Answer:
6/8, 9/12
Step-by-step explanation:
I'm assuming you are referring to the radius of a square
The first thing we have to do is divide by pi, because it's the last thing you do when calculating the area.
2289.06/3.14
729
Now, we have to take the square root of this number because the radius in the area formula is squared.
729^1/2
27
So, the radius is 27.
Answer:
c. 0.1391 < Ï < 0.2311
Step-by-step explanation:
The formula for Confidence Interval is given as:
Mean ± z × Standard deviation/√n
Z score for 98% confidence interval = 2.326
Mean = Significance level = 100% - 98%
= 2% = 0.02
Standard deviation = S=0.0165
n= 37
Hence,
Confidence Interval =
0.02 ± 2.326 × 0.0165/√37
0.02 ± 0.0063094687
Confidence Interval
0.02 - 0.0063094687
= 0.1391
0.02 ± 0.0063094687
= 0.2311
Hence, the Confidence Interval = (0.1391, 0.2311)
= c. 0.1391 < Ï < 0.2311
