Answer:
d = 4 units
Step-by-step explanation:
The diameter is twice the radius
d = 2r
d = 2(2)
d = 4 units
12 x b = 480
12 x 40 = 480
The answer is 40
The answer is 229,171. hope this helps
C=pi×r2 if there is only the diameter then take half of it
Answer: 0.7752
Step-by-step explanation:
Given : The proportion of all homes purchased in 2004 were considered investment properties estimated by NAR: p = 0.23
Sample size : n= 800
Required sample proportion : 
Now , the probability that at least 175 homes are going to be used as investments will be :
[using p-value calculator or z-table]
Hence, the required probability = 0.7752
