Answer:
388,800 ft^2.
Step-by-step explanation:
Scale = 1 : 180
Actual length, Ls = 180 × 4
= 720 ft
Actual width, Bs = 180 × 3
= 540 ft
Area of a rectangle = Ls × Bs
= 540 × 720
= 388,800 ft^2.
3 feet = 1 yard
12/3 =4
15/3 = 5
4*5 = 20 square yards per room
20*2 = 40 square yards total

Answer:
d. There is a 98% chance that the true proportion of customers who click on ads on their smartphones is between 0.56 and 0.62.
Step-by-step explanation:
Confidence interval:
x% confidence
Of a sample
Between a and b.
Interpretation: We are x% sure(or there is a x% probability/chance) that the population mean is between a and b.
In this question:
I suppose(due to the options) there was a small typing mistake, and we have a 98% confidence interval between 0.56 and 0.62.
Interpreation: We are 98% sure, or there is a 98% chance, that the true population proportion of customers who click on ads on their smartphones is between 0.56 and 0.62. Option d.
14,999(1+.o825)^4= 20,595. $429x48 months= 20,592
Interest rate 8 1/4%
Check 20592/14999= 1.37289
Log(1.37289)/ log(1.0825)= 3.99 years
