First, you have to find the area of the rectangular swimming pool (A1), which has <span>10 feet long and 6 feet wide. The area of a rectangle is:
A=A1=LxW
L=10 ft
W=6 ft
When you substitute these values into the formula, you obtain:
</span>
A1=LxW
A1=(10 ft)(6ft)
A1=60 ft²
The area of the Andrea’s backyard (A2) is 400 ft², therefore, the<span> area of Andrea’s backyard, not including the swimming pool (A3), is:
A3=A2-A1
A3=400 ft</span>²-60 ft²
A3=340 ft²
<span>
What is the area of Andrea’s backyard, not including the swimming pool?
The answer is: T</span>he area of Andrea’s backyard, not including the swimming pool, is 340 feet²

Answer:
The answer is in the explanation
Step-by-step explanation:
Mean value = 
= 438
(a) The data appeared to be centered towards 438.
There are little or no skew.
There is no outliers.
(b) yes
(c) standard deviation = s = 14.8955
95% confidence interval = 
=
= (430.3415, 445.6585)
(d) Test statistic
t = 
t = -3.3216
p -value is correctly given in option b.
No, 450 is not a plausible valaue.
I think the answer is Y=2x-6
