Answer: C) angle 2 and angle 7
Imagine the parallel lines form the boundaries of river. Angles 3, 4, 5 and 6 are considered interior angles as they are in the river. Angles 1, 2, 7, 8, 9 and 10 are exterior because they're outside the river.
Angles 2 and 7 are on opposite sides of the transversal cut that I've highlighted in red (see diagram below). So that's why they're considered alternate. Combine "exterior" and "alternate" to get "alternate exterior"
For this case we must divide the following expression:
The expression can not be simplified. When dividing we have that its decimal form is given by:
3,201550
If we convert to a mixed number we have:

Answer:
Answer:
Null Hypothesis, :
= 1,100 square feet
Alternate Hypothesis, :
< 1,100 square feet
Step-by-step explanation:
We are given that the mean area of several thousand apartments in a new development is advertised to be 1,100 square feet.
A consumer advocate has received numerous complaints that the apartments are smaller than advertised.
<u><em>Let </em></u><u><em> = mean area of several apartments.</em></u>
So, Null Hypothesis, :
= 1,100 square feet
Alternate Hypothesis, :
< 1,100 square feet
Here, <u>null hypothesis states that</u> the mean area of apartments are same as advertised.
On the other hand, <u>alternate hypothesis states that</u> the mean area of apartments are smaller than advertised.
So, this would be the appropriate null and the alternative hypothesis to test this claim.
