 28 46 124
Expected is calculated as row total * column total / grand total for each cell
chi square = (obs - exp)^2/Exp for each cell added
chi square = 79.2716
rxc 5x2
df = 4x1 =4
p value <0.00001
Since p < alpha say 0.01, we reject null hypothesis.
the two groups differed in their attitudes toward advertising, significantly
The function is y=2x
this means that the solutions will have the form (x, y)=(x,2x).
For example: (0,0),(1,2),(2,4),(3,6) are solutions.
The first answer choice satisfies the above conditions.
The second answer choice contains (2,2), and (2,6), both of which do not satisfy the (x,2x) condition, so it's not correct.
The third answer choice contains (4,2), which again does not satisfy (x,2x), so not the right answer.
