Answer:
273 square feet
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Total ceiling area = 14ft × 20ft = 280 square feet
Diameter of circular light fixture = 3 feet
Radius of circular light fixture = 1.5 feet
So, Area of circular light fixture = π
= 
= 3.14 × 2.25
= 7.065 or 7 square feet
So, area for painting = Total ceiling area - Area of circular light fixture
= 280 - 7
= 273 square feet
A. C=.55p so if p=2, then it would cost $1.10.
B. so since theyre reducing the cost by five cents then the cost per pound is 50 cents so c=.50p and the cost of 2 pounds would be a dollar.
This is an arithmetic sequence with a common difference of 1.23...that means u add 1.23 to each term to find the next term.
1.31 + 1.23 = 2.54
2.54 + 1.23 = 3.77
3.77 + 1.23 = 5 <== ur next term
Answer:
c. The expected values of R and S will be equal, and the variability of R will be greater than the variability of S.
Step-by-step explanation:
This is Central Limit Theorem concept in which independent variables are added and form a normal distribution. The random sample of n sample size is selected which calculates normally distributed mean and variance. The expected value of samples distributor will be higher than the sample distribution.
