Answer:
For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:
Null hypothesis (H0): 
Alternative hypothesis (H1): 
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no

A:
Width of the deck =
units
Length of the deck =
units
So area of rectangular deck = Length * width
= 
Area = 
Area=
units square
As mentioned in part B, the area of the pool is
so the combined area of the deck and pool is
Area = area of rectangular deck + area of pool
=
unit square
B:
The area of only the deck is
unit square

Answer:
<h2>-3 ; 3</h2>
Step-by-step explanation:
4x² - 36 = 0 ⇌ (2x)² - 6² = 0 ⇌ (2x - 6)(2x + 6) = 0 ⇌ 2x - 6 = 0 or 2x + 6 = 0
⇌ x = 3 or x = -3
