The radius of sphere is 3.5 cm.
Step-by-step explanation:
<u>SOLUTION</u> :
Here's the required formula to find the radius of sphere :
Substituting all the given values in the formula to find the radius of sphere :
Hence, the radius of sphere is 3.5 cm.
<u>DIAGRAM</u> :
Here's the diagram of sphere with radius 3.5 cm.
The answer is below
a) For a normal model the sample size has to be equal or greater than 30 so that it can be a normal distribution.
b) Given that:
μ = 11.2 minutes, σ = 4.8 minutes, n = 45
The z score determines how many standard deviations the raw score is above or below the mean. It is given by:
For x < 10 minutes
Therefore from the normal distribution table, P(x < 10) = P(z < -1.68) = 0.0465
-15.41

1990 price was 850,000
in 2000
850,000 + 125% = 1,062,500
850,000 + 1,062,500 = 1,912,500
in 2013
1,912,500 - 30% = 573,750
1,912,500 - 573,750 = 1,338,750
