Answer:
12 ft
Step-by-step explanation:
Length = x
Area = length * width = x * 8 = 8x
so 8x = 96
x = 12 ft
Answer:
The null hypothesis is given as
while the alternate hypothesis is 
Step-by-step explanation:
As per the the given data
p1=Proportion of Homeowners who would buy the security system
p2=Proportion of Renters who would buy the security system
As the null hypothesis states that there is no difference in the test thus it is given as

This states that there is no difference between the probabilities of the homeowners buying the security system and the renters buying the security system.
The Alternative hypothesis is the other possibility of the null hypothesis. i.e It negates the null Hypothesis and is given as

This is a problem of Difference-of-squares. We know that for a difference of squares

the factorization is given by:

To learn this you need to remember that a <em>difference</em> means <em>subtraction.</em> So applying those concepts we can solve this problem step by step.
Applying distributive property:

Applying distributive property again:

Simplifying:
<em>The correct answer is C</em>
